Hi Folks,
Does anybody have any experience building shared libraries on the Cray XE6?
I've been wrestling with HDF5 installation on a Cray XE6 today, and am
having particular trouble getting the configure system to handle the
sensitive needs of the Cray compilers.
For example, to create a dynamically-linked executable, this requires the
"-dynamic" flag to the Cray C compiler.
cc -o test.exe -dynamic -lfoo
I don't actually need hdf5 to build dynamic executables for me, what I
really need is it to not fail when trying to build the test executables.
There's a configure option that seems to allow the building of static
executables,
AC_ARG_ENABLE([static_exec],
[AS_HELP_STRING([--enable-static-exec],
[Install only statically linked executables
[default=no]])],
[STATIC_EXEC=$enableval])
This then goes on to enable:
LT_STATIC_EXEC="-all-static"
This variable is used in quite a few places in the build tree, but it
doesn't appear to be used at all in the ./test directory. Is this
deliberate? The executables built here are susceptible to the same errors
as elsewhere.
My current inclination is to simply patch the flags in the ./test
subdirectory to the (more appropriate) "-static" build flag, but I'm not
very familiar with building a shared version of HDF5 on supercomputers.
Any advice on how to move forward here would be appreciated.
Cheers,
Aron
