Dear OS X folk,
Background: I’m compiling projects which require OpenMP. These crash when linking to \
the omp libraries included by Apple under llvm, so, wanting to install omp-friendly \
gcc
Simon[1] has a long list of possible binaries, mostly at gcc 4.2.4
It also has a warning against the hpc[2] binary “they won’t work correctly!”
But hpc have gcc 4.7, updated for Lion as recently as Feb 2012 (10.7 Lion only) and \
explicitly suporting OpenMP.
I downloaded and installed this binary: All running fine…
So questions:
1. Is it the case that the hpc binary “doesn’t work correctly” for R?
2. Is a recommended install that is up to date and robust?
3. Compiling the OpenMx package, all the compile steps run fine, but the make fails \
on one of the final load checks as follows:
** testing if installed package can be loaded
Error in dyn.load(file, DLLpath = DLLpath, ...) :
unable to load shared object \
'/Users/tim/Library/R/2.14/library/OpenMx/libs/i386/OpenMx.so': \
dlopen(/Users/tim/Library/R/2.14/library/OpenMx/libs/i386/OpenMx.so, 6): Symbol not \
found: _GOMP_parallel_end Referenced from: \
/Users/tim/Library/R/2.14/library/OpenMx/libs/i386/OpenMx.so Expected in: dynamic \
lookup
Any clues why “_GOMP_parallel_end” not found?
many thanks
tim
