However, it seems to me, that you only addressed the linking problem. I am using another gcc-port (rsxnt) where I had no poblem in creating an import-library and linking to it (or, using LoadLibrary & GetProcAddress). I took the X11-libraries from Sergej, used only the DLL's and Headers and created my own Inport-Libraries, which I then linked to my rsxnt-gcc program. However, it crashed on every call of an X11-function. The real problem is to execute a function in a cygnus-made dll, that uses functions like 'malloc'. I think these functions are not correctly initialized when the dll is loaded by a non-cygnus program. So, my question is: Is your example still working if you use this function foo: int foo(int n) { int i; double *a=malloc(n*sizeof(double)); for(i=0;i
