I am trying to build Boost.Python according to the instructions on the official website.
My OS is Windows 7 64-bit, the compiler is MSVC11, the boost is 1.54.
=================== Install Boost ==================
To install basic Boost, I downloaded the boost library from its website, unzip it to my local disk. The path is C:\local\boost_1_54_0.
=============== Install Boost.Python ===============
I then find that Boost.Python need to be built separately. So I followed the Boost.Python instruction.
=============== Install Boost.Build ================
And at stage 3.1.2, Boost.Build is required. So I, again, followed the steps and install Boost.Build at C:\local\boost_1_54_0\BoostBuild, and added C:\local\boost_1_54_0\BoostBuild\bin into the Path enviroment variable.
Then I am stuck at stage 3.1.3 and 3.1.4, where the instruction says
3.cd into the libs/python/example/quickstart/ directory of your Boost installation, which contains a small example project.
4.Invoke bjam. Replace the “stage“ argument from the example invocation from section 5 of the Getting Started Guide with “test,“ to
build all the test targets. Also add the argument “--verbose-test” to
see the output generated by the tests when they are run.
On Windows, your bjam invocation might look something like:
C:\boost_1_34_0\…\quickstart> bjam toolset=msvc --verbose-test test
I've typed the command line that the instruction told me and I am sure that I am in the right directory. However, there is no bjam or b2 in the quickstart folder (they are at the root direcroty of Boost and C:\local\boost_1_54_0\BoostBuild\bin).
I even tried to copy these two files to the quickstart folder, but doesn't work at all.
I am not very familiar with the Windows management mechanism, thus am not sure if the Path is the key to my question. I guess after I added the bin folder to the PATH, the OS will automatically link my bjam toolset=msvc --verbose-test test to the bjam in the C:\local\boost_1_54_0\BoostBuild\bin folder?
Can anyone help me with this? :)
1.) Unzip boost_1_55_0.zip
2.) Prepare to use the Boost Library Binaries
Go to the boost_1_55_0 root directory and open a command prompt and type following commands:
Bootstrap
3.) Find user-config.jam:
Type following in the command prompt:
ECHO %HOMEDRIVE%%HOMEPATH%
4.) If the user-config.jam is in your homedrive directory please change it there as followed:
ATTENTION:
The .jam language rates a “whitespace” as a separation of arguments!
# -------------------
# MSVC configuration.
# -------------------
# Configure msvc (default version, searched for in standard locations and PATH).
# using msvc ;
# Configure specific msvc version (searched for in standard locations and PATH).
using msvc : 10.0 : C:\\app\\tools\\MSVisualStudio2010\\VC\\bin\\cl.exe ;
….
# ---------------------
# Python configuration.
# ---------------------
# Configure specific Python version.
# using python : 3.1 : /usr/bin/python3 : /usr/include/python3.1 : /usr/lib ;
using python
: 2.5 # Version
: C:\\app\\tools\\Python25\\python.exe # Python Path
: C:\\app\\tools\\Python25\\include # include path
: C:\\app\\tools\\Python25\\libs # lib path(s)
: <define>BOOST_ALL_NO_LIB=1
;
5.) Build the Libraries AFTER configuration!!
Go to the boost_1_55_0 root directory and open a command prompt and type following commands:
.\b2
6.) Copy the user-config.jam to \boost_1_55_0\libs\python\example\tutorial
7.) Go further to \boost_1_55_0\stage\lib\
Rename libboost_python-vc100-mt-gd-1_55.lib to boost_python-vc100-mt-gd-1_55.lib and copy it to
\boost_1_55_0\libs\python\example\tutorial
8.) Now you should have all of these files in the \boost_1_55_0\libs\python\example\tutorial directory
hello.cpp
hello.py
user-config.jam
Jamroot
boost_python-vc100-mt-gd-1_55.lib
bjam.exe
9.) Open a command prompt in \boost_1_55_0\libs\python\example\tutorial
And type following command:
bjam
10.) After successful building..
