The Libtool package contains the GNU generic library support script. It wraps the complexity of using shared libraries in a consistent, portable interface.
The following config.cache
entry
overrides the default search path, which does not take
multilib into account:
echo "lt_cv_sys_dlsearch_path='/lib /usr/lib /usr/local/lib /opt/lib'" > config.cache
Prepare Libtool for compilation:
CC="gcc ${BUILD32}" ./configure --prefix=/usr \ --cache-file=config.cache
Compile the package:
make
To test the results, issue:
make LDEMULATION=elf32ppc check
.
The meaning of the override on make check:
LDEMULATION=elf32ppc
Libtool tends to do the wrong thing when building for multilib,
at least on the non-default size(s) of architecture. The causes of
these errors are not well understood and they can appear, or disappear,
as a result of apparently innocuous other changes in the build. In
this version of the book, one of the tests (pdemo-make) fails to link
because it tries to link the 32-bit objects against 64-bit system
libraries. This option enables the test to succeed without impacting
the other tests (compare the common alternative fixes of
LD="gcc ${BUILD32}"
which causes far fewer tests
to be executed, and configuring with
LDFLAGS='-L/lib -L/usr/lib'
which in this case
causes other tests to fail.)
Install the package:
make install
Prepare libtool
to be wrapped by
the multiarch wrapper. Libtool by itself is not multilib aware:
mv -v /usr/bin/libtool{,-32}
