Hi,

I am having trouble compiling a source files when OpenMP is enabled.

pgCC -o phaser/run/runMR_FTF.o -c -fPIC -DNDEBUG -O2 -DBOOST_ALL_NO_LIB -DBOOST_DISABLE_THREADS -mp -I/home/gaborb/phenix/current/boost -I/home/gaborb/phenix/current/iotbx/include -fPIC -DNDEBUG -O2 -DBOOST_ALL_NO_LIB -DBOOST_DISABLE_THREADS -mp -I/home/gaborb/phenix/current -Iinclude -I/home/gaborb/phenix/current/include -I/home/gaborb/phenix/current/tntbx/include -I/home/gaborb/phenix/current/ccp4io/lib/src /home/gaborb/phenix/current/phaser/run/runMR_FTF.cc -v

/tmp/pgCC8E00qacnN-s.s: Assembler messages:
/tmp/pgCC8E00qacnN-s.s:55341: Error: symbol `.LB27574' is already defined
/tmp/pgCC8E00qacnN-s.s:55838: Error: symbol `.LB27574' is already defined
<repeated many times>

The file compiles fine without “-mp”. However, when “-mp” is specified, and all the openmp pragmas are stripped out of the source, the same assembler error shows up.

OS: Fedora 9 Linux 32bit, with Intel quad core2 cpu.

Any suggestions?

Thanks, Gabor

Hi Gabor,

Can you please send an example of the code that causes this error to PGI Customer Server (trs@pgroup.com) and ask them to forward it to me?

Obviously, the compiler is doing something incorrectly. Though exactly what, I can’t tell without reproducing the error.

Thanks,
Mat
