Dear Anders,
I am very interested in your post, since I was trying (nearly) the same
thing. 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<n;i++) a[i]=i;
i=(int)a[n-1];
free(a);
return i;
}
