CFLAGS overhaul
Description:
Modified the way configure handles CFLAGS.
(note: all changes also apply to FCFLAGS, CXXFLAGS, CPPFLAGS, and LDFLAGS).
1. The configure process will now always preserve a user's CFLAGS
environment variable setup. Any additional flags necessary for compilation
added at configure time will be passed into the Makefiles as AM_CFLAGS,
which is an automake construct to be used in addition to CFLAGS.
This will allow a user to have the final say, as CFLAGS will always appear
later in the compile line than AM_CFLAGS. Additionally, setting CFLAGS
during make will no longer completely erase all flags set by configure,
since they're maintained in AM_CFLAGS.
2. Additionally, where possible, flags previously being assigned directly
into CFLAGS (and thus propagating into h5cc) have now been redirected into
H5_CFLAGS, so they're used ONLY for compiling hdf5, and not embedded into
the h5cc wrapper script as well.
*Note that H5_CFLAGS ultimately is assigned into AM_CFLAGS for use in the
Makefiles. Complete description of changes and build process will be
included in a Configure Document that Elena and I are working on.
3. Removed unsupported config files. This includes:
config/dec-osf*
config/hpux11.00
config/irix5.x
config/powerpc-ibm-aix4.x
config/rs6000-ibm-aix5.x
config/unicos*
4. Modified configure summary to display additional values. Specifically,
appropriate AM_* variables are being shown, as well as H5_FCFLAGS and
H5_CXXFLAGS, which were for some reason not already present.
Tested:
- H5committest
- Tested on all THG / NCSA machines, using several combinations of the more
prominent configure options (c++, fortran, szip, threadsafe, parallel,
et cetera). (Thanks to Quincey for rysnc testing setup!)
- With regards to new automated testing, anything *necessary* for
compilation will be caught by the daily tests as it stands now. (i.e.,
if LDFLAGS is not properly set when szip is used, linking will fail).
Additionally, with regards to which flags get into h5cc, if any
*necessary* flags have been improperly removed, then daily tests should
fail during make installcheck. Additional machine-specific desired
behaviors and/or checks may have to be set up separately within the
daily tests, so this is something to work on.
Fix BZ #1583
Description:
The --enable-static-exec flag was broken. Configure was adding the
-all-static linker flag to an environment variable which was subsequently
never used. (looks like it was used in 1.6 Makefile.ins, but never
moved to 1.8's Makefile.ams when we added automake support).
To fix, I've added this environment varibale to the link lines of all the
tools. Now, when --enable-static-exec is invoked, it will correctly
generate statically linked executables in the installed bin directory.
Tested:
I've tested manually to ensure that the generated execs are static when
the flag is used and dynamic when not. I've also tested when szip is
used, as this was a use case mentioned in the bug report.
Also: ran full tests with make check on jam and smirom for good measure.
1. changed the -F flag option names to "BE and "LE" for big and little endian
2. added a more verbose usage message for these options
3. add a new test
4. add a make clean instruction to *.bin
new feature. h5dump output of binary data
Description:
a new switch -b FILE_NAME that dumps the contents of memory data to file FILE_NAME in binary form
new program binread.c that reads the contents of this file and outputs it to stdout
added a test for the h5dump shell script that does a run of -b
the binread.c program reads the data used in this run, usage is ./binread FILE_NAME
Solution:
Platforms tested:
linux
solaris
AIX
Misc. update:
Configuration feature
Description:
'make install' now tests both static and shared libraries if both are installed.
Solution:
Previously, shared libraries were only tested when static libraries were not installed.
Also cleaned up line in commence.am that was including HL library in all Makefiles.
Platforms tested:
mir (Makefile change only)
Bug fix - bugzilla #552
Description:
On Cray X1, trying to use : as an argument confused the system.
Solution:
Added a test in configure to see if : as an argument is bad.
If so, skipped the test.
Platforms tested:
mir, Cray X1 (change to configure only)
new feature
Description:
1) separated the HL library into "public" and "private" header files, with the same caracteristics as the basic library
2) added the public headers to hdf5.h (with a conditional include macro, defined in configure.in)
3) added the path to HL in all Makefile.am 's , because of the inclusion in hdf5.h
Solution:
Platforms tested:
linux 32, 64
AIX
solaris
with fortran and c++
(one packet table example fails)
Misc. update:
Bug fixes
Description:
This checkin fixes an occasional error on kelgia on sol during distclean.
It also causes test scripts to depend properly on the programs they're
supposed to be testing.
Solution:
The kelgia bug was due to some files being cleaned by automake and manually.
Removed the manual cleaning in src/Makefile.am.
Test script dependencies now need to be specified manually, since the
makefile can't guess what they test from their name. Currently all test
scripts in a given directory have a single list of dependencies--this was
easy and seems to be sufficient.
These dependencies are listed in the SCRIPT_DEPEND variable in the Makefile.am.
Platforms tested:
heping, mir, modi4, sol
Misc. update:
Makefile feature
Description:
'make check-clean' now cleans *.h5 files created by tests as well as
.log and .chkexe files.
Solution:
check-clean is now a separate target in its own right, which cleans less
than mostlyclean (check-clean < mostlyclean < clean < distclean).
Platforms tested:
mir, heping, modi4 (serial and parallel)
Bug fixes
Description:
A number of minor changes to Makefiles. Some files will now be cleaned
properly, some comments are more informative, etc.
Platforms tested:
heping, mir, modi4
Feature: tests now use parallel make and only run once
Description:
When make is invoked in parallel (using the -j option), several tests will
now be run simultaneously. This should speed up testing on a number of
systems.
When a test passes, it creates a foo.chkexe or foo.chksh file, which prevents
the test from running again unless the test or library changes.
Solution:
Most of the changes live in config/conclude.am. Added *.chkexe and *.chksh
files to the list of files to be cleaned at "make mostlyclean" time.
Parallel tests still run one at a time, but use the same make instructions
as serial tests.
Platforms tested:
mir, eirene, sleipnir, pommier, copper, modi4 (some errors occurred, probably
due to the test being run before updating hdf5. Will re-run tests after
checkin.)
Bug fix
Description:
Arabica exhibited strange errors when linker found wrong versions of
header files. This happened because include directories were
given to linker in the wrong order.
Solution:
Move include directories from AM_CFLAGS variable to INCLUDES
variable to put them before CPPFLAGS variable. Trust me, it works.
This bug may also have contributed to strange errors on other platforms
(kelgia?).
Platforms tested:
copper, sleipnir, arabica.
(h5dump broke while building on arabica, but this happened in
a clean checkout, too).
Configuration feature
Description:
HDF5 now uses automake to generate Makefiles
Solution:
Makefile.in files are now generated from Makefile.am files.
To reconfigure (after chaning a Makefile.am or configure.in):
/bin/sh bin/reconfigure.sh
Platforms tested:
Many