You should have this file in the directory:
hello_ext.dll
rename this file to:
hello_ext.pyd

I installed the latest Cygwin on my Windows 7 machine: version 2.893 (64-bits). I made sure I included cmake, i.e. I was able to add several packages by running the Cygwin net release setup program again, after doing the first installation. I then tried to use cmake and made sure I invoked it from the bin directory:
user008#L0147816 /bin
$ ./cmake
CMake Error: Could not find CMAKE_ROOT !!!
CMake has most likely not been installed correctly.
Modules directory not found in
//share/cmake-3.6.2
Usage
cmake [options] <path-to-source>
cmake [options] <path-to-existing-build>
Specify a source directory to (re-)generate a build system for it in the
current working directory. Specify an existing build directory to
re-generate its build system.
Run 'cmake --help' for more information.
I don't know where the build directory could be. I'm relatively new to Cygwin. I hope somebody has found a solution for getting cmake installed and working properly under Cygwin.
This looks cmake 101.
Assuming you want to just build a software download from somewhere
eg gl2ps:
# choosing a test area
$ cd /tmp
# downloading source
$ wget http://geuz.org/gl2ps/src/gl2ps-1.4.0.tgz
# expanding source code
$ tar -xf gl2ps-1.4.0.tgz
$ ls gl2ps-1.4.0-source/
CMakeLists.txt COPYING.LGPL gl2ps.h gl2ps.tex gl2psTestSimple.c
COPYING.GL2PS gl2ps.c gl2ps.pdf gl2psTest.c README.txt
# preparing a build area
$ mkdir build
$ cd build
# invoking cmake and pointing to the source directory
$ cmake ../gl2ps-1.4.0-source/
-- The C compiler identification is GNU 7.3.0

Instead for learning how to build with cmake, go to
https://cmake.org/cmake-tutorial/
Here a solution I just found.
Let's name 3 directories:
{cygwin64-path}/bin/: cmake.exe is here.
{cygwin64-path}/usr/share/: cmake module directory (such as cmake-3.20.0) is here.
{cygwin64-path}/share/: cmake.exe trying to find cmake-module-directory here, but it doesn't exist.
It's wired because cygwin install cmake-module-directory in {cygwin64-path}/usr/share/, but cmake.exe looks for the directory in {cygwin64-path}/share/.
So solution is simple. Each one below works.
METHOD 1: Create the directory {cygwin64-path}/share/ and copy all relevant directories and files from {cygwin64-path}/usr/share/ to the new directory.
METHOD 2: Create a Symbolic links {cygwin64-path}/share/ to {cygwin64-path}/usr/share/.
In windows 10 Administrator cmd.exe: mklink /J share usr\share and all works.
Or use WSL or Cygwin64 Terminal: ln -s usr/share share
I am trying to install the openCV library for Python however I am new to CMake and have run into some trouble after having cloned the repository in ~/opencv.
I've made a build directory in it with the mkdir command however once inside it when trying to set CMake options in it.
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local
I get prompted with the following error:
CMake Error: The source directory "/Users/eDen/opencv/build/CMAKE_INSTALL_PREFIX=/usr/local" does not exist.
It seems you aren't making the right directory, some Mac OS X installations doesn't include /usr/local/. You can make the directory using, if it's not already created, with:
sudo mkdir /usr/local/
But you say you want to use OpenCV with Python. I recommend you to obtain an already compiled copy unless you need some advanced features not available in the compiled version, like Qt integration or CUDA programming. But these features are included in the arguments of the cmake command.
Instructions on how to obtain OpenCV from Homebrew repository, this page explains the process. Basically, you install Homebrew, then Python, configure it and install some dependencies.
As Tsyvarev mentioned in the comments, you need to specify the path to source directory (i.e. where the main CMakeLists.txt file exists) at the end of your command. So, supposing you are now in the build directory, the final cmake command would be as follows:
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
I have the last argument as .. but still get the error.
