Re: g++ fortran shared object error

Dear Toon:

It does not work on Sun Solaris 2.8.  I even tried it with gcc 3.3
version.  It works on Red Hat Linux (even with -lg2c flag).  Any clues?

Here is my test program test.f
       subroutine test(x)
       write (6,*) x
       return
       end

% g77 -c test.f -o test.o
% g++ 
% g++ -shared -o test.so test.o -lg2c
