Setting up the build environment on Windows

Assuming Windows XP 32. We will use MinGW to build the libraries and application and MSYS as a working environment.

The distinction between MinGW and MSYS is very important: MinGW is a set of compilers and libraries you use to build Windows applications, while MSYS is a GNU environment similar to (and, in fact, based on) Cygwin. You can not use MSYS libraries in your Windows application.

Doesn't really matter which one. Certified binaries of The Real McCoy are available at http://www.collab.net/downloads/subversion/ (command-line only) if you have an account (or are willing to register). There are other (non-certified) sources such as SlikSVN (http://www.sliksvn.com/en/download, command-line only) and TortoiseSVN (http://tortoisesvn.net/downloads, with Windows Explorer integration, which is really neat).

Download and the latest automated installer from http://sourceforge.net/projects/mingw/files/Automated%20MinGW%20Installer/ and run it. Ask for the current version (not previous or candidate). Select these components and these components only: base tools, g++ compiler, g77 compiler.

As of 2009-11-20, the current MinGW version is 5.1.6, which includes GCC 3.4.5.

tip: move the installer into an empty directory before starting it; it will download all the MinGW distribution files into that directory.

At this point, you may want to download bsdtar from http://sourceforge.net/projects/mingw/files/MinGW%20Utilities/basic%20bsdtar/bsdtar-2.7.900a_r1628-20091110/ and install bsdtar.exe as /mingw/bin/tar. It supports a wider range of archive formats and compression algorithms than GNU tar, and automatically detects which one to use.

Download the MSYS installer from http://sourceforge.net/projects/mingw/files/MSYS%20Base%20System/ and run it (you will need administrator privileges). Accept the default answer to all questions.

As of 2009-11-20, the latest MSYS version is 1.0.11.

Let's see if our C compiler works:

$ which gcc
/mingw/bin/gcc.exe
$ gcc --version
gcc.exe (GCC) 3.4.5 (mingw-vista special r3)
Copyright (C) 2004 Free Software Foundation, Inc.

$ cat >hello.c
#include <stdio.h>
int main(void) { printf("Hello, C world!\n"); return 0; }
^D
$ gcc -o hello hello.c
$ ./hello.exe 
Hello, C world!

And C++:

$ which g++
/mingw/bin/g++.exe
$ g++ --version
g++.exe (GCC) 3.4.5 (mingw-vista special r3)
Copyright (C) 2004 Free Software Foundation, Inc.

$ cat >hello.cc
#include <iostream>
int main() { std::cout << "Hello, C++ world!" << std::endl; return 0; }
^D
$ g++ -o hello hello.cc
$ ./hello.exe 
Hello, C++ world!

And Fortran 77:

$ which g77
/mingw/bin/g77.exe
$ g77 --version
GNU Fortran (GCC) 3.4.5 (mingw-vista special r3)

$ cat >hello.f
      PROGRAM HELLOW

      END
^D
$ g77 -o hello hello.f
$ ./hello.exe 
 Hello, Fortran world!

Or rather, in our brave GNU world, flex (http://downloads.sourceforge.net/project/mingw/MSYS%20flex/flex-2.5.35-1/flex-2.5.35-1-msys-1.0.11-bin.tar.lzma) and bison (http://downloads.sourceforge.net/project/mingw/MSYS%20bison/bison-2.4.1-1/bison-2.4.1-1-msys-1.0.11-bin.tar.lzma). In addition, flex requires the GNU regex library (http://downloads.sourceforge.net/project/mingw/MSYS%20regex/regex-1.20090805-1/libregex-1.20090805-1-msys-1.0.11-dll-1.tar.lzma). Download and install as usual.

Microsoft's tool for creating installation packages: http://sourceforge.net/projects/wix/files/. Ironically, it does not come with its own installer.
