Odd linking problem

[Vadi]

Can anyone spot what is wrong with this?

A bit out of ideas myself :/

You have to add all your custom .c files after main.c in the compile command as well...

[Zugzwang]

When linking in Linux, the order of the libraries is important. I would suggest trying to put "main.c" before "-ljson-glib-1.0", but I'm not sure if that helps.

Other .c's are build as libraries so it doesn't matter... changing the order didn't matter as well:


$ gcc main.c `pkg-config --cflags --libs glib-2.0 gthread-2.0 json-glib-1.0 gobject-2.0` -I./deps/Linux/ -I. -L./deps/Linux/ -L. -ggdb -Wall -o bot -lz -ldl

Turns out I had a bad copy of the library in the compile folder.
