Bug ID: 95012
Summary: [mingw/gcc10.1] mmapio.c:69:14: error: implicit
declaration of function ‘getpagesize’
Product: gcc
Version: 10.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libbacktrace
Assignee: unassigned at gcc dot gnu.org
Reporter: xantares09 at hotmail dot com
CC: ian at gcc dot gnu.org
Target Milestone: ---
when updating archlinux mingw-w64-gcc from 9.3.0 to 10.1.0
I noticed that libbacktrace fails to build because of an extra "-Werror"
present during the compilation of libbacktrace that was not here for previous
versions:
