            Bug ID: 113188
           Summary: graphite-isl-ast-to-gimple.c: ‘isl_val_free’ was not
                    declared in this scope
           Product: gcc
           Version: 6.5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org
          Reporter: eyalroz1 at gmx dot com
  Target Milestone: ---

I'm struggling trying to build GCC 6.5.0 on a newer system: Devuan GNU/Linux
Excalibur (~= Debian Trixie). I'm using the following configuration:

./configure --disable-libsanitizer --disable-bootstrap --enable-languages=c,c++

and at some point, I get a couple of compilation errors about undeclared
identifiers; the error is quoted below.

Is there some way I could circumvent these? e.g. by disabling another component
or replacing a version of some tool/library?

--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The version of ISL that works with the version of GCC can be downloaded via
contrib/download_prerequisites or you can use --without-isl configure option
which will disable support to use ISL.  Anyways GCC 6.5 is no longer supported
so no patches are going to fix it.

Also bugzilla is not correct location for getting support of building older
versions of GCC which are no longer supported, the mailing list gcc-help@ is a
better place for that.

https://gcc.gnu.org/pipermail/gcc-patches/2017-February/469402.html I think was
the fix here ...
