From 9bca9d684bd7d5179f30fb92afa9dee1e53f69cd Mon Sep 17 00:00:00 2001 From: Albert Cheng Date: Mon, 20 Apr 2009 21:02:46 -0500 Subject: [svn-r16814] New feature(Bug 230): Embed the content of libhdf5.settings into the hdf5 executables so that an "orphaned" executables can display (via the Unix strings command, for example) the library settings used to build the executables. This is a prototype implementation. Much improvement is needed. configure.in: Added the --disable-embedded-libinfo option to disable this feature. configure: src/H5config.h.in: Generated by autotools like automake. src/H5detect.c: Implement insert_libhdf5_settings() to insert the contents of libhdf5.settings into the library as an extern string variable so that it is included in all HDF5 executable. Much improvement is needed. fortran/src/Makefile.in: Auto-generated by bin/reconfigure. (i.e., I did make any changes to cause its direct regeneration). Tested: Jam serial, using default and --disable-embedded-libinfo, configure options. --- configure | 78 ++++++++++++++++++++++++++++++++++++------------------- configure.in | 19 ++++++++++++++ src/H5Z.c | 2 +- src/H5config.h.in | 3 +++ src/H5detect.c | 64 +++++++++++++++++++++++++++++++++++++++++++++ 5 files changed, 139 insertions(+), 27 deletions(-) diff --git a/configure b/configure index b524b3a..edac543 100755 --- a/configure +++ b/configure @@ -1646,6 +1646,8 @@ Optional Features: --enable-strict-format-checks Enable strict file format checks, default=yes if debug flag is enabled, no otherwise + --enable-embedded-libinfo + Enable embedded library information [default=yes] Optional Packages: --with-PACKAGE[=ARG] use PACKAGE [ARG=yes] @@ -8078,13 +8080,13 @@ if test "${lt_cv_nm_interface+set}" = set;
