Installation on Ubuntu 16.04 #5

Closed domluna closed 8 years ago

Following up a discussion from Gitter, installation on Ubuntu 16.04 doesn't work. The issue appears to be with the liblzma version.

More details have been discussed in the upstream repo at Marqt/ViZDoom#75. I think we should keep this here for reference until it's fixed upstream.

Update from the discussion upstream, the issue is solved by changing the default linker from ld to ld.gold.

Credits go to @vmonaco

Check which linker you're using:

ls -l /usr/bin/ld

Install gold and set as default:

apt-get install binutils-gold
update-alternatives --install "/usr/bin/ld" "ld" "/usr/bin/ld.gold" 20
update-alternatives --install "/usr/bin/ld" "ld" "/usr/bin/ld.bfd" 10

Switch between gold and GNU linker:

update-alternatives --config ld
