Subject: [OMPI users] problem with mpijavac in openmpi-1.9a1r27359
From: Siegmar Gross (Siegmar.Gross_at_[hidden])

I just installed openmpi-1.9a1r27359 in 64-bit mode. I used the following
command to configure the package. Unfortunately it doesn't work as expected,
because it still uses the 32-bit javac from /usr/local/jdk1.7.0_07/bin
so that I get an error when I try to run a Java program.

../openmpi-1.9a1r27359/configure --prefix=/usr/local/openmpi-1.9_64_cc \
  --libdir=/usr/local/openmpi-1.9_64_cc/lib64 \

  --with-wrapper-cflags=-m64 \
  |& tee log.configure.$SYSTEM_ENV.$MACHINE_ENV.64_cc

I have the following lines in config.log.

It was created by Open MPI configure 1.9a1, which was
generated by GNU Autoconf 2.69. Invocation command line was

javac is available in the 64-bit directory.

tyr openmpi-1.9-SunOS.sparc.64_cc 239 file /usr/local/jdk1.7.0_07/bin/sparcv9/javac
/usr/local/jdk1.7.0_07/bin/sparcv9/javac: ELF 64-bit MSB executable SPARCV9
  Version 1, dynamically linked, not stripped, no debugging information available

Why does configure still use the 32-bit version?

tyr openmpi-1.9-SunOS.sparc.64_cc 240 mpijavac -showme
/usr/local/jdk1.7.0_07/bin/javac -cp ... :.:/usr/local/openmpi-1.9_64_cc/lib64/mpi.jar

This way I get the following error.

tyr fd1026 244 mpiexec java -cp $HOME/mpi_classfiles HelloMainWithBarrier
Exception in thread "main" java.lang.UnsatisfiedLinkError:
  /.../openmpi-1.9_64_cc/lib64/ java: fatal:
  /.../openmpi-1.9_64_cc/lib64/ wrong ELF class: ELFCLASS64
  (Possible cause: architecture word width mismatch)
        at java.lang.ClassLoader$NativeLibrary.load(Native Method)

Is something wrong with my configure command? Thank you very much for any help
in advance.

Kind regards
