A followup — you can also set CHPL_HWLOC_MORE_CFG_OPTIONS in your environment
and do the hwloc rebuild like this:
export CHPL_HWLOC_MORE_CFG_OPTIONS=--disable-cuda
make -C third-party/hwloc clean all
This will be more convenient if you expect to be (re)building Chapel very much.

Ah, that looks like the hwloc build decided that CUDA was available and
configured hwloc to use it. But then when the qthreads build was running its
little test cases for configuration it didn’t know that it needed to link in
the CUDA library. Do you need CUDA for your Chapel work? If not then probably
the easiest way to solve this is to rebuild the Chapel hwloc package without
CUDA support, like this (from $CHPL_HOME):
make -C third-party/hwloc CHPL_HWLOC_MORE_CFG_OPTIONS=--disable-cuda clean all
Then just run your full Chapel make again. There’s no need to ‘make clean’
anything else — everything built before hwloc won’t depend on it and the things
built after it will rebuild appropriately.
If you do need CUDA with Chapel I expect I’ll have to pass you off to someone
else with experience making the two work together. I haven’t done that myself.

The last error reported is at line 4436

Before that at line 4142,

I am attaching the config.log.

Hi —
The last part of config.log just quotes all the settings. An error, if one is
reported, would be before that list of #defines. What you’re looking for would
be a place where it shows a (quite small) C test case, and then the result of
compiling and perhaps linking it.
