I'm not sure what's wrong, but I try to compile test.c: int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) { MessageBox (NULL, "Hello Win32", "First App", MB_OK); return 0; } using the command of: gcc -Zwin32 test.c -o test.exe and the results are: test.c:2: parse error before `WinMain' test.c:2: parse error before `hInstance' test.c: In function `WinMain': test.c:5: `NULL' undeclared (first use this function) test.c:5: (Each undeclared identifier is reported only once test.c:5: for each function it appears in.) test.c:5: `MB_OK' undeclared (first use this function) So I'm really having trouble... What could be wrong?
