#3 Won't build - undefined variables?

[Anonymous]

Hi! I'm using OS 10.7 (yes, I know, it's a Mac), so I tried to build v. 1.30 from the source. I open fourchan-dl.pro in Qt Creator, and when I try to build it, it fails with "'UPDATE_TREE' was not declared in this scope" on line 607 of mainwindow.cpp, "'APP_NAME' was not declared in this scope" on line 634, and "'APP_NAME' was not declared in this scope" on line 710. If these are not defined, why is everyone else able to build this program? What am I doing wrong? I'm not familiar with Qt at all.