In my case, there is a bad whitespace in the above arguments. So the last .. is ignored.
I am trying to include ZMQ sockets in a Go app but both zmq4 and gozmq (the referred ZMQ binding libraries for Go) are giving me problems. I would like to understand why zmq4 specifically isn't importable on my system.
I am running a Windows 8 system and I used the windows installer from the ZMQ website for version 4.0.3. I am primarily concerned about getting zmq4 set up and here is the result of my "go get" query on the github library's location:
> go get github.com/pebbe/zmq4
# github.com/pebbe/zmq4
polling.go:4:17: fatal error: zmq.h: No such file or directory
compilation terminated.
This issue is not alleviated by cloning the Github repository - the error remains the same.
I know the issue has to do with the C library zmq.h that is located in the "include" folder of my ZMQ installation, but whether the dependency is held up by a pathing issue or an external tool issue is a mystery to me.
A similar error has come up in regards to node.js and is the solution I see others referred to, outside of node scripting, but it was unsuccessful in my case.
I've so far included the path to the "include" folder in my PATH environment variable and previously placed zmq.h inside of the zmq4 top-level folder. I don't have much of an arsenal otherwise to understand this problem because I am new to C and C-importing packages in Go
I wanted to do the same thing, but on Windows 7, and here is what I had to do.
Since the Go bindings are using cgo to integrate with zeromq, you need zeromq built with gcc. There are no pre-built binaries, so you'll have to build them yourself, with mingw or similar, but this process is easier than it may sound, and nicely described on the zeromq site.
As #photoionized pointed out, C_INCLUDE_PATH and LIBRARY_PATH need to be set when building the Go bindings.
(In my case, I ran into a problem when compiling libzmq with IN6_ADDR not being defined. The only solution I found was, inspired by this issue, to manually add the line #include <in6addr.h> to the windows.hpp file.)
The Windows installer version of ZeroMQ won't work with zmq4, you need to compile from source with gcc, I recommend using MSYS2.
Install and update MSYS2 following the instructions from
http://sourceforge.net/p/msys2/wiki/MSYS2%20installation/
Start the mingw32_shell.bat or mingw64_shell.bat based on Go arch (32bit or 64bit)
pacman -S mingw-w64-(x86_64|i686)-toolchain make (x86_64 for 64bit, i686 for 32bit)
cd into zeromq src folder (C:\ path starts with /c/ inside the shell)
./configure
make
make install
CGO_CFLAGS=-I/usr/local/include CGO_LDFLAGS=-L/usr/local/lib go get github.com/pebbe/zmq4
Copy the following dlls and put them next to your go program (.exe):
/usr/local/bin/libzmq.dll
/mingw(32|64)/bin/libgcc*.dll
/mingw(32|64)/bin/libwinpthread*.dll
/mingw(32|64)/bin/libstdc++*.dll
Here's updated steps for #user2172816's MSYS2 solution:
Install and update MSYS2 following the instructions from http://sourceforge.net/p/msys2/wiki/MSYS2%20installation/
Start the mingw32_shell.bat or mingw64_shell.bat based on Go arch (32bit or 64bit)
pacman -S mingw-w64-(x86_64|i686)-toolchain make (x86_64 for 64bit, i686 for 32bit)
Add C:\msys64\mingw64\bin to your Path (pkg-config is there)
Restart the msys2 shell to get the new Path
Download and unzip libsodium source: https://github.com/jedisct1/libsodium/releases
cd into libsodium folder (C:\ path starts with /c/ inside the shell)
./configure --build=(x86_64|i686)-w64-mingw32
make
make install
Add /usr/local/lib to PKG_CONFIG_PATH (export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig)
cd into zeromq src folder
./configure --build=(x86_64|i686)-w64-mingw32
Add
#ifdef ZMQ_HAVE_MINGW32
#include <winsock2.h>
#include <windows.h>
#include "netioapi.h"
#endif
To the top of src/tcpaddress.cpp
make

Copy the following dlls and put them next to your go program (.exe):
/usr/local/bin/libzmq.dll
/mingw(32|64)/bin/libgcc*.dll
/mingw(32|64)/bin/libwinpthread-*.dll

maybe? /usr/local/bin/libsodium-*.def
An updated answer using MSYS2.
