Improvement.
Description:
Moved the "-Wall -g -O0" to DEBUG_CFLAGS so that they are
used only in development mode.
Platforms tested:
Tested in TG-NCSA since this change affects ia64 platform only.
Misc. update:
Bug fix
Description:
It uses the value of $ARCH as a gcc option but the linux clusters
at NCSA define $ARCH as environment variable with values that are
not a valid compiler option. That caused the configure to fail
because it was not able to compile at all.
Solution:
Change ARCH to lower case $arch (convention dictates environment
variables are upper cases.) Also preset $arch to null and do not
honor any pass it values.
Platforms tested:
Attempted to run h5committest but sol was failing due to /tmp
filled. Copper failed in parallel test but that could be a
system problem since it was totally loaded. Verbena failed in
h5diff which has nothing to do with the change.
Tested in TG_NCSA (gcc and ecc)--both failed in h5diff. Again,
nothing to do with the change. So, it is safe to commit this
change.
Misc. update:
Code cleanup
Description:
Reduce compiler warnings on SGI IRIX
Platforms tested:
FreeBSD 4.10 (sleipnir)
SGI IRIX6 (Cheryl's machine)
Too minor to require full h5committest
Code cleanup & addition
Description:
Add new warnings for gcc 3.4.x
Re-work production mode compile flags to work better.
Platforms tested:
FreeBSD 4.10 (sleipnir)
h5committest
Description: One of the CFLAGS -D__GNUC__ caused problem for ecc 8.
It was added because there was conflicting definition for int64_t
in /usr/include/stdint.h and /usr/include/sys/types.h when ecc was updated to
7.1. Since those two files have been updated, the problem is no longer there.
Solution: take the flage -D__GNUC__ out.
Platforms tested: ecc on titan, the only place concerned.
Slight improvement.
Description:
Show directory name at the beginning and ending of running
make check in a directory. Together with the time stamp,
it will be easier to see how much time it takes to run all
the tests in one directory.
Platforms tested:
Eirene only.
Misc. update:
Bug fix
Description:
Fix build on sparc64 platform for FreeBSD by modifying the config/gnu-flags
to not insert '-march=i686' on non-Intel platforms. (This change allows HDF5
to run correctly on all five of the main FreeBSD platforms... :-)
Platforms tested:
FreeBSD 4.9 (sleipnir)
h5committest not run since it's a FreeBSD-specific fix.
Bug fix
Description:
Update threadsafe flags for FreeBSD and allow C++ to be built with
threadsafe enabled.
Platforms tested:
FreeBSD 4.9 (sleipnir) w/C++ & thread-safe
Code cleanup/bug fix
Description:
Fix configuration files to allow 64-bit compilation of the library with
a 64-bit version of zlib.
Solution:
Moved important compiler flags settings from CC macro to CFLAGS macro.
Instead of setting CC (F9X, CXX) environment variable for compiling for 64-bit
code, users should just set the CFLAGS (FFLAGS, CXXFLAGS) to -q64.
Updated INSTALL file to reflect this change.
Platforms tested:
IBM p690 (copper) w/parallel, FORTRAN, C++, srcdir.
Platforms specific - h5committest does not apply.
improvement.
Description:
Created an entry for 2.96 and added -Wno-long-long to the CFLAGS
to suppress the thousands of 'long long' warnings because we are
using it and we know it is not in the C89 standard.
Platforms tested:
Eirene.
Bug fix
Description:
Update gcc 3.4 flags to reduce optimization level to the same settings
as for gcc 3.0-3.3 due to code generation bugs at higher optimization levels.
Platforms tested:
FreeBSD 4.9 (sleipnir)
Purpose: Maintenance
Description: Added Fortran support for MAC OS X
Solution: This port was tested only for IBM XL Fortran compiler
version 8.1 Beta.
Few things to remember:
1. do not use AFS to build Fortran; compiler
for some reason cannot find *.mod files that
were successfully compiled.
2. Fortran Library can be built only with --disable-shared
--enable-static flags.
Platforms tested: pommier, h5committested (it is amasing, but iot works
really nicely! Albert, Thank you!)
Misc. update:
Bug fix
Description:
Add special-case handling to floating-point conversion tests to avoid
problems with denormalized values on Cray T3E & T90 platforms. (Still not
working on Cray SV1, but at least it's closer).
Solution:
Detect denormalized values and don't try to operate on them on the Crays.
Platforms tested:
FreeBSD 4.9 (sleipnir)
Cray T3E (hubble.cray.com)
Cray T90 (gypsy.cray.com)
Bug fix
Description:
Fix problems building on Debian Linux when Intel's "ecc" compiler is
not available.
Platforms tested:
Eyeballed - very trivial patch from user.
Update DEC compiler support
Description:
Updated DEC/Compaq compiler detection to handle DEC->Compaq switchover
in compiler version string.
