Bug Fix
Description:
H5FC was failing on Copper (IBM P690). The reason: the xlf compiler
needs files to end in .f in stead of .f90. If you have .f90 files,
you need the "-qsuffix=f=f90" flag defined. This was defined for
compiling things via the "-c" option (to object files) but not for
straight compilation of a file.
I also noticed that the directory modules were being extracted from
was "." and "../src". H5FC would find these alright when doing a
"make check-install" but if Suzie User were to try this, it might
fail for her. Suzie would have to specify explicitly where to grab
these files.
Solution:
The solution to the problem was a bit more involved. I added a new
variable called "F9XSUFFIXFLAG" which is set to this value if the
machine needs it.
Added new variable called "FSEARCH_DIRS" which can be set to the
directories to find modules during compilation. The H5FC script knows
where to find the correct modules (it's in the lib/ directory), so it
uses the F9XMODFLAG to find them and not the FSEARCH_DIRS flag.
Platforms tested:
Modi4 (Fortran & Parallel)
Verbena (Fortran) C++ not needed since this is Fortran-only fix
Arabica (Fortran)
Copper (Fortran)
Ran "make install" and "make check-install" afterwards...
