I want to build myself standalone statically linked ffmpeg binaries for Windows from official git source code with MSYS2 environment tools. But every time I get .exe file dynamically linked to mingw libraries that crashes with "The application was unable to start correctly (0xc000007b)" error even if I put required libbz2-1.dll, libiconv-2.dll and libwinpthread-1.dll libraries in it's folder.
I'm running MSYS2 environment with
msys2_shell.cmd -mingw64
line, and use mingw64/mingw-w64-x86_64-gcc 8.2.1+20181214-1 compiler package. Then I run ./configure with
./configure --pkg-config-flags=--static --disable-shared --enable-static
line - the best options I have googled at all my efforts. Then proceed with general
make
make install
sequence.
As a result, I get binaries that run smoothly in MSYS2 environment itself, but when I run it from host Windows explorer or cmd, first of all it ask for libbz2-1.dll, libiconv-2.dll and libwinpthread-1.dll libraries and when I put them in binaries' folder, they crash with "The application was unable to start correctly (0xc000007b)" error.
I've asked about this case at official https://ffmpeg.zeranoe.com/forum/viewtopic.php?f=5&t=6439 forum but still have no response for already 5 days.
Regarding dynamic linking libraries somehow I got bandaid solution with removing *.dll.a files from mingw64\x86_64-w64-mingw32\lib folder. But it looks not very clean for me. I wish to know if it is possible to do static linkage with some compiler/make/linker parameters or with editing ./configure or Makefile files somehow?
Also 0xc000007b error still remaining.
I've managed to have desired result with media-autobuild_suite based on the same MSYS2 environment, so I know it is possible to do this somehow. But I'm very new to all this *nix things so don't understand it's bash script at all, not to mention it is pretty sophisticated by itself. The only thing I see it's producing correct ffmpeg executables running under native Windows environment not requiring dlls listed above.
According to all guides in internet I found at the moment, I should get standalone Windows executables with this toolset, but it just don't work and I'm stuck. Please, help.
I had the same problems. To solve it, I try to disable all external libraries.
My configuration:
--enable-static --enable-gpl --disable-w32threads --disable-autodetect
After compiling, I copy the libwinpthread-1.dll from /mingw64/bin to the binaries' folder. (you can use ldd ffmpeg.exe to print shared library dependencies)
ffmpeg.exe and ffprobe.exe can run successfully.

I've been trying this for over 5 days and I have no idea how to get this to work. I had successfully installed boost once, then I got my computer re-imaged and now it's just not happening. I have Windows 7 Enterprise, and 64-bit operating system.
I downloaded boost from here sourceforge
unzipped it into program files.
I then went to the VS 2013 Native Command prompt. Changed directory to boost tools/build
Ran bootstrap.bat
I then ran ./b2 address-model=64
but it did not give me directories for the compiler and the linker like last time.
I then ran ./b2 --prefix=C:\ProgramFiles\boost_1_58_0
but again nothing happens. I get the following errors:
Warning: No Toolsets were configured.
Warning: Configuring default toolset ""msvc"
Warning: If the default is wrong, your build may not work correctly
warning: Use the "toolset=xxxxx" option to overrride out guess
warning: for more configuration please consult
I have no idea why this worked the first time I had done this and why this isn't working now. Can someone please help me out. I know nothing about Unix but I need to install this so I can use the libraries.
I compile boost with both mingw (64 bit) and msvc 2013 pro. I have never in my life used the vs command prompt to build boost with msvc. Here are my commands to build 64 bit binaries on both toolchains.
First go into the boost folder and just double click bootstrap.bat. This should run and build bjam/b2. Nothing special required and doesn't matter what compiler this gets built with.
Then simply run, in a normal command prompt:
bjam.exe -a -j8 --toolset=msvc --layout=system optimization=speed link=shared threading=multi address-model=64 --stagedir=stage\MSVC-X64 release stage
Where -a forces rebuild all, -j8 means for the build to use 8 cores (adjust this based on your processor capabilities), toolset is obvious, layout means how to structure the naming of the output files, address-model is obvious, stagedir is where to output the built binaries (either relative or absolute path) and release stage is the type of build the system. See more here.
Same thing but using 64 bit mingw.
bjam.exe -j8 --toolset=gcc --layout=system optimization=speed link=shared threading=multi address-model=64 --stagedir=stage\x64 release stage
You can even go on to build additional libraries with a second pass tweaking your arguments. For example, after I've built the core libs with the above command, I run the following command to build in zlib and gzip support.
bjam.exe -a -j8 --toolset=msvc --layout=system optimization=speed link=shared threading=multi address-model=64 --stagedir=stage\MSVC-X64 --with-iostreams -s BZIP2_SOURCE=C:\dev\libraries\cpp\bzip2-1.0.6 -s ZLIB_SOURCE=C:\dev\libraries\cpp\zlib-1.2.8 release stage
Anyway that's just as an example. I linked to the full docs for the build system. Try building using these commands NOT inside a vs command prompt. If you still have problems then please post specific errors.
