Hi, today I tried to track down the error which I reported for my small program (running on Solaris 10 Sparc).
tyr hello_1 121 mpiexec -np 2 a.out Process 1 of 2 running on tyr.informatik.hs-fulda.de Process 0 of 2 running on tyr.informatik.hs-fulda.de Now 1 slave tasks are sending greetings. ld.so.1: a.out: fatal: relocation error: file /usr/local/openmpi-1.8.2_64_cc/lib64/openmpi/mca_pml_ob1.so: symbol alloca: referenced symbol not found ... "alloca" is available. tyr hello_1 122 more x.c #include <stdio.h> #include <stdlib.h> #include <alloca.h> int main (void) { int *alloca_buffer; alloca_buffer = (int *) alloca (sizeof (int)); *alloca_buffer = 1234; printf ("value: %d\n", *alloca_buffer); return EXIT_SUCCESS; } tyr hello_1 123 cc x.c tyr hello_1 124 a.out value: 1234 tyr hello_1 125 I get the following output if I run my original program in "dbx". ...

Can I provide anything else? Thank you very much for any help in advance. Kind regards Siegmar
