Hi, For some time I've been trying to compile my framework for writing multimedia and 3d games in Guile Scheme on Windows/MinGW. The framework uses SDL library, and more details can be found here: https://puszcza.gnu.org.ua/projects/slayer
After many issues with compiling Guile Scheme on MinGW, I've finally managed to achieve it, and having build SDL, I proceeded to compile my framework. Although I did use the autotools to create a package, I know only superficially how it is supposed to work. Having ./configured my project, I managed to build the object files, but the final linking (performed by libtool) fails. It is invoked in the following way: ./libtool --tag=CXX --mode=link g++ -D_GNU_SOURCE=1 -Dmain=SDL_main -Ic:/mingw/msys/1.0/include/SDL -Ic:/mingw/msys/1.0/include/guile/2.0 -I/usr/local/include -Ic:/mingw/msys/1.0/include -Wall -Werror -mwindows -Lc:/mingw/msys/1.0/lib -lmingw32 -lSDLmain -lSDL -Lc:/mingw/msys/1.0/lib -lguile-2.0 -lgc -mwindows -Lc:/mingw/msys/1.0/lib -lSDL_image -lmingw32 -lSDLmain -lSDL -g -O2 -mwindows -Lc:/mingw/msys/1.0/lib -lmingw32 -lSDLmain -lSDL -Lc:/mingw/msys/1.0/lib -lguile-2.0 -lgc -mwindows -Lc:/mingw/msys/1.0/lib -lSDL_image -lmingw32 -lSDLmain -lSDL -o slayer.exe file.o font.o image.o input.o slayer.o symbols.o video.o -lSDL_ttf and the following error appears: c:/mingw/msys/1.0/lib/libmingw32.a(main.o): In function `main': e:\p\giaw\src\pkg\mingwrt-4.0.3-1-mingw32-src\bld/../mingwrt-4.0.3-1-mingw32-src/src/libcrt/crt/main.c:91: undefined reference to `WinMain@16' collect2.exe: error: ld returned 1 exit status However, I do manage to build the executable with the following command: gcc -o slayer.exe file.o font.o image.o input.o slayer.o symbols.o video.o -mwindows -lmingw32 -lSDLmain -lSDL -lSDL_image -lSDL_ttf -lguile-2.0 (there are still some problems caused by libguile in the runtime, but at least the linkign stage succeeds) I know that it might be a complicated issue, and the cause might lie on the side of either MinGW or SDL or pkg-config or autotools or mine, but I thought it might be best to ask you first. The project's files can be browsed here http://hg.gnu.org.ua/hgweb/slayer/file/bb4c97fd8329 Thanks in advance, M.
