| Subject: | PNG compile does not find zconf.h |
My smokers on linux (Debian sid) all refused to build Tk/PNG due to missing zconf.h. The reason is that zconf.h is in /usr/include/x86_64-linux-gnu/zconf.h and as such is found by gcc (4.7.3) even though it is included from /usr/include/zlib.h with
#include "zconf.h"
But it's not found by Tk/MakeDepend. The reason is in multiarch. The triplet x86_64-linux-gnu can be found with:
% gcc -print-multiarch
A tentative prove-of-concept fix works and is attached. At least the compilation is fixed that way. Some occasional test failures remain but have unrelated causes.
