Kent, First of all, thank you. It compiled !! After compilation, I got hello.mdf hello.c and hello.o hello2dx.c hello2dx.o hello.so
Thus, I started dx with dx -mdf hello.mdf I could find Hello tool and could place it in VPE. But when I execute the visual program, error occurred and it reads 'ERROR:Hello: Operation not implemented: function does not exist" When I try to compile with -o hello, it just doesn't like it :( Thank you in advance, Juw Won On Mon, 2003-03-03 at 11:04, Kent Eschenberg wrote: > --On March 03, 2003 01:34:53 AM <[EMAIL PROTECTED]> wrote: > > This question is about module programming. > > When I try to compile even a simple file, gcc throws an error. > > And it looks like whenever I use DX function, it cannot find the > > reference of that function. > > Dear Juw, > > I've included (below) examples of what I have been using with Linux and DX. > It has been edited to remove things that I don't think you would need.
