General shared library improvements for CYGWIN / AIX
Description:
Shared libraries are disabled on both CYGWIN and AIX due
to inability to build them correctly. Part of the problem
in both of these situations is the lack of the libtool
flag -no-undefined, which tells libtool that all needed
symbols are defined at link time (a requirement on these
systems) and that it's okay to build shared libraries.
Another problem are lack of dependencies between wrapper
libraries and core C HDF5 library.
This patch addresses both of these by fixing configure to
add in -no-undefined flag for libtool during linking and
adds automake dependencies in the Makefile.am files.
After testing, both CYGWIN and AIX now generate shared
libraries, but there are still some test failures in each.
(cache_api, dt_arith, and testerror.sh on CYGWIN, and
fortran tests on AIX).
Even though the shared libraries are not quite perfect,
this is a general improvement to what we had before, so
I'm applying the patch anyways. Note that default behavior
of shared libraries on these systems being disabled has
NOT been changed and requires the use of the
--enable-unsupported to attempt to build them.
We will need to address the test failures in each
architecture prior to formally supporting shared
libraries on each.
Tested:
h5committested & CYGWIN tested (on bangan)
(AIX tested by Albert on bp-login2)
Add "silent make" mode configure option.
Description:
Automake 1.11 has a new option available that allows for a
silent make mode. This functionality needs to be explicitly
enabled in configure.in via the use of the automake macro
AM_SILENT_RULES, which is what this commit is adding.
This introduces a new configure option:
--{en|dis}able-silent-rules
This option is on by default, and simplies compile and link
line outputs when building the library. Disabling this option
will print full "verbose" output (i.e., full compile and
linking lines for each target).
Tested:
This was tested on jam & h5committested
Fixed issue HDFFV-5866 (BZ 2156). Changed scripts to run examples to use specific names for compiled executable files instead of a.out, which did not work on Cywin as it produces a.exe by default. Removed issue from known problems section of RELEASE.txt.
Tested with Cygwin 1.7.8 on Windows 7.

- Revise shared Fortran library disabling scenarios in configure
- Improve configure output summary
Description:
Shared Fortran libraries are not supported on Mac, but were being
disabled by configure in a way that also forced the C libraries
to be static-only. This has been fixed, so now only shared Fortran
is disabled while shared C can remain.
This prompted two additional changes:
1. While working on the check that addresses whether or not
shared Fortran libraries are allowed, removed old and no
longer needed check(s) that disable shared Fortran
libraries with HP, Intel 8, PGI, and Absoft compilers.
(Essentially, Mac is the only situation in which Fortran
shared are disabled by configure.)
2. Having two different states of libraries (i.e. shared C
library with static-only Fortran library) was not apparent
in the configure summary, which labeled all libraries as
either shared and/or static. I've added lines to both the
C++ and Fortran output sections to list shared/static-ness
of these libraries specifically.
Additionally, I've made sure that the new --enable-unsupported
configure option correctly overrides configure if it tries to
disable a shared library.
Tested:
jam, fred, & h5committest
* Fixed error in passing an array of characters with different length
field names for h5tbmake_table.
* Fixed error in h5tget_field_info_f with packing the C strings
into a fortran array of strings.
* Added optional arguement to h5tbget_field_info_f called maxlen
which returns the maximum string character length in a field name
element.
* Uncommented out test for h5tbget_field_info_f in the test program
and added additional checks for the output.
Tested: jam (intel and gnu compilers)
Bring changes from Coverity branch to trunk:
r19930:
Fix memory leaks involving VL attributes in h5repack and h5diff. The buffers in
copy_attr and diff_attr were not checked for the presence of a vlen before being
freed, and vlen storage was never reclaimed. Added checks and calls to
H5D_vlen_reclaim().
r19933:
Purpose: Fix memory leak in H5L_move_cb()
Description: H5L_move_cb copied the source link using H5O_msg_copy() but freed
it manually using H5MM_xfree(). Since H5O_link_copy allocates the link using
H5FL_MALLOC, this causes the link to be allocated from the free list but is
never put back on the free list when it is freed. This prevents the link free
list from shutting down properly. Modified H5L_move_cb() and H5L_move_dest_cb()
to free the link properly using H5O_msg_free().
r19973:
Fix resource leaks by freeing string created by HD5f2string
r19974:
Issue #345: Inialize buf variable to null
Tested on:
Mac OS X/32 10.6.6 (amazon) w/debug & production
(h5committested on Coverity branch)
Bring Coverity revisions from branch back to trunk, and clean up some other
misc. compiler warnings also.
r19500:
Fix coverity items 1446 and 1447. Moved up calls to memset in test_cont in
ohdr.c so the test never tries to close uninitialized locations.
r19501:
Fix coverity items 1398-1445. Various uninitialized variable errors in fheap.c.
r19502:
Fixed coverity issue 579 and some additional warnings in the file as well.
r19503:
Bug fix: This fix addressed the "RESOURCE_LEAK" problems #789 and 790, run 26
r19504:
minor mods to try to keep coverity from flagging false positives.
r19505:
Fixed coverity issues 566 - 571. Declared variables that are passed to functions that use them as arrays to be arrays of size 1.
Tested on:
Mac OS X/32 10.6.4 (amazon) w/debug, production & parallel
(h5committested on trunk)
