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...

# set it. If CC is unset by time this script completes then configure
|

# will try `gcc' and `cc' in that order (perhaps some others too).
|

# Note: Code later in this file may depend on the value of $CC_BASENAME
|
|
# in order to distinguish between different compilers when
|
|
# deciding which compiler command-line switches to use. This
|
|
# variable is set based on the incoming value of $CC and is only
|
|
# used within this file.

# C Compiler and Preprocessor Flags

# ---------------------------------
|
|
#
|
|
# Flags that end with `_CFLAGS' are always passed to the compiler.
|
|
# Flags that end with `_CPPFLAGS' are passed to the compiler when
|
|
# compiling but not when linking.
|
|
#
|
|
# DEBUG_CFLAGS Flags to pass to the compiler to create a
|
|
# DEBUG_CPPFLAGS library suitable for use with debugging
|
|
# tools. Usually this list will exclude
|
|
# optimization switches (like `-O') and include
|
|
# switches that turn on symbolic debugging
|
|
# support (like `-g').
|
|
#
|
|
# PROD_CFLAGS Flags to pass to the compiler to create a
|
|
# PROD_CPPFLAGS production version of the library. These
|
|
# usualy exclude symbolic debugging switches
|
|
# (like `-g') and include optimization switches
|
|
# (like `-O').
|
|
#
|
|
# PROFILE_CFLAGS Flags to pass to the compiler to create a
|
|
# PROFILE_CPPFLAGS library suitable for performance testing (like
|
|
# `-pg'). This may or may not include debugging
|
|
# or production flags.
|
|
#
|
|
# CFLAGS Flags can be added to this variable which
|
|
# might already be partially initialized. These
|
|
# flags will always be passed to the compiler
|
|
# and should include switches to turn on full
|
|
# warnings. HDF5 attempts to be ANSI and Posix
|
|
# compliant and employ good programming
|
|
# practices resulting in few if any
|
|
# warnings.
|
|
#
|
|
# Warning flags do not have to be added to CFLAGS
|
|
# variable if the compiler is the GNU gcc
|
|
# compiler or a descendent of gcc such as EGCS or PGCC.
|
|
#
|
|
# The CFLAGS should contains *something* or else
|
|
# configure will probably add `-g'. For most
|
|
# systems this isn't a problem but some systems
|
|
# will disable optimizations in favor of the
|
|
# `-g'.
|
|
#
|
|
#
|
|
# These flags should be set according to the compiler being used.
|
|
# There are two ways to check the compiler. You can try using `-v' or
|
|
# `--version' to see if the compiler will print a version string. You
|
|
# can use the value of $CC_BASENAME which is the base name of the
|
|
# first word in $CC (note that the value of CC may have changed
