[Pypar-developers] PyPar installation

[Ole N. <ole...@gm...>]

Can anyone help out?
I don't understand where the -lopa comes from.

Cheers and thanks
Ole

Hi Ole,

We are trying to build PyPar on a couple of platforms, and are encountering
the same problem.

The two architectures are:  64-bit intels (one Linux, the other OS X Snow
Leopard).  The common
error we encounter in both is associated with this message:

gcc -pthread -shared build/temp.linux-x86_64-2.4/mpiext.o
-L/users/prl/rga112/mpich2-install-scucomp1/lib -lmpich -lopa -lpthread -lrt
-lopa' -o build/lib.linux-x86_64-2.4/pypar/mpiext.so
sh: -c: line 0: unexpected EOF while looking for matching `''

error: Command "gcc -pthread -shared build/temp.linux-x86_64-2.4/mpiext.o

-lopa' -o build/lib.linux-x86_64-2.4/pypar/mpiext.so" failed with exit
status 2

The main problem stems from this -lopa' element.  Grepping around your
source for "lopa" or "opa" didn't give us a clue how to fix this problem.

Additionally, on Snow Leopard, problems arise because PyPar is trying to
create a Universal Binary, when only x86_64 MPICH libraries have been
compiled, so we are looking for a way to remove the extra -arch switches.

We really would like to use PyPar in our project, so if you could please
advise us how to fix these problems, we'd be really grateful.

For reference, here's some version information on our software stack we're
using to build PyPar:

MPICH2-1.2.1
Python 2.6.1 (OS X)
Numpy 1.0.1 (current rpmforge repository version), latest SVN (OS X)
GCC 4.1.2 (Linux), 4.2.1 (OS X)
PyPar 2.1.0.66


Thanks and all the best...
