Use HDF5 from minGW on windows - compilation

I'm trying to compile and link to HDF5 with a Fortran program, but I'm getting a run-time error. I've followed closely the procedure described in the answer to this question
Use HDF5 from intel fortran on windows
I've set PATH in the environment variables instead of setting them in visual studio. I moved all of the generated .mod and .lib files to the mod and lib folders in my project folder.
From the command prompt, my compiler config looks like
gfortran --version
GNU Fortran (x86_64-posix-seh-rev0, Built by MinGW-W64 project) 4.9.2
gmake --version
GNU Make 3.81
And my makefile looks like
ifdef SystemRoot
PATHSEP2 = \\
else
PATHSEP2 = /
endif
PS = $(strip $(PATHSEP2))
OBJ_DIR = obj
MOD_DIR = mod
LIB_DIR = lib
FC = gfortran
FCFLAGS = -I$(MOD_DIR) -g -Wall
FLFLAGS = -I$(MOD_DIR) -L$(LIB_DIR) -l$(LIB_DIR)hdf5_fortran
SRCS_F = testHDF5.f90
TARGET = testHDF5
all: $(TARGET)
testHDF5: testHDF5.f90
$(FC) -o $# testHDF5.f90 $(FLFLAGS)
$(OBJ_DIR)$(PS)%.o: %.f90
$(FC) $(FCFLAGS) -c -o $# $<
I've changed the hdf5_fortran.lib to libhdf5_fortran.lib because of what I read here
http://www.mingw.org/wiki/specify_the_libraries_for_the_linker_to_use
When I run gmake, I get
gfortran -o testHDF5 testHDF5.f90 -Imod -Llib -llibhdf5_fortran
And when I try to run the executable, a window pops up that says "The application was unable to start correctly (0xc000007b). Click OK to close the application."
This link
http://www.solveinweb.com/solved-the-application-was-unable-to-start-correctly-0xc000007b-click-ok-to-close-the-application/
Suggests that it is due to incompatibility of 32-bit to 64-bit. I'm using a 64-bit machine, and I did download a 32-bit version of CMake, but only because there doesn't seem to be an available version for 64-bit machines. In addition, this link
http://www.cmake.org/pipermail/cmake/2010-September/039375.html
Suggests that it shouldn't matter. So my question is, where did I go wrong? Are there any glaring mistakes with what I've shown so far?
UPDATE:
I found out that the runtime error was due to not specifying a path, in this case HDF5_DIR. In the USING_HDF5_CMAKE document, it says to specify the environment variable
HDF5_DIR=C:/Program Files/HDF_Group/HDF5/1.8.x/cmake/hdf5
Which fixed the problem of the application crashing at the very start. But now, I'm getting the error
HDF5-DIAG: Error detected in HDF5 (1.8.14) thread 0:

I suppose the first error

Is the most important one since that may trigger later ones. According to this thread
http://hdf-forum.184993.n3.nabble.com/HDF5-Fortran-Fail-to-execute-of-a-basic-F90-program-td4026778.html
It is suggested that the same compiler is used to build the library as building the fortran source code (if I'm not mistaken). During the build using CMake, I specified to use MinGW, which I believe is used during both builds, right?
Again, any help on this is greatly appreciated.

