Duplicate: https://bugs.gentoo.org/656970
This problem was first encountered by matplotlib users when compiling it with clang in 2011, apparently the old GCCs don't strictly enforce the rule. Just add a single "const" keyword will fix the problem, see this patch. https://github.com/mdboom/matplotlib/commit/3b0f5959bbea065b07538f9952ae520ab5a06c27
Created attachment 544868 [details, diff] fix const qualifier I ported the patch and applied it, now it compiles perfectly.
