17:10 <Anarchos> how to link libnetwork.so to a lib.a ?

17:11 <jmairboeck> Anarchos: .a files (static libraries) are not linked at all. Linking occurs later when building an executable or a shared library (.so)

17:12 <jmairboeck> .a files are just an archive of object files (.o) with an index so that the linker can use them as input

17:13 <Anarchos> jmairboeck my lib.a file packs some .o files. one is referencening 'send' from libnetwork.so. but if i do 'nm lib.a | grep send' i got "U send" which means undefined

17:13 <jmairboeck> yes, but that is no problem for the lib.a. Consumers of lib.a will have to deal with that.

17:14 <Anarchos> makes sense

17:20 <jmairboeck> on Windows, using MSVC, you could specify libraries to link to via a pragma in the source code (auto-linking), but gcc doesn't support that. I'm not even sure if the ELF format would allow that.

18:04 <Anarchos> jmairboeck no trouble, i just add "-lnetwork" in LDFLAGS for the main program using the lib.a
