Bug ID: 101491
Summary: [11 regression] /usr/local/include/libgccjit++.h
conflicts between different GCC installations
Product: gcc
Version: 11.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: jit
Assignee: dmalcolm at gcc dot gnu.org
Reporter: gerald at pfeifer dot com
Target Milestone: ---
In the FreeBSD Ports Collection (and presumably similarly other distros)
we install different versions of GCC into the same prefix with
--program-suffix=
--libdir=
--with-gxx-include-dir=
which has been working very well for years.
Recently users reported that /usr/local/include/libgccjit++.h is
installed by both GCC 11 and GCC 12 at least, cf.
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=257060
Looks like this should go into a version-specific directory (such
as --with-gxx-include-dir= maybe?
