Perhaps it is redefineing the main function name to something else to include
it in a wrapper of its own. Example:
int usermain(int argc,char*argv[]); // prototype for your main
int main(int argc, char * argv[])
{
do setup stuff here
int value = usermain(argc, argv);
do closedown stuff here
return value;
}
Then in an include file you put in your program, but not the above...
#define main usermain
The above is probably wrong somehow, but you get the idea. I got this idea
from the Wine does this to wrap around the winmain function when compiling in
Linux, and I got this error when not including the Wine main fuction stub.
