bug#51518: native-compilation on OpenBSD

[Han Boetes]

Hi there,

I just tried building emacs with native compilation on OpenBSD-7.0 amd64 like this:

    export CC=egcc \
           CPP="ecpp" \
           CPPFLAGS="-I/usr/local/include" \
           LDFLAGS="-L/usr/local/lib"
    ./autogen.sh
    ./configure --without-makeinfo --without-x --mandir=/usr/local/man --with-native-compilation
    gmake

egcc (GCC) 11.2.0, is just gcc-11 which is traditionally installed as
egcc to avoid conflicts with the usually somewhat older gcc in base.


And it failed like this:

It looks like something is wrong with your installation of libgccjit.
I suggest to report this to the maintainers of the OpenBSD libgccjit
package.

OK, thanks for the tip. I recompiled gcc with the required options to
add gccjit, so I think I'll report the bug with the gcc team.

Thanks.  I see it was already solved, so I'm closing this bug report.
