Hi Gilles,
now I can answer the second part of your email. "LDFLAGS='-m64 -mt -z
noexecstack'"
didn't help.

Siegmar,
did you try to run
execstack -c /usr/local/openmpi-1.10.2_64_cc/lib64/libmpi_java.so.1.2.0
and did this help ?
the message suggests you link with -z noexecstack,
you added this to your CFLAGS and not LDFLAGS
would you mind trying to configure with LDFLAGS='-m64 -mt -z noexecstack' and
see if it helps ?
Cheers,
Gilles

Hi,
I've successfully built openmpi-v1.10.1-140-g31ff573 on my machine
(SUSE Linux Enterprise Server 12.0 x86_64) with gcc-5.2.0 and
Sun C 5.13. Unfortunately I get warnings if I use my cc version
running a Java program, although I added "-z noexecstack" to
CFLAGS. I used the following commands to build the package.
mkdir openmpi-v1.10.1-140-g31ff573-${SYSTEM_ENV}.${MACHINE_ENV}.64_cc

Now 3 processes are sending greetings.
Greetings from process 1:
message tag: 3
message length: 4
message: loki
...
Does anybody know how I can get rid of the messages or can somebody
fix the problem directly in the distribution? Please let me know if
you need anything else. Thank you very much for any help in advance.
Best regards
Siegmar