I contacted hdf5 support in regards to this problem
Platform/OS:
Windows 7
Product/Version:
HDF5, Latest download
Description:
Hi, I'm having trouble getting HDF5 working on my windows machine with fortran. Below is an outline of what I've done, and after I show the error I get.
1.1) Download and install CMake, Windows (Win 32 Installer) from http://www.cmake.org/download/
1.2) I did not add CMake to the system PATH, because it was too long.
1.3) I manually added "C:/Program Files (x86)/CMake/bin" to the PATH (for user)
in computer->properties->advanced system settings->environment variables 2.1) Download and install HDF5
2.2) I manually added "C:/Program Files/HDF Group/HDF5/1.8.14/cmake/hdf5" to the PATH (for user) in computer->properties->advanced system settings->environment variables
3.1) I created a new, empty, directory (/Project/) and copied HDF5Examples-0.1.1-Source.zip and HDF518 Examples.CMAKE to it. 3.1) Downloaded hdf5-CMakeWindows.zip from http://www.hdfgroup.org/HDF5/release/cmakebuild.html and unzipped
file to find a folder named CMake.
3.2) Opened CMake GUI, set Source Code Dir = CMake/hdf5-1.8.14 folder
3.3) Set Where to build binaries Dir = /Project/ (project folder containing HDF5Examples-0.1.1-Source.zip and HDF518 Examples.CMAKE)
4.1) In the CMake GUI, I pressed Configure, (selected MinGW and default from the 1st and 2nd drop down respectively), Configure. Checked BUILD_SHARED_LIBS and HDF5_BUILD_FORTRAN. Configure, configure, generate.
4.2) I navigated to the bin directory of the CMake folder and copied the library files, .dll files, and .mod files to an empty test folder (/test_HDF5/), where I separated them into lib/mod folders.
4.3) I created a makefile which, if done correctly, linked the .lib files.
4.4) I compiled the files and linked the libraries and there seemed to be no errors, nor warnings. When running the testHDF5.exe I received the following error: The application was unable to start correctly (0xc000007b). Click OK to close the application. I believe this is a configuration issue, and I'm not sure how to resolve it.
I'm very new with linking libraries and I'm just trying to use HDF5 as a data exporting tool with my existing fortran code. Any help is greatly appreciated.
Sincerely, Charlie Kawczynski
And their response was, as of April 14 2015, that MinGW is not supported:
Hi Charlie,
We do not support MinGW at this time. The developer had tried
building with Fortran and was not able to get it to work.
We do have a user forum where you can post questions. However, others
have posted issues about MinGW and Fortran that have not been resolved. :(
For information on the HDF Forum, see:

Hope this helps others.

Linking libxml with MinGW using OMNETPP shell on windows 10

How can I link libxml on MinGW when using an omnetpp shell?
I am using omnetpp on a windows 10 machine.
My problem happens when I am trying to install the 3rd party package from here
I think that there is a problem in the Makefile failing to locate the libxml library
Following Rudi's answer (following the question) I changed the Makefile libxml path to I/mingw64/include/libxml2 but I still
get a undefined reference to 'xmlFunctionName' error (for many function names)
I tried to isolate the problem and to compile a sample of code from libxml2
Following the compilation guide: using gcc `xml2-config --cflags --libs` -o tree2 tree2.c
I got a fatal error: 'libxml/parser.h' file not found
When I replaced xml2-config --cflags --libs with -I/mingw64/include/libxml2
I got the same error as before undefined reference to 'xmlFunctionName'
what can I do to resolve that issue?
To this specific problem: libxml2 is actually already present as OMNET 5.x also uses it. All dependencies and tools are available in the tools/win64/mingw64 directory. The problem is that (for unknown reasons) the include file of the include/libxml2/libxml folder. The configure script correctly detects this and makes it available in the Makefile.inc as XML_CFLAGS= = -I/mingw64/include/libxml2
This must be added to the compiler flags for each file where you want to use the XML parser. (the library files are in the /mingw64/lib folder) so those are detected and can be used without additional config.
Generally, third party libraries should be available in the /mingw64/include and /mingw64/lib folders. You can either copy them manually there or try to install it with the mingw package manager (however that will most likely ruin your omnet installation as mingw64 is not particularly consistent and it is a rolling release - i.e. this is highly not recommended).

