Hi all.
I've got a .lib and .h file that I want to link to in my project - not sure where I'm going wrong though. The files are in C:\lib\TXF.
In Setup->Build Methods, I've added that directory to the INCLUDE and LIB sections. Then in the Package Organizer I've tried adding TXF.lib as a library, and as various other things, (leaving the When bit empty), but when I try and compile, I just get linker errors about the library's functions not being defined.
If anyone can point out what I might be missing or doing wrong, that'd be brilliant. Thanks in advance!

Project/Package organizer, click host package, right-click right big pane, choose "New Libraries".
You can look to e.g. Draw or Core package for example how the names of libraries are to be entered.

Thanks for the reply. Unfortunately I still can't get it to work. I've taken some screenshots so you can see my setup better:
I'm including C:\lib\TXF\TXF.h with a simple #include <TXF.h> which seems to work fine.
I'm trying to use the lib C:\lib\TXF\TXF.lib, and that's the bit that doesn't seem to work for some reason.
My error output is:
Linking...

File 'libcmt' not found.
File 'oldnames' not found.
File 'libcpmt' not found.
___main: duplicate

Thanks again for any help, much appreciated.
