The files in this package are needed to compile spring with MinGW.

There are two ways of using/setting-up mingwlibs.

1. The simple one (recommended for new users)

Have them in a folder named mingwlibs where you have extracted the spring source tarball or git repository. This way, SCons or CMake will automatically find the libs. Your directory structure should look like this:

AI/                 Spring AI source code
game/               Output binaries go here
installer/          Scripts to build installer
rts/                Spring source code
mingwlibs/          This package!
mingwlibs/bin/      Executables
mingwlibs/dll/      Dynamic link libraries
mingwlibs/include/  Header files
mingwlibs/jlib/     Java libraries
mingwlibs/lib/      Native import libraries

2. For multiple spring repositories

This is usefull if you have multiple spring repositories, and you do not want to maintain mingwlibs separately for each of them, or if you simple want to keep it away from the spring sources.

Just extract the archive anywhere you want it, eg like this:

C:\mingwlibs\bin
C:\mingwlibs\dll
C:\mingwlibs\include
C:\mingwlibs\jlib
C:\mingwlibs\lib

For the spring build-system to find the libs, you have to specify them in the configure step like this:

SCons

scons configure mingwlibsdir=C:\mingwlibs [other-options...]

CMake

cmake -DMINGWLIBS=C:\mingwlibs [other-options...]

Also included is reimp_new.zip, this contains reimp.exe which has been used to create MinGW32 import libraries for DevIL.dll, ILU.dll and ILUT.dll:

reimp DevIL.dll
reimp ILU.dll
reimp ILUT.dll

This creates libdevil.a, libilu.a, libilut.a and a number of .def files. You can throw away the .def files and move the lib*.a files to lib/.

il.h and ilu.h contain constructs which do not compile on certain GCC configurations so they have been fixed using the following command:

sed -i 's/(ILvoid)/()/g' mingwlibs/include/IL/{il.h,ilu.h}

Additionally il.h specifies __declspec(dllimport) __attribute__(__stdcall__) for its (and ILUs) functions, which causes (at least) GCC 4.3 to look for undecorated functions in the import library, which it will not find.

This is solved by the following modification:

--- il.h.orig   2007-04-17 23:00:59.000000000 +0200
+++ il.h        2007-04-18 13:02:55.000000000 +0200

The original il.h and ilu.h are included too as il.h.orig and ilu.h.orig.

imagehlp.h had an identical problem so it is included in this package. It should be picked up automatically because of the order of the include paths, ie. mingwlibs/include takes precedence over %MINGDIR%/include. It can be foudn in from w32api-3.9 on http://www.mingw.org.

  Note: since v9 downgraded to 2.1.10.2079 again because the particular 2.3.5 that was included showed small misaligned fonts (works fine with 2.3.5 on linux.) Do not know where I originally downloaded 2.1.10.2079
