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. It
should work, but I might have made a small error or two in the editing.
Please contact me if you have problems.
The makefile creates a shared object to which DX links as it runs. It
learns about the shared object by reading the mdf file; therefore, you must
run it like this:
dx -mdf mymodule.mdf
If your current directory does not contain the files example.mdf and
mymodule.so, you must expand the file name (above and in the sample mdf
file below) to include an appropriate path.
Cheers!
Kent
