[Llvm-bgq-discuss] compilation + core dump question

[Biddiscombe, John A.]

I've just experimented with clang on the new BGQ at CSCS, I followed the instructions for installing the relocatable rpms and am building hdf5 using cmake.

things compile ok (but note that the code so far is all C, not C++)  after I setup various paths to libs/includes etc,

when I try h5dump, I get

[biddisco at bbpbg1 hdf5_1_8_cmake]$ bin/h5dump -H /bbpfs/bgq/biddisco/build/hdftests/testing/hdf5-N0256-n64-t16384.sph
/bgsys/source/srcV1R2M0.14091/comm/sys/buildtools/pami/common/bgq/BgqPersonality.h:102:
/bgsys/source/srcV1R2M0.14091/comm/sys/buildtools/pami/common/bgq/BgqPersonality.h<102>
Aborted (core dumped)
now my suspicion is that I've linked to gcc versions of mpi and this is causing some trouble  - the link line looks like this ...

/tmp/bgclang/bin/clang
-L/bgsys/drivers/ppcfloor/spi/lib
-L/bgsys/drivers/ppcfloor/comm/gcc/lib
-L/bgsys/drivers/ppcfloor/comm/sys/lib
-g    CMakeFiles/h5dump.dir/h5dump.c.o CMakeFiles/h5dump.dir/h5dump_ddl.c.o CMakeFiles/h5dump.dir/h5dump_xml.c.o  -o ../../bin/h5dump ../../bin/libhdf5_tools_debug.a ../../bin/libhdf5_debug.a -lm -ldl -lrt -lmpich -lmpl -lopa -lpami -lSPI -lSPI_cnk -lpthread -ldl -lrt -lmpich -lmpl -lopa -lpami -lSPI -lSPI_cnk -lpthread

the include path contains
-I/bgsys/drivers/ppcfloor/comm/gcc/include

apart from the duplication of several libraries on the link line. Does anything look wrong? Meanwhile - I will try setting everything up using the xl paths and see I that changes anything. (Do I need to compile mpich myself using clang?)

Thanks hopefully.

JB
