Bug ID: 87182
Summary: libbacktrace does not use GCC own zlib
Product: gcc
Version: 8.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libfortran
Assignee: unassigned at gcc dot gnu.org
Reporter: vigerske at math dot hu-berlin.de
CC: ibuclaw at gdcproject dot org
Target Milestone: ---
The configure of libbacktrace checks for -lz without considering the build of
zlib in ../../libz (the one that GCC builds). That is, libbacktrace introduces
a dependency on the systems zlib in libgfortran even if --with-system-zlib has
not been set.
It seems that this was introduced with rev 253275:
https://gcc.gnu.org/viewcvs/gcc/trunk/libbacktrace/configure.ac?r1=253095&r2=253275
Rev 263320 does some cosmetic change
(https://gcc.gnu.org/viewcvs/gcc/trunk/libbacktrace/configure.ac?r1=256169&r2=263320),
but doesn't fix this issue (imho).