A note about MSVC
So, msvc compiler + boost supports a type of linking where it will automatically include additional libraries that it knows it needs. I believe boost does this by using the #pragma directive in headers. For example you might use boost::asio configured in such a way that it needs boost::system (for error codes and such). Even if you don't explicitly add boost::system library to the linker options, msvc will "figure out" that it needs this library and automatically try to link against it.
Now an issue arises here because you're using layout=system. The libraries are named simply "boost_" + the lib name, like "boost_system.dll". However, unless you specify a preprocessor define, this auto linking will try and link to a name like "boost_system_msvc_mt_1_58.lib". That's not exact as I can't recall the exact name, but you get the idea. You specifically told boost to name your libraries with the system layout (boost_thread, boost_system) etc instead of the default, which includes the boost version, "MT" if multithreaded, the compiler version, and lots of other stuff in the name. So that's why the auto linking feature goes looking for such a crazy weird name and fails. To fix this, add "BOOST_AUTO_LINK_NOMANGLE" in the Preprocessor section of your C++ settings in visual studio.
More on that here. Note that the answer here gives you a different preprocessor definition to solve this problem. I believe I ended up using BOOST_AUTO_LINK_NOMANGLE instead (which ended up working for me) because the ALL_DYN_LINK macro turned out to be designed as an "internal" define that boost controls and sets itself. Not sure as it's been some time since I had this issue, but the define I provide seems to solve the same root issue anyway.
I am trying to compile "xz-5.2.1" in MinGW/MSYS environment. I see the following errors:
#error UINT32_C is not defined and unsigned int is not 32-bit.
error: #error size_t is not 32-bit or 64-bit
I am not familiar with MinGW, could anyone shed some light on this? It looks like some macro definition are missing. Some header file missing?
ADD 1
The commands I used to compile the xz-5.2.1 are:
./configure
./make
The error screenshot:
Some background, I am following this link to compile the Tesseract-OCR library. And this is just one of the steps.
ADD 2
Based on the error message, I checked the sysdefs.h file. It contains the following content:
#ifdef HAVE_CONFIG_H
# include <config.h>
#endif
The above make output contains the -DHAVE_CONFIG_H, so I think the system header file <config.h> should be included.
But strange enough, I searched the C:\MinGW\include, there's no such file. So I GUESS this may have caused the undefined UINT_MAX warning at line 57. And then the UINT32_C is not defined error at line 58.
But I don't know why the system header file config.h is missing and where to get it.
ADD 3
I dig a bit about the GNU autotools. And luckily enough I find that the following commands can carry on my build process: (Though I am still not very sure why it works. All I know is that it may be related to portability.)
autoheader (this generates the config.h.in file)
./Configure (this generates the config.h file from the config.h.in file)
And now, my build process is blocked by another issue as below:
It seems this is a known issue. And another thread has addressed it.
(I will continue update with my progress.)
If you care for an easier way to handle this kind of dependency management or a general update on toolchain functionality, I strongly suggest switching to MSYS2 with MinGW-w64.
Both projects aim (and succeed) in bringing a better version of the original. MSYS2 comes with a large number of 3rd party libraries that you can easily install. MinGW-w64 allows for GCC with full C++11/14/... support and extended Windows API availability, along with some useful extensions and more up to date headers. You'll notice that most problems originating from system headers will have already been solved, either by the MinGW-Packages scripts below, or upstream (of either MinGW-w64 or the projects themselves).
For you specifically, I suggest the following steps:
Install and update MSYS2.
Open an MSYS2 command prompt (or the 32-bit or 64-bit command prompts if you plan on building 32-bit or 64-bit things) from the start menu entries. Install {32-bit,64-bit} MinGW-w64 GCC:
pacman -S mingw-w64-{i686,x86_64}-gcc
Install tesseract-OCR:
pacman -S mingw-w64-{i686,x86_64}-tesseract-ocr
and optionally the data files:
pacman -S mingw-w64-tesseract-ocr-osd mingw-w64-{i686,x86_64}-tesseract-ocr-eng
And you're done. Of course, you can still compile the various dependencies yourself, but why bother? If you really want to, you can start from the build scripts for the packages you can install in MSYS2, which are located here:
https://github.com/Alexpux/MINGW-packages
Just open the PKGBUILD files and you can see the build steps required. Note that all these scripts assume the dependencies have been installed within MSYS2.
Also note that the installed packages and compilers are all independent of MSYS2 as you'd expect: you can use it only as a tool to keep your development tree up to date, and build from any other Windows environment.
I am using msys2 Mingw (gcc 4.8.2 for i686 32-bit) for building Ghostscript 9.10. After running make, gs.exe was created successfully. Followed by that I ran "make so" for creating libgs library. Libgs.so, Libgs.so.9.10 were created which are of the same file size. But I found both of them to be PE executables. After renaming extension to .exe, they produced the same output as done by gs.exe. What I require is libgs.dll, libgs.a to be created, but instead "make so" creates libgs.so which is in fact a PE executable. I also tried using patch found on site:https://github.com/Alexpux/MINGW-packages/blob/master/mingw-w64-ghostscript/mingw-build.patch, but still the output remains the same. Has anyone been successful in this? Kindly help me.
