Bug 328971 – sys-process/htop can not be cross compiles, because /proc/stat and /proc/meminfo can not be tested for existence

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Johannes Krude 2010-07-19 15:04:57 UTC]

./configure for htop fails when cross compiling. ./configure can not detect wheter /proc/stat and /proc/meminfo exist. ./configure needs these answers in env vars.

I updated the ebuild to make it work, the relevant lines are

Committed to ebuild for 1.0.1 (slightly in different syntax but essentially the same)