Install MSYS2 MSYS2 installation guide.
Make sure to choose the correct installation 32bit or 64bit.
Open the appropriate shell MSYS2 MinGW 64-bit or MSYS2 MinGW 32-bit. All further steps assume you are using this shell.
Update packages following instructions at the installation guide.
Install libtool pacman -Sy libtool.
Download zmq source code to a location of your choice.
Navigate to the zmq source folder.
To generate the configure file, run the autogen tool by running ./autogen.sh.
In the probable case that step 8 fails:
Find the file at fault (probably version.sh).
Replace line endings by (replace file by the actual filename).
cp file file.bak
tr -d '\r' <file.bak> file
If this fails you'll have to dive in the code and find the problem.
Run the configure tool ./configure.
In the probable case of failure. Comment out empty else clauses in the configure file.
Add Go to Path: PATH=${PATH}:<go bin directory>.
Install Go Package: CGO_CFLAGS=-I/usr/local/include CGO_LDFLAGS=-L/usr/local/lib go get github.com/pebbe/zmq4
To install ZMQ in windows: Problem in Installing Golang ZMQ for windows - fatal error: czmq.h: No such file or directory
First of all, install the msys64. Download the software from https://www.msys2.org/ and install it on C:\msys64.
Then add C:\msys64\mingw64\bin to PATH environment variable of the windows.
Then run the following commands (in CMD) one by one.
pacman -Su
pacman -S --needed base-devel mingw-w64-x86_64-toolchain
pacman -S base-devel gcc vim cmake
pacman -S mingw-w64-x86_64-libsodium
pacman -S mingw-w64-x86_64-zeromq
Finally, run the Go install command:
go get github.com/pebbe/zmq4
Finished.
I was trying to build Boost library from source for MinGW. The Boost website says no guarantee but there seem to be people done it successfully. However I couldn't find much instructions on the web.
I updated the title to better reflect my problem right now.
======================== Original post ==============================
I downloaded Boost 1.53.0, unzipped it and cd to the folder in MinGW shell. It failed at the very first step I tried:
$ ./bootstrap.sh mingw
Building Boost.Build engine with toolset gcc...
Failed to build Boost.Build build engine
Consult 'bootstrap.log' for more details
Inside the bootstrap.log the errors are:
builtins.c:33:23: fatal error: sys/wait.h: No such file or directory
compilation terminated.
execunix.c:17:26: fatal error: sys/resource.h: No such file or directory
compilation terminated.
fileunix.c:98:17: fatal error: ar.h: No such file or directory
compilation terminated.
Please help! Thanks!
================== End of original and beginning of update =====================
Update: I found this detailed instruction on line:
http://vijay.axham.com/blog/478/building-boost-binaries-on-mingw
I followed it along and now got stuck in the final build step that is supposed to take a long time but I got an error instead:
$ b2 --build-dir=$BOOST_BUILD_DIR --prefix=$BOOST_INSTALL_DIR toolset=gcc variant=release link=static threading=multi runtime-link=static install 2>&1 | tee $BOOST_BUILD_DIR/build.log
error: Unable to find file or target named
error: 'boost/tr1/tr1/bcc32'
error: referred from project at
error: '.'
but the directory is there (it should be since it's just extracted from the zip file)
$ ls boost/tr1/tr1/bcc32/
array.h random.h regex.h tuple.h type_tra.h unordere.h
Getting closer but still need help! Thanks!
