[Llvm-bgq-discuss] bug report

Thu Apr 3 05:55:07 CDT 2014

Dear list,

I was recompiling hwloc just now (for the nth time) and clang died on me with this output (below)

Knowing that a new clang is due imminently (he says hopefully), I won't spend a lot of time worrying about this.

Note. I tried compiling on the login node but then hwloc gives the wrong output, so I tried compiling on the ION where I want to use it and then it gave this.
Note 2. If I ./configure on the ION itself it fails with a C compiler can't create exe, in the config.log it has some guff about link error (int main) ...

yours

JB (PS. Is the new version going to be soon? - I'm only posting this bug because it gives me a convenient excuse to ask that!)
