Linking C main() to shlibs with Fortran sources using ccc/fort
Greetings,
I'd like to link some shlibs with some Fortran source to some C programs
using the Compaq compilers to compile everything. Trouble is, some of
the Fortran objects need symbols like for_write..., which are provided
by libfor.so, and that in turn needs this "MAIN__()" symbol, which is
*only* provided by an fort-compiled object file with a Fortran PROGRAM
statement, it's not in any of the libs which come with fort, nor in
for_main.o.
I've noticed that if the libs are static, linking works just fine, but
if I rebuild objects to shared libs using:
${LD} -shared -soname,$$LIBNAME.${SLSUFFIX} -o $$LIBNAME.${SLSUFFIX} *.o
then linking against the resulting shlibs fails with an undefined
reference to MAIN__() in libfor.so. Also, if I provide a C function like:
void MAIN__()
{
printf ("hello world\n");
}
then it links fine, but hello world is never printed, so the function is
never entered. I'd really like to not have to provide this bit of code
for this one arch/compiler combo...
Is there a way to do this?
Thanks,