How to build Qt5 as static libraries under Windows

To distribute a Qt appication to Windows users as a simple .exe file, one would need to link statically with a static version of Qt libraries. Assume we distribute our license under an open license so that static linking of Qt is allowed. So we just need static library binaries of Qt5Core, Qt5Gui, Qt5Widgets. How to get them?
The binary distribution of Qt5 comes with dynamic libraries only. It contains some .lib files as well - but beware, these are not the static libraries, but some auxiliary files. They can be distinguished from true static libraries by their size: true static libraries are much bigger (many MB in the case of Qt5 components). So we need to statically compile Qt5 ourselves. This turns out to be surprisingly difficult.
The official instructions (http://doc.qt.io/qt-5/windows-building.html) are almost useless: Way too short, they do not even convey an idea of the difficulty of the task. A precise, up-to-date, step-by-step guide how to compile Qt5 into static libraries is currently missing. We should have it here.
The short answer: Don't waste your time on this. Link dynamically, and let an installer distribute your application. This is the only mode that is seriously supported by Qt5 and by CMake. Working without their support and against their advise is close to hopeless. Setting up an installer is far easier (though no fun either - we currenly use black magic from https://hk.saowen.com/a/d1cf90fcfea6d511629fd5a6c8113808721a7f19656677e8a5fab370a8d35cd4).
The long (yet incomplete) answer, in case you want to outsmart me:
The following steps brought me deceptively close to a solution. I succeeded in building static libraries, but I failed to link my application: Upon getting hundreds of LNK2001 and LNK2019 errors caused by cryptic unresolved external symbols, I had to give up.
So here comes a step-by-step description of what worked for me in October 2018 on a Windows10 virtual desktop. For each installation step, a check is indicated. If a check fails then fix the problem before proceeding further.
To start, install some tools that are needed later on:
Perl, needed for zlib and openssl configuration:
Skip if "perl -v" works.
Get installer from https://www.activestate.com/activeperl
Run installer -> will install to C:\Perl64.
Check: Restart terminal and try "perl -v".
An editor that can handle Unix end-of-line. Notepad won't do. Install vim, emacs, or whatsoever.
chocolatey package manager, needed to install flex and bison:
Run admin shell (Circle Menu > search for "Command" > right-click on "Command Prompt" > run as Admin)
Copy download command from https://chocolatey.org/install#install-with-cmdexe
Paste command to admin shell, and watch installation
Check: in terminal, try command "choco"
flex and bison, needed by qtbase compilation:
It's not obvious to get the right version of flex. From gnuwin32.sourceforge.net I got an outdated flex that missed a command-line argument required during Qt compilation. Compiling flex from source introduces a tail of further dependences. The simplest solution I found uses the Chocolatey package manager.
In admin shell, run: "choco install winflexbison3". This creates a directory X that contains the binaries win_flex.exe and win_bison.exe and a supporting "data" folder. Find out the location of X. In my case, X=C:\ProgramData\chocolatey\lib\winflexbison3\tools
Check: cd X, and run "win_flex --version", "win_bison --version".
During Qt compilation, these tools will be needed under their standard names "flex" and "bison". Therefore we need symbolic links flex->win_flex, bison->win_bison.