Also, copied v5.x compiler flags to V6.x compiler flags and included the
-ieee and -misalign flags necessary for correct floating-point support.
Platforms tested:
Pittsburgh Alpha Cluster (lemieux.psc.edu)
Bug Fix
Description:
CFLAGS wasn't using user-set values in one instance
Solution:
Changed CFLAGS="..." to CFLAGS="$CFLAGS ..."
Platforms tested:
Arabica
(the machines affected)
Misc. update:
"bug fix", sort of.
Description:
now that stream-vfd is on by default, it does not work for Tflops.
Set it to no by default.
Platforms tested:
Tested in Tflops.
Misc. update:
Bug fix
Description:
Reduce optimization level from -O3 to -O for gcc 3.*, since it seems to
be generating bad code for the atomic type conversions now...
Platforms tested:
FreeBSD 4.9 (sleipnir)
Linux 2.4 (eirene, verbena)
h5committest not necessary, this is a GNU-only change.
Bug fix
Description:
The MPI_File_set_size() routine on ASCI Red is not able to extend files
so that they are larger than 2GB.
Solution:
Add an extra macro which controls whether MPI_File_set_size() can handle
>2GB offsets or if our "older" way of reading a byte, then writing a byte at
the appropriate offset should be used.
Platforms tested:
FreeBSD 4.9 (sleipnir)
h5committest
Bug fix
Description:
The "prefix?=..." is not recognized by all make commands. Even some
older gmake do not recognize it. The result is that "make install"
failed for many platforms (AIX, Solaris 2.7, HPUX 11, ...) because
when they tried to install at $(prefix)/lib, it becomes /lib since
$(prefix) is not defined.
Solution:
Restore it back to the previous
prefix=...
Platforms tested:
h5committested.
Also ran in-place build using vendor make in kelgia, arabica
and copper.
Misc. update:
Bug fix
Description:
"prefix" variable was always being set, instead of only being set if the
user hadn't set it yet.
Solution:
Changed "prefix=<foo>" to "prefix?=<foo>".
Platforms tested:
FreeBSD 4.8 (sleipnir)
Checked in gmake manual to make certain syntax is the same (it is).
Purpose:
Bug Fix
Description:
Changes needed to make "pmake" work on Modi4.
Solution:
Needed to add some null macro defines in the commence.in files.
Needed to remove a dependence on LIBH5TEST in the fortran make
since LIBH5TEST isn't used in the fortran stuff.
Platforms tested:
Modi4 (small change)
Misc. update:
Improvement
Description:
RUNPARALLEL is setup with default value when --enable-parallel but only if
CC is not set.
Solution:
set RUNPARALLEL to default value of using poe when --enable-parallel
or when an MPI compiler (e.g. mpcc_r) is used.
Platforms tested:
Copper for both 32 and 64 bit, serial and parallel.
(32bit parallel had a hang problem in configure which is a different but
known problem.)
Note that one still need to setenv AR "ar -X64" for 64bit configure.
Misc. update:
Speed up
Description:
Cache the settings of all number types to save configure time.
Reduced configure time by a whopping 40% (11m to 7m :-)
Platforms tested:
Sasn100 only (janus frontend.)
Replaced the individual setting of gcc flags with the combined
gnu-flags file.
Platforms tested:
Tested in modi4 with different combinations of gcc. No needed to
run three platforms tests since this is for irix machines only.
Misc. update:
Code cleanup
Description:
Remove special optimization and debugging flags for obsolete versions of
gcc.
Platforms tested:
FreeBSD 4.8 (sleipnir)
h5committest not needed.
Feature
Description:
Sometimes the total build process take a long time, especially in
parallel systems. Need some idea if some times are taking way
too long to process.
Solution:
Added timestamps marking the beginning and ending of tests in
one directory. This gives a rough idea of how much time the
tests use.
Platforms tested:
Tested only in Eirene since this is just a makefile thing and only
involve a simple command like echo and date.
Misc. update:
Code Cleanup
Description:
Warning messages were being produced by the "make" program because
the "docdir" was being specified twice as a target in the generated
Makefiles. This is because the "EXAMPLESDIR" was also defined as
"docdir".
Solution:
Made "EXAMPLESDIR" unique for C, Fortran, and C++ in the commence.in
file and removed EXAMPLESDIR from the Makefile.ins
Platforms tested:
Dangermouse (only affects make system, not code).
Misc. update:
Improvement
Description:
Added an explanation of using $HDF5_PARAPREFIX for Parallel tests.
Platforms tested:
h5committested (using sol instead of arabica) plus eirene(pp).
Misc. update:
Purpose: Maintenance for T3E
Description: Cray updated T3E to run unicosmk2.0.6.X
Configuration failed.
