Hi,
maybe this is already known, but I had to do a couple of modifications
to get ghdl-llvm compiled as the gcc version is 5.2 and llvm is 3.6
In the 'configure' script, I changed the test for llvm-config to llvm-config-3.5
This will be overwritten by a git reset --hard unless something is
done with the configure script upstream.
alternative is on the system level I created an update-alternative for
llvm-config
sudo update-alternatives --install /usr/bin/llvm-config llvm-config
/usr/bin/llvm-config-3.5 31
sudo update-alternatives --install /usr/bin/llvm-config llvm-config
/usr/bin/llvm-config-3.6 32
and then use sudo update-alternatives --config llvm-config to switch.
Next is that my default gcc version is 5.2 and there will be a
complaint about gnat1 is not present somewhere in the middle of the
build phase.
I simply fixed this by changing CC=gcc to CC=gcc-4.9 as I didn't
bother to create an update-alternatives for gcc as it seems this link
is set hard to gcc-5 by the package installer. I read a long debate on
whether update-alternatives is something which should be used for this
kind of redirection or not.
Maybe you simply need to add gnat for 5.2, if it does exist.
Maybe Tristan could change the use of the with-llvm option from
--with-llvm=/usr to --with-llvm=/usr/bin/llvm-config-3.5 to be able to
specify explicit which llvm-config to be used.
Yes, that's doable.
I don't know if gnat-5 can be used to compile ghdl. If I were to try,
apt would deinstall gnat-4.9 on my machine, and I didn't want to do
that as I was able to use gcc/gnat 4.9 and llvm 3.5 to build ghdl.
Tell us if it works.
Thanks,
Tristan.
