Bug ID: 85298
Summary: relocation errors on windows when linking C code to
libstdc++ built with weakrefs
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: rkitover at gmail dot com
Target Milestone: ---
Apologies in case this is a known issue, I was encouraged to report this to gcc
proper.
See discussion here:
https://github.com/Alexpux/MINGW-packages/issues/1580
The issue happens when linking C code such as ffmpeg to other libs that use
libstdc++, then you get a bunch of "relocation truncated to fit" error
messages.
Disabling weakrefs in libstdc++ fixes the issue, as is done in this patch:
https://github.com/Alexpux/MINGW-packages/blob/master/mingw-w64-gcc/0016-disable-weak-refs-in-libstdc%2B%2B.patch
The issue still affects gcc 7.3.0 and starts with gcc 6.0 .