mlink X\flex.exe X\win_flex.exe
mlink X\bison.exe X\win_bison.exe
note: mklink needs absolute paths to work reliably
note: the symlink must not go to another directory lest bison won't find the "data" folder
Add X to the %PATH%
Check: in any shell, try "flex --version" and "bison --version"
So far for the tools. Now we need two libraries that must be statically linked to Qt (magic learned from https://stackoverflow.com/a/41815812/1017348):
Build static zlib:
Download https://zlib.net/zlib1211.zip
Unpack to C:\Development\zlib-1.2.11
Edit the file win32\Makefile.msc with an editor that can handle Unix EOLs:
Find the line starting with CFLAGS
Replace -MD with -GL -MT -Zc:wchar_t-
Find the line starting with LDFLAGS
Replace -debug with -opt:icf -dynamicbase -nxcompat -ltcg /nodefaultlib:msvcrt
Build zlib using the following command (should take less than a minute):
nmake -f win32/Makefile.msc AS=ml64 LOC="-DASMV -DASMINF -DNDEBUG -I." OBJA="inffasx64.obj gvmat64.obj inffas8664.obj"
Check: as a result, the source directory must contain zlib.lib (856kB), inter alia.
Build static openssl library:
Download https://www.openssl.org/source/openssl-1.1.1.tar.gz
Unpack to C:\Development\openssl-1.1.1
Copy files from zlib: cd zlib-1.2.11; xcopy zconf.h ..\openssl-1.1.1\ ; same for zlib.h zlib.lib zlib.pdb
cd ..\openssl-1.1.1
perl Configure VC-WIN64A no-asm no-shared zlib no-zlib-dynamic threads --prefix=C:\opt\local_x64
note: I added "no-asm" to avoid installation of NASM (Netwide Assembler)
note: I changed prefix, since only admins can install to C:\Windows
Edits the file ''makefile'':
Find the line that starts with: CFLAG
Append: /Zc:wchar_t- /GL /Zi
Find the line that starts with: LDFLAGS
Replace /debug with /incremental:no /opt:icf /dynamicbase /nxcompat /ltcg /nodefaultlib:msvcrt
Find the line that starts with: CNF_EX_LIBS
Replace ZLIB1 with zlib.lib
Build: "nmake"
Check: directory must contain openssl.lib (size?)
Now we are ready to build qtbase from source, using the command-line version of the Visual Studio C++ compiler:
Download (update location for latest Qt): https://download.qt.io/archive/qt/5.11/5.11.2/submodules/qtbase-everywhere-src-5.11.2.zip
Unpacking takes ca 20'
Move the source directory to the Local Disk (C:\Development)
To work with Visual Studio, use a specially configured terminal. Use Taskbar>Circle>Search to launch "x64 Native Tools Command Prompt for VS 2017"
cd qtbase...
Check: configure --help
configure -platform win32-msvc2017 -opensource -confirm-license -release -static -openssl-linked no-dbus -no-libpng -no-libjpeg -nomake examples -nomake tests -prefix C:\opt\local_x64 -I C:\Development\openssl-1.1.1\include -L C:\Development\openssl-1.1.1 -D OPENSSL_LIBS=C:\Development\openssl-1.1.1\libssl.lib
while debugging "configure", it may be necessary to delete config.cache.
option -I does not work with relative paths
the label "win32" may look wrong if we want to use Qt in a 64bit application, but we are advised not to worry: building Qt under Windows: really with "-platform win32-msvc2017"?
I don't know how to get rid of Sql: https://bugreports.qt.io/browse/QTBUG-71253
libpng and libjpeg are needed by optional code. They are provided in src/3rdparty, which tends to provoke clashes with system provided library versions. Therefore, we build without PNG and JPG support.
nmake
Check: static libraries (big .lib and small .prl) land in directory lib/
54.7 MB Qt5Core.lib
23.4 MB Qt5Widgets.lib
18.2 MB Qt5Gui.lib
07.4 MB Qt5Network.lib
...
That's it, we have static Qt libraries. Only, as said above, this did not help me when I tried to link my application with these libraries.

