1 catastrophic error detected in the compilation of "../libs/thread/test/test_barrier.cpp".
Compilation terminated.

Maybe the build is setting threading=single and Boost.Thread doesn't force threading=multi or the selection in the config file doesn't takes in account the PGI compiler.

Thread: protect of threading=single by forcing threading=multi

to see if this is a Thread issue.

Just want to chime in and say that I see the same compiler errors compiling my application with pgCC. I hope this gets resolved, I'd like to use pgCC, but for now have to use GNU C++ due to this issue.

Thanks. reddell at uw.edu

boost/config/compiler/pgi.hpp defines BOOST_HAS_PTHREADS but not BOOST_HAS_THREADS, resulting in failure in the requires_threads.hpp header mentioned in the report.

As far as I can tell, there's no particular compiler flag needed to enable threading in current PGI versions. Simply hacking in a

#define BOOST_HAS_THREADS

in the pgi.hpp header seems to have done the trick for threading on my tested configuration (11.8).

It also works with pgi 11.9

Thanks for the analysis. I will see if we can add this soon.

It seems this is working now.
