Hi,
im working on a program which has to process data coming through the serial port then create an interface with SDL.I did 1 program to receive the data n process them n another program for the interface using sdl.They both work perfectly.Im started having problems when i wanted to merge the two programs.Here is a simplified version of the merged program n the errors.Thanks in advance.Im trying to fix this problem for about a week but cant.

i compile using gcc -o test test.c -lmingw -lSDLmain -lSDL -mwindows -lSDL_image

this is the errors i got cannot find entry symbol _winmainstartup;defaulting 00401000
ensuite d erreurs du genre /usr/lib/gcc-lib/i686/..libSDLmain.a(SDL_win32_main.o)...undefined reference to '__pctype! n many errors like that.

The problem is your linking -lmingw. You should be linking -lmingw32.
