I mean errors that are saying failed to load X.so. Then the user has to add
some paths to LD_LIBRARY_PATH. Although such problem can be fixed by adding
an export to the .bashrc, but I prefer to avoid that.

What problems are you referring to?

Basically, I want to prevent dynamic library problems (ldd) on a
distributed environment.
$ mpifort --showme
gfortran -I/opt/openmpi-2.0.1/include -pthread -I/opt/openmpi-2.0.1/lib
-Wl,-rpath -Wl,/opt/openmpi-2.0.1/lib -Wl,--enable-

To clarify:
1. Using --enable-static causes all the plugins in Open MPI
> You might have to remove -ldl from the scalapack makefile
I removed that before... I will try one more time
Actually, using --disable-dlopen fixed the error.
>mpirun --showme
$ mpirun --showme
mpirun: Error: unknown option "--showme"
Type 'mpirun --help' for usage.

You might have to remove -ldl from the scalapack makefile
If it still does not work, can you please post
mpirun --showme ...
output ?

Hi Gilles,
I noticed that /opt/openmpi-2.0.1/share/openmpi/mpifort-wrapper-data.txt is
created after "make install". So, I edited it and appended -ldl to
libs_static.
Then I ran "make clean && make all" for scalapack.
However, still get the same error!!
So, let me try disabling dlopen.
Regards,
not much difference from a performance point of view.
the difference is more from a space (both memory and disk) point of view
also, if you --disable-dlopen, Open MPI is rebuilt when a single
component is updated.
(without it, you can simply make install from the updated component
directory
I will try that. Meanwhile, I want to know what is the performance effect
of disabling/enabling dlopen?
Regards,
Mahmood

Yes, that is a problem :-(
you might want to reconfigure with
--enable-static --disable-shared --disable-dlopen
and see if it helps
or you can simply manuall edit
/opt/openmpi-2.0.1/share/openmpi/mpifort-wrapper-data.txt,
and append -ldl to the libs_static definition
Cheers,

>did you build Open MPI as a static only library ?
Yes, I used --enable-static --disable-shared
Please see the output
# mpifort -O3 -o xCbtest --showme blacstest.o btprim.o tools.o Cbt.o
../../libscalapack.a -ldl
gfortran -O3 -o xCbtest blacstest.o btprim.o tools.o Cbt.o
../../libscalapack.a -ld
Mahmood,
did you build Open MPI as a static only library ?
i guess the -ldl position is wrong. your link command line should be
mpifort -O3 -o xCbtest blacstest.o btprim.o tools.o Cbt.o
../../libscalapack.a -ldl
you can manually
mpifort -O3 -o xCbtest --showme blacstest.o btprim.o tools.
I added that but still get the same error. Please see the config file for
building scalapack
# cat SLmake.inc
CDEFS = -DAdd_
FC= mpifort -ldl
CC= mpicc
NOOPT = -O0
FCFLAGS = -O3
CCFLAGS = -O3
FCLOADER = $(FC)
CCLOADER = $(CC)
FCLOADFLAG
Sounds to me like you're missing a -ldl linker flag.
