Hi guys,  
Just updated my Dynamic C from v10.66 to 10.72. I’m trying to compile my existing project from the 10.66 version that I previously do.  
This project got a .c source file (test.c) and a couple of .lib file (1.lib, 2.lib). But when I compile using the 10.72 version, it unable to find the 1.lib file. I try to find a place where I can put the path of my .lib file in the option but can’t seem to find it. Do you guys have any ideas what’s wrong?

You will need to add the folder where the lib files to the lib.dir file which resides in the Dynamic C 10.72 installation folder - default C:\DCRABBIT\_10.72
