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.
Updating autotools
Description:
Installed new autotools and used them to reconfigure HDF5.
- Automake upgraded to 1.11
- Autoconf upgraded to 2.64
- bin/reconfigure script edited to use new versions (on jam), and
run to generate new configure script and Makefile.in's.
- configure.in script edited to add "_cv_" to all AC_CACHE_VAL strings
(in order to comply with new autoconf standard).
Tested:
Tested on machines jam, smirom, liberty, linew.
Tested w/ features c++, fortran, parallel.
Tested w/ compilers gcc, pgcc, icc.
Further testing via Daily Tests should catch any other outliers. Upon
passing DT's, I'll propogate the new tools into 1.8, hdf4, et cetera.
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.
- Updated bin/reconfigure to use latest version of automake (1.10.2).
Re-generated Makefile.in's by running bin/reconfigure.
- Added libtool version numbers to c++, fortran, hl, hl c++, and hl fortran
libraries.
Tested:
jam, liberty, smirom
Bug Fix
Description:
Fixing BZ #1381. The --includedir=DIR configure option, which is used
to specify the installation location of C header files, did not work
correctly as the path was hard-coded in config/commence.am. I'm presuming
this is because an older version of automake didn't know where to put
c header files. In any case, removing this line now defaults the includedir
to the same directory that it is currently hard-coded to, and also fixes
the configure flag to allow customization of this value.
Tested:
jam, liberty
the way h5ls prints types, it starts searching for NATIVE types first. One solution would be h5ls not to detect these native types, using for example the same print datatype function that h5dump does, that would make the output look the same on all platforms ("32-bit little-endian integer" would be printed instead). Drawback, this "native" information would not be available. Other solution is to have not one but 2 expected outputs and make the shell script detect the endianess and compare with one output or other
tested: h5committest
Description:
- Remove need to set LD_LIBRARY_PATH when using shared szip library.
- Libtool 2.2.6a is now used to generate libraries.
- 'make check install' dependency bug is fixed, and should no longer
break the build.
- removed hard coding of shell in config/commence.am, as this causes
problems on Solaris with the new version of libtool.
- RELEASE.txt with appropriate changes.
Tested:
- kagiso, smirom, linew (merged from 1.8, pretty quick tests)
Description:
The fortran Makefile.am used HDF_FORTRAN to indicate it is part of the
Fortran API source so that conclude.am will give fortran api prefix in the
test output. The symbox HDF_FORTRAN is also used in configure for a different
purpose (indicated --enable-fortran). They conflicted.
Similar problem for the symbol HDF_CXX.
Solution:
Changed all the involved Makefile.am to use "FORTRAN_API" instead. It is
a more appropriate name. Same for CXX_API.
Along the way, discovered that the Makefile.am of hl/fortran/test and
hl/cxx/test did not have those symbols at all. Added them in.
Platform tested:
Kagiso only. It is a trivia change.
Improvement.
Description:
src/libhdf5.settings was the initial configure summary and is installed.
Then configure is changed to dump a summary of the configure settings to
the output and also append it to src/libhdf5.settings. That created
two different output formats and duplicated information. This is the
initial attempt to clean up this confusion and unify the output format.
It is decided to use the src/libhdf5.settings template as the unified means.
This requires more macros symbols be defined. The following symbols are
all related to generating the src/libhdf5.settings file.
AC_SUBST(EXTERNAL_FILTERS)
AC_SUBST(MPE) MPE=no
AC_SUBST(STATIC_EXEC) STATIC_EXEC=no
AC_SUBST(HDF_FORTRAN) HDF_FORTRAN=no
AC_SUBST(FC) HDF_FORTRAN=no
AC_SUBST(HDF_CXX) HDF_CXX=no
AC_SUBST(CXX) HDF_CXX=no
AC_SUBST(HDF5_HL) HDF5_HL=yes
AC_SUBST(GPFS) GPFS=no
AC_SUBST(LINUX_LFS) LINUX_LFS=no
AC_SUBST(INSTRUMENT) INSTRUMENT=no
AC_SUBST(CODESTACK) CODESTACK=no
AC_SUBST(HAVE_DMALLOC) HAVE_DMALLOC=no
AC_SUBST(DIRECT_VFD) DIRECT_VFD=no
AC_SUBST(THREADSAFE) THREADSAFE=no
AC_SUBST(STATIC_SHARED)
AC_SUBST(enable_shared)
AC_SUBST(enable_static)
AC_SUBST(UNAME_INFO) UNAME_INFO=`uname -a`
The src/libhdf5.settings.in has CONDITIONAL's added to it too. The
untrue conditions turned into a "#" and these lines are cleaned by the
post processing script.
Platform tested:
h5committest on kagiso, smirom and linew.
Description: Applying update to autotools that was applied to 1.8 a couple
of weeks ago to the trunk.
Updated bin/reconfigure script to reflect the new versions of
libtool and automake in the /home1/packages/ directory.
Rearranged configure.in script. When using libtool 2.2.2, the
libtool script doesn't generate until later in the configuration
process, so I had to move a test that parsed through the libtool
script to a point after where it was actually being generated.
Ran libtoolize on the project, and ran bin/reconfigure to
regenerate configure and Makefile.in's throughout.
Tested: kagiso, smirom, linew (h5committest)
Add work-around to allow reading files that were produced with a buggy
earlier version of the library, which could create objects with the wrong
object header message count. There is now a configure flag
"--enable-strict-format-checks" which triggers a failure on reading a file
with this sort of corruption (when enabled) and allows the object to be read
(when disabled). The default value for the "strict-format-checks" flag is
yes when the "debug" flag is enabled and no when the "debug" flag is disabled.
Note that if strict format checks are disabled (allowing objects with
this particular kind of corruption to be read) and the file is opened with
write access, the library will re-write the object header for the corrupt
object with the correct # of object header messages.
This closes bugzilla bug #1010.
