As mentioned earlier, system is Fedora 25 with gcc 6.2.1.

Any ideas?

Hi Gaius,

After getting your tarball and restarting combine-trees..configure..make I still see same situation and same errors as result. 4.7.4, and

Question: Did your patches address this gnu_inline issue, ie is it expected to see this fixed? I think this patch is supposed to fix it:

I will try this again later, with this patch included.

gcc_5.2.0_gm2 is current development branch. master branch changes are
in April, and gcc_5.2.0_gm2 - today.

Ok, I pull this, I switch to mentioned branch, then:

cd scratch/source/gm2
mkdir build
cd build
../gcc-versionno/configure --enable-languages=c,c++,gm2

make SHELL=/bin/bash
….
….
And then this:

Some things are, I don’ know - unclear?

1. combine-trees pulls gcc-4.7.4
2. last lines of its execution mention lot of patches to gcc-4.7.4
3. again this failure (last console snippet)

Hi Dragiša,

ah thanks - yes I need to overhaul combine-trees and friends.
At present, every time I git commit a change a script on
floppsie.comp.glam.ac.uk will rebuild the tarballs for any branch
necessary.

You should be able to pull the changes from:

 git clone http://git.savannah.gnu.org/r/gm2.git

or alternatively download a tarball from

 http://floppsie.comp.glam.ac.uk/download/c/gcc-5.2.0+gm2-git-latest.tar.gz

regards,
Gaius
