Firefox has a terrifying build system and completely ungoogle-able error messages :(
good luck finding help for the "style" module in firefox that's not random CSS help stackoverflow posts...
I worked at NSCP back (way back) in the day, we could clean build on a desktop PPro in about 90 minutes, and it was not too difficult figure out what was going on where (even after the Xfe re-wrote everything in C++ without telling anyone).
It was still crazy, but it sounds like it still is and more. Yipes!
@danhugo somehow the codebase has both python2 and rust in it, I would call it crazy yes
And everything was in cvs without pserve, auto mounted on /m/src.
First day:
1. Do not cd /m/src
2. DO NOT cd /m/src
Someone did checkout into /m/src about once/week.
Such interesting times.
(root on all unix-like machines was pil/QED fwiw…)
