[mpich-discuss] question about running mpich2 on sol86

[Rajeev Thakur]

That's an MPI program. It won't build with just CC. Try a simple non-MPI program.
 
Also, if you want to use the Solaris compilers, make sure that the configure step picked up those compilers (look at the output of
configure). It usually picks up the GNU compilers by default. You can specify the compilers you want by setting the environment
variables CC, CXX, F77, and F90 before running configure.

I try to build the code with CC, it got link errors on sol86. I can build and run cpi.c using same makefile without problem (on
sol86).
 
chfcsx023:/home/shangliw/libraries/mpich2-1.0.8p1/examples/testcase_1 > make
@------------------------------------------
@=== Loading ./ems0.exe:   CC ...

Any suggestion?
 
Thanks

You need to specify the directory containing the C++ compiler libraries in the environment variable LD_LIBRARY_PATH or build MPICH2
without shared libraries. (The default build is without shared librares.)
 
Also try compiling and running a simple C++ program directly with the C++ compiler, not mpicxx.

Hi,
 
I try to build/run the example cxxpi.cxx on Sol86 using mpicxx. Compile seems OK. But when I run it, it shows error as:
 
chfcsx023:/home/shangliw/libraries/mpich2-1.0.8p1/examples/testcase_1 > mpicxx cxxpi.cxx
chfcsx023:/home/shangliw/libraries/mpich2-1.0.8p1/examples/testcase_1 > ls
a.out       cxxpi.cxx   cxxpi.cxx~
chfcsx023:/home/shangliw/libraries/mpich2-1.0.8p1/examples/testcase_1 > a.out
ld.so.1: a.out: fatal: libstdc++.so.5: open failed: No such file or directory

ld.so.1: a.out: fatal: libstdc++.so.5: open failed: No such file or directory
ld.so.1: a.out: fatal: libstdc++.so.5: open failed: No such file or directory
 
 
The same file can build/run on Sun4v/Linux without any problem. Would someone help me to understand what's wrong on Sol86?
 
Thanks
