Re: [OMPI users] which info is needed for SIGSEGV in Java foropenmpi-dev-124-g91e9686on Solaris

Hi Takahiro, Gilles, Siegmar, Thank you very much for all your fix. I don't notice about calling 'mca_base_var_register' before MPI_Init. I'm sorry for the inconvenience. Regards, Oscar El 27/10/14 07:16, Gilles Gouaillardet escribió: Kawashima-san, thanks a lot for the detailled

Kawashima-san, thanks a lot for the detailled explanation. FWIW, i was previously testing on Solaris 11 that behaves like Linux : printf("%s", NULL) outputs '(null)' vs a SIGSEGV on Solaris 10 i commited a16c1e44189366fbc8e967769e050f517a40f3f8 in order to fix this issue (i moved the call to

Siegmar, Oscar, I suspect that the problem is calling mca_base_var_register without initializing OPAL in JNI_OnLoad. ompi/mpi/java/c/mpi_MPI.c: jint JNI_OnLoad(JavaVM *vm, void *reserved) { libmpi = dlopen("libmpi."

Hi Gilles, I changed _dbg to a static variable, so that it is visible in the library, but unfortunately still not in the symbol table. tyr java 419 nm /usr/local/openmpi-1.9.0_64_gcc/lib64/libmpi_java.so | grep -i _dbg [271] | 1249644| 4|OBJT |LOCL |0|18 |_dbg.14258 tyr java 420
