[HTCondor-users] Compiling htcondor on Gentoo

[Grant Goodyear <grant@xxxxxxxxxxxxxxxxx>]

I'm in the process of compiling htcondor on Gentoo Linux, and I ran into a cmake problem. It looks like -DPLATFORM gets set by looking at /etc/issue. Gentoo's /etc/issue file is, um, special. It's a blank line, followed by "This is \n.\O (\s \m \r) \t", followed by another blank line. That leads to the flags.make files having a very broken CXX_DEFINES line as cmake tries to put a linefeed into -DPLATFORM.ÂÂ The following patch seems to have worked:

Thanks for some awesome software!
