Title: Underlinking - for extension creators
Post by: bmarkus on May 23, 2012, 02:09:42 AM

I had a strange issue few days ago compiling a program against libax25. Compilation was OK, no error messages nor warnings but running it (a Python module written in C) didn't start claiming a missing reference to inflateEND. Was also strange, that other applications using libax25 were OK without such message.,

Finally I found it was a so called underlinking issue. This is a good summary of the problem:

In my case the solution was to rebuild libax25 with the -lz linker switch.

It may affect other extensions too and the extension building process.

That's a bug in libax25 (library uses zlib but doesn't link it) then.

Yes, but google'g around found that it happenes frequently with other libraries too and makes people's life hard to fix. Just good to know.
