I'm beginning to think I need to scrap everything and redo it from scratch. I've been manually adding libraries from GTK and gtkmm in the codeblocks compiler settings, when I finally see something else than missing header, I get this.

any ideas on how I can solve this? also, any tips on how to add these libraries to the standard path for libraries? doing this manually for every project will be a huge pain.
I solved it. instead of adding the header directories under the compiler's search directories. I added the following line:
`pkg-config --libs --cflags gtkmm-3.0`
to other options under both compiler and linker in codeblocks. that solved all conflicts and allowed me to run my test program finally.