OK I got it working. The trick was to download the tar.bz2 file, not the zip file from sourceforge (specifically http://sourceforge.net/projects/boost/files/boost/1.53.0/). Even though both the zip and the tar.bz2 files are listed under the same file folder for the same version of Boost, the contents are different. There are some missing folders in the zip file, and the line ending conventions of the compressed files are different. At any rate after I downloaded and extracted the tar.bz2 file. I followed the instructions given here:
http://vijay.tech/articles/wiki/Programming/Cpp/Boost/BuildingBoostOnMinGw
and successfully built the Boost library from source using MinGW shell (mintty to be exact). There were some failures but probably not important: has_icu_test, has_iconv, has_icu_obj, has_icu64_obj, .masm. At the end it says
...failed updating 2 targets...
...skipped 3 targets...
...updated 10623 targets...
Hope this will help others in the future.
Do not use bash. Build it using cmd.exe.
bootstrap.bat gcc
Compiler executable should be on PATH.
Do not use bash. Build it using cmd.exe as described below:
Install MinGw on your system. I recommend using the same bit system as your processor is. Then set the path in System Environment to the bin folder which contains g++, ... (Compiler executable should be on PATH.) files. Now you are ready to go.
For obvious reasons, start a fresh terminal (cmd.exe), don't use the already open terminals that doesn't know your new setting.
Download boost, the latest stable release, unzip it and in the command window follow the path too the main directory of the extracted boost.
Run this command: bootstrap mingw
Run this command afterwards, which will install in the folder you select as your destination.
b2 install --prefix=c:\boost\custominstallationfolder\gcc toolset=gcc
Like said above, but more specifically for me compiling boost-1.54 with gcc-mingw-4.8.1
Using a Windows shell (cmd.exe) navigate to root of boost directory directory then
bootstrap.bat gcc
b2.exe toolset=gcc
Noob question ahead...
I'm trying to install SWIG on Windows. According to the INSTALL document, I have to
cd to the directory containing the package's source code and type ./configure to configure the package for your system.
I tried the command in both the root directory and in the /CCache directory (these are the only ones that have the configure and configure.in files), however, the shell reports back that
C:\swigwin-2.0.4>./configure
'.' is not recognized as an internal or external command,
operable program or batch file.
What am I missing?
no installation is needed. you just have to set the environment variable to point to the "swig" 's executable which is under the root directory of swig
On the SWIG site, you can download for example the swigwin-2.0.7 zip directory for windows's swig. unzip it in a directory of your choice for example on "C:\Program Files" directory if you want. After this, you have the swig executable in the "C:\Program Files\swigwin-2.0.7" directory: "C\Program Files\swigwin-2.0.7\swig"
you have to set now the environment variable "path" to point to this swig exec: add for this the "C:\Program Files\swigwin-2.0.7" path to the "path"variable according to my example; that is all you need to use swig on windows. You can now play with swig so, open a prompt "cmd" and just type "swig --help" on this prompt you can see a list of the differents options you can use with swig.
If you d'ont have visual c++, you can use for example codeblock, that is my case so the link below could be a help for you : http://wiki.codeblocks.org/index.phptitle=Adding_support_for_non_C/C%2B%2B_files_to_the_build_system
The page http://www.swig.org/download.html has a specific download for Windows with a pre-built version of swig.exe. You can download it and avoid the hassle of compiling swig by yourself.
If you really need to, you can consult the file Doc/Manual/Windows.html that contain Windows-specific instructions to build SWIG.
Finally, to answer your specific question, the syntax
./configure
is a UNIX-style command that means 'execute the program named configure in the current directory' (the dot)
On Windows, you would type
.\configure
or even simpler, as all files are executable on Windows, only
configure
... BUT this will not work as the said 'configure' script is a bash script that will not run in a Windows shell.
Download Miniconda.
Then follow this guide and do: conda install -c anaconda swig
