ELF: linking: Why do I get undefined references in .so files

Question

I\'m trying to build a program against wxWidgets, and I get a linker error. I\'d like to really understand what it means. The error is:

/usr/lib/libwx_baseu-2.8.         


        

Answer 1

I thought that .so files had all its symbols resolved, contrary to .o files that still need linking.

Shared libraries can be incomplete, that is OK.

do you know how I can get a list on undefined symbols in an ELF file

Use

nm -C -u libwx_baseu-2.8.so