Solution: Created new unicosmk2.0.6.X files in the config and fortran/config
directories and added them to MANIFEST
Platforms tested: Cray T3E
Misc. update:
Initial pass for gcc3.3 support
Description:
Added section for gcc 3.3+ and cleaned up the gcc 3.2+ section a little.
Platforms tested:
FreeBSD 4.8 (sleipnir) w/gcc 3.3 snapshot
Triple check unneeded.
Bug Fix
Description:
The compression stuff includes the "zlib.h" header file. This
file on the SP machine was including another file which would
#define const as nothing if the compiler wasn't a Standard C
compiler.
Solution:
Included a flag to make the compiler into an ANSI compiler.
Platforms tested:
Blue (Only affects powerPC computers)
Misc. update:
Purpose: Catching up with 1.4 branch
Description: 1.5 didn't have unicos10.0.X configuration files
for both C and fortran.
Solution: Added the files
Platforms tested: CRAY T90IEEE
Misc. update:
Feature (bug fix)
Description:
Added a new configure file specifically for the IA64 platform
in which ecc and efc are the default compilers.
Also added all the Fortran special setup in the fortran version
Platforms tested:
no h5committest since this is a IA64 platform stuff.
Tested in Titan.
Misc. update:
MANIFEST Updated.
Bug fix
Description:
test/dtypes failed badly when -O is used. Trying to recompile test/*
code without -O did not eliminate the errors. So, the failure is
deep in the hdf5 library.
Solution:
For now, removed '-O' from $PROD_CFLAGS so that enable-production will use
no optimization. Need to find out what exactly trigger the errors.
Platforms tested:
Did not do h5committest because this is an AIX configure change only.
Tested it in Copper. Need to test it on other offsite machines.
Misc. update:
Updated release_docs/RELEASE.
New test feature
Description:
The various virtual file drivers (multi, family, core, ...)
are not tested automatically. One would have to do it by hand
by setenv HDF5_DRIVER <driver> and then do gmake check in test/.
Solution:
Added a new target, check-vfd, which will take the list from
$VFD_LIST and run 'make check' with each of its members.
Platforms tested:
h5committested.
Since check-vfd is not invoked by default, I went to each machine
to invoke them by hand. The target worked fine but there were
errors reported from those driver tests. (Those errors were beyond
the scope of this make target test.)
Misc. update:
Bug fix
Description:
The $RUNPARALLEL is set even when parallel mode is not used.
Then it is used to launch some parallel natured test (e.g. example/ph5example)
which is not compiled to be so. That created some unnecessary problem
in some situation (e.g., Copper cannot "poe a.out" from an AFS space
because of the missing AFS token system bug.
Solution:
Setup RUNPARALLEL only when parallel mode is enabled.
Platforms tested:
Only tested in Copper since the change applies to IBM machines only.
(note that v1.4 will fail by default due to a problem when the default
production mode is used. But that is an error not related to this config file)
Misc. update:
Purpose: Catching up with C library
Description: Fortran Library would not configure correctly with PGI compilers
because configure couldn't find any appropriate filesin the config
directories.
Solution: Added new files for PGI compilers support on Linux 2.4
Platforms tested: arabica(C and F90), burrwhite (pgcc and pgf90), modi4 (F90 and parallel)
Misc. update:
Bug fix.
Description:
-O2 -finline-functions still causes production builds on eirene to fail.
Solution:
Downgrade optimization on gcc 2.95.x (x<3) to -O -finline-functions
Platforms tested:
Linux 2.2 (eirene)
Bug fix w/gcc 2.95.x where x<3
Description:
-O3 optimization level causes problems for gcc 2.95.2 on eirene
Solution:
Only enable -O3 if using gcc 2.95.x (where x>=3) or gcc 3
Otherwise, use older setting of -O2 -finline-functions
Platforms tested:
FreeBSD 4.7 (sleipnir)
Linux 2.2 (eirene)
bug fix, features.
Description:
removed the cache of sizeof_long since it varies between 32 and 64 bits.
Set xlc and mpcc_r as the default compiler for serial and parallel modes.
Added -D_LARGE_FILES by default to support large file size.
Added gcc gnu-flags when gcc compiler is used (not working yet.)
Platforms tested:
Tested in Copper only since that is the only AIX machine on site.
Code cleanup
Description:
Clean up miscellaneous warnings which have crept into the code.
Fix "_POSIX_C_SOURCE not defined" warning on FreeBSD.
Adjust gcc compiler flags to be more concise for production mode.
Refactor the H5O code so that there is a stronger boundary between code
in the H5O package and code in the library which just calls H5O routines.
Platforms tested:
Tested h5committest {arabica (fortran), eirene (fortran, C++)
modi4 (parallel, fortran)}
FreeBSD 4.7 (sleipnir) serial & parallel and gcc 2.95.4 & gcc 3.2.2
Misc. update:
Update MANIFEST if you add or remove any file.