I presume if you follow the steps taken in the build script connected to the patch you linked, everything will work out fine. I think most of it is just to make it use the "system"'s 3rd party libraries instead of those in the GS source. I'd guess running the configure command would do.
Alternatively, you could just download the MSYS2 base system from here, and do a pacman -Syu mingw-w64-i686-ghostscript. It should download and install the binary package without you having to build it yourself.
If you really want to build it yourself, download the PKGBUILD and patch, and run makepkg from the aforementioned MSYS2 shell and have that build it for you.
Have just completed testing of gs 9.15 built executables using the a patch
MINGW-packages-master.zip from https://github.com/Alexpux/MINGW-packages
Without implementing the zlib patch and PKGBUILD and using a MINGW 4.7.3 32/64
without by ghostscript used libs installed.
They did not work as is while using msys1 pathe'd up ahead of Windoze.
I simply edited the the MINGW Build and 32/64 bit type in makefile in
and set them to =1 there. and as i built without GTK defined in ./configure
SOC_LOADER_PLAIN manually to gs.c
Check the makefile after ./configure ahead of make or make so though , , .
All went well except for the COMPILE_INITS
mkromfs build that failed so I had to set that to =0 and build without that
feature. For me personally preferred as one can patch the gs fonts and libs
much easier.
The builds run as charm with full cpu optimisers implemented
only disabling gcse and guess-branch-probability, easily outperforming
the binaries provided by http://www.ghostscript.com/ by all means.
HPC !
the basic idea was, I wanted to generate the call graph in text format for several c files. After googling around for long time, i found cflow, which can deliver everything I want, but it is only runable in Linux or else. Then I began to search how to compile the cflow source files on the web to a exe file. I found MinGW which should be able to do the cross-platform compilation.
After installing the MinGW and the MSYS and running the usual commands "./configure; make; make install", I simply got an error that "mkdir" was not found. Actually. Actually I was wondering whether this is the correct way to compile the whole package.
Does anyone has an idea how I can build the cflow.exe correctly in Windows? If there is a tutorial or something like this, I will be very thankful.

Solution
Please try this Github repository "MinGW + MSYS build of GNU cflow 1.4" (For Windows).
https://github.com/noahp/cflow-mingw
It contains already compiled "cflow.exe",and an instruction about how to build cflow using mingw and msys.
Test
System Environment:Win 8.1 (x64)
1.I tested the "cflow.exe" downloaded from the github repository , and amazingly it worked!
2.I followed the mingw compiling instruction,and it successfully compiled "cflow 1.5".
Command:
bash configure
make
I was able to do that today. I'm using cygwin, after installing gcc, binutils, make and after downloading the gnu cflow.tar.gz, it was as easy as ./configure ; make ; make install.
From llvm.org I've downloaded llvm-2.6-x86-mingw32.tar.bz2 into c:\llvm and llvm-gcc-4.2-2.6-x86-mingw32-tar.bz2 into c:\llvm-gcc as well as setup a desktop shortcut the following batch file in c:\llvm-gcc which attempts to setup an environment for compiling via the llvm-gcc command line too:
#echo off
color 0E
echo Configuring LLVM environment...
set LLVM_LIB_SEARCH_PATH=%~dp0lib
set PATH=c:\llvm;%~dp0bin;%PATH%
Unfortunately, this setup gives the following error when trying to compile a simple hello world program:
C:\CDev\sandbox>llvm-gcc -o hello.exe hello.c
llvm-gcc: CreateProcess: No such file or directory
I've briefly looked through the LLVM binaries and it appears that the MinGW-based Win32 API and runtime files are already included. I also tried adding the MinGW DLL to c:\llvm-gcc\bin to no avail.
What have I missed in setting up the binary LLVM environment and GCC-based front end on Vista?
Thanks, Jon
Because the GNU/MinGW assembler 'as' was required by 'llvm-gcc' to generate the obj file. The problem can be solved by using:
Install GNU/MinGW binutils, extract the as.exe into c:\llvm-gcc\bin
Install a full MinGW package, add %MinGW%\bin your %PATH%
#rwallace is correct that one needs to also install MinGW's binutils along with the LLVM binary download. I've updated the LLVM documentation appropriately at
http://llvm.org/docs/GettingStarted.html#installcf
As far as I can tell, the answer is that the MinGW distribution supplied by LLVM is not complete, in particular, it doesn't come with the 'binutils' programs.
The recommended solution seems to be to download and install MinGW yourself. However, the MinGW download page seems to be saying this requires 10 different packages to be downloaded and installed separately.
The solution I tried today was to use the MinGW that comes with Qt, which does come in a single package; thus far, that appears to work.
It seems like it is looking for the base MinGW installation in C:\MinGW. I just had this error today using gcc.exe in msys. To solve it, I created a symbolic link from c:\msys to c:\MinGW and everything worked.
