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}
