Hello IDLers,
I was trying to compile the following code(from Mike Galloy's book):
float mg_callex_total(float arr[], int *n) {
int i;
float total = 0.0;
for(i = 0; i < *n; i++) total+=arr[i];
return(total);
}
to create a shared object, but I got the following errors. Anyone knows why I got these errors? Thanks in advance.
Driss

I agree that supporting Windows is a pain. (Actually, one of my
"someday" tasks is to actually build my library on Windows. I don't
think there are any roadblocks, but I have no doubt that it will take me
days if not weeks or more to get it actually building.) Unfortunately, a
lot of people use it though, and I'm not aware of another Windows
compiler that is not even more pain. You would not believe that the
steps we had to take to prepare a machine to do Windows builds via
cygwin at a previous job.
Mike
