Permission issue on Lanka

[fredrikbk]

When I run taco on Lanka I get a permission error.

$ taco "a(i) = b(i) * c(i)"
/usr/bin/ld: cannot open output file /tmp/38jtrdwqmvy7.so: Permission denied
collect2: error: ld returned 1 exit status

You can try changing your TMPDIR environment variable to point somewhere else, e.g. somewhere in /data/scratch/. I can't replicate this error, even trying to run as a non-privileged user on Lanka.

Are you running on a compute node?

[fredrikbk]

No it's a dev tool so I was running on the login node. I'll try your prescription.

This works with the new TMPDIR. I'll mark it as closed, but these issues highlight why we really want a llvm library backend for our release.