Building Clang on Windows

I'm trying to build LLVM/Clang on Windows 7 with Microsoft C++ 2013. Building LLVM spat out a few error messages along the way but mostly seemed to be succeeding and did end up creating a folder full of exe's so that part seems to have worked. When I try to build Clang:
C:\clang>\CMake\bin\cmake.exe ..\clang-3.4 -DCLANG_PATH_TO_LLVM_BUILD=/llvm
CMake Error at CMakeLists.txt:29 (message):
Please set CLANG_PATH_TO_LLVM_BUILD to a directory containing a LLVM build.
And I get the same error message whether I omit CLANG_PATH_TO_LLVM_BUILD, define it in CMakeLists.txt or an environment variable instead of the command line, set it to possibly relevant subdirectories of /llvm etc.
What am I missing?
You're not following the instructions on this page correctly, under "Using Visual Studio". You will end up with
/
/llvm
/llvm/CMakeLists.txt
/llvm/tools/clang
/llvm/tools/clang/CMakeLists.txt
Step 4, repeated here for clarity:
Run CMake to generate the Visual Studio solution and project files:
cd ..\.. (back to where you started)
mkdir build (for building without polluting the source dir)
cd build
If you are using Visual Studio 2012: cmake -G "Visual Studio 11" ..\llvm
That last bit needs to be run from inside the VS Command Prompt, but you seem to have that sorted out. You can also generate "NMake makefiles" if you don't use the IDE to build. Anyways, the point is that you should call cmake on the toplevel CMakeLists.txt file, not on the clang one directly. Clang will be built as part of the build process. You can even add libc++ and compiler-rt to the llvm/projects directory to have these built automatically on platforms that support them.
What you are doing is building clang "out of tree". Which is possible and even supported, but only really useful in certain circumstances. You'll need a previously built build of LLVM in some directory. You then set CLANG_PATH_TO_LLVM_BUILD to the directory containing the built LLVM files (this is not the source directory). But as I said, that's making things needlessly difficult.

Unable to build Boost libraries with GCC

I am using Windows 7 64-bit, and want to compile the non-precompiled libraries (specifically, I need Filesystem) from the command line (I do not use MSVC). I have MinGW, but read on the Boost website that MSYS shell is not supported, so I'm trying to compile the libraries from the Windows command prompt.
First of all, running bootstrap.bat results in the following error:
Building Boost.Jam build engine
'cl' is not recognized as an internal or external command,
operable program or batch file.
Failed to build Boost.Jam build engine.
Please consult bjam.log for furter diagnostics.
You can try to obtain a prebuilt binary from
http://sf.net/project/showfiles.php?group_id=7586&package_id=72941
Also, you can file an issue at http://svn.boost.org
Please attach bjam.log in that case.
Plus, there is not bjam.log file anywhere in the boost_root directory.
Disregarding this error, and trying to run the downloaded bjam.exe file, I get another error:

etc. with quite a lot of complaints. Setting the 'architecture' and 'address-model' options doesn't help.
Any suggestions?
#Andre
Following Andre's suggestion, I created minGW-bjam that was running for an hour and a half and built most of the libraries, but not the one I need at this moment: Filesystem.
Trying to compile only Filesystem, specifying version 2 with define="BOOST_FILESYSTEM_VERSION=2" and --disable-filesystem3 does not help. I get the following error:
gcc.compile.c++ bin.v2\libs\filesystem\build\gcc-mingw-4.5.2\debug\v3\src\operations.o

etc. with a lot of ...failed statements.
Any hints here?
It's easy. Just use "bootstrap.bat gcc" to select GCC
The bootstrap script assumes the msvc compiler is available. But you can build bjam by hand without the bootstrap script:
Step into the tools\build\v2\engine\src directory and call "build.bat mingw". It will create a bjam.exe. You can then put it in your %PATH% or perhaps in the root boost directory...
To be honest, I usually build bjam like this with the msvc compiler and use this "msvc-bjam" to build my mingw boost libraries.
So... the first part of the problem was solved by Andre's suggestion.
The second part was solved by setting the variable BOOST_FILESYSTEM_VERSION to 3 everywhere (the error above complains about incompatibility with what is set in file user.hpp). Although this is not the default option for Boost 1.45 that I'm using, it's the only thing that works (i.e. bjam wants to compile version 3 no matter what). So now I have version 3 of the filesystem library, and version 2 for all others, but that doesn't seem to be an issue for the moment.
I do have a problem with using Boost with OpenCV and Eigen libraries, though... off to the next challenge ;)
Since I can't comment yet, I want to add that I ran
bootstrap mingw
to generate b2 properly and then
b2 --build-dir="c:\boost_release" toolset=gcc --build-type=complete "c:\boost_release\stage"
The includes will be located at your boost root folder (boost_1_58_00/boost) and your binaries at the specified build folder.

Using Boost with Cygwin on Windows

This shoud be a simple problem for users more advanced than I am. :-)
How do I use the boost library with cygwin on windows?
I am programing with g++ using cygwin on a winxp machine.
I need modified Bessel functions of the second order, so I downloaded the latest version of the boost library and installed it in
'c:\cygwin\lib\boost_ 1_ 38_0\' folder.
I am trying to run the "example.cpp" program from the "getting started" section of their website:
http://www.boost.org/doc/libs/1_35_0/more/getting_started/unix-variants.html
I am compiling from the directory where I created the example file using a simple Bash shell command line: 'g++ -Wall example.cpp'
I keep getting the message:
"boost/lambda/lambda.hpp: no such file or directory"
I tried every possible combination of -L, -l, -I options in the command line to include the directory, to no avail. Also tried to add the folder in the PATH line of my windows system.
How do I link to the /boost directory and ALSO to all subdirectories? The header file 'lambda.hpp' is calling other header files in subdirectories.
You're probably not that familiar with C++ yet? It seems you are confusing terms.
C++ programs are built in two steps: compiling and linking. In the first step, each source file (typically called .cpp) is handled individually. Each .cpp file usually uses multiple headers, so the compiler first inserts those - literally. That's why it's called #include.
In the second step, the linker takes all the compiled .cpp files together and builds your final program. Some of those compiled .cpp's might have been bundled together before, in which the bundle is called a library.
Boost is a collection of headers and .cpp files. So, both compiler and linker might need to find the Boost directories. From your error message, it's clear that the compiler step is the problem. The linker does not need headers anymore.
The compiler will see the #include <boost/lambda/lambda.hpp> instuction. That means it needs to know where that first-level boost directory is found. I would guess at this point that the path would be /lib/boost_ 1_ 38_0/include (there's always the find / -name lambda.hpp shotgun appraoch)
If you are not utterly wedded to cygwin, you should take a look at http://nuwen.net/mingw.html which gives you a complete MinGW C++ installation with all the libraries (such as Boost) set up for you.
Edit: I should make it clear you can use this MinGW installation in addition to Cygwin, not as a replacement. Just make sure the MinGW bin directory appears in your PATH before the Cygwin one.
I think you need -I /lib/boost_1_38_0 - although that's a pretty unusual place to put it. You'll have to let us know how you installed it, did you just unzip it in the location you said, or did you run the makefiles? I assume that since you gave a windows path you didn't install it within cygwin - which you probably should do. The instructions in the getting started guide for unix should help - although don't download a prebuilt bjam - it needs to be built with cygwin.
But if you're not very familiar with cygwin (or unix in general) I think you might find it easier to use a native windows tool - as in Neil Butterworth's answer.
Thank you all for the information, it's a nice introduction to the use of libraries with cygwin.
Daniel was right. While any variation gives an error, the following line (using caps i) does the trick:
g++ -Wall -I /cygdrive/c/cygwin/lib/boost_1_38_0/ example.cpp -o example
I will also check MinGW in the next few days.
p.s. I simply downloaded and unzipped boost in that folder, but since I am only using header files I probably won't need to compile with cygwin. [The boost version included with cygwin was 1.33, which does not seem to have Bessel functions.]
This is on win7 cygwin64 g++ 5.4, and boost-1.64.7z on 2017-7. Google doesn't show any useful result for getting started for boost on windows (is boost out of fashion?).
By experimenting, I managed to compile and run a boost graph sample program as follows:
:: g++ 5.4 in c:\cygwin64
:: 7z extract boost download in c:\tools\boost\boost164
> set BOOST_ROOT=c:\tools\boost\boost164
