10.24. Libtool-1.5.22 32 Bit Libraries

The Libtool package contains the GNU generic library support script. It wraps the complexity of using shared libraries in a consistent, portable interface.

10.24.1. Installation of Libtool

Prepare Libtool for compilation:

CC="gcc ${BUILD32}" ./configure --prefix=/usr

Compile the package:

make

To test the results, first identify whether you are on a big- or little-endian machine. SGI machines are usually big-endian, Cobalt are usually little-endian. If in doubt you can echo ${MACHTYPE} | grep 'el-' - this will match a little-endian machine.

To test on a little-endian machine issue: make LDEMULATION=elf32ltsmip check.

To test on a big-endian machine issue: make LDEMULATION=elf32btsmip check.

The meaning of the override on make check:

LDEMULATION=[emulation]

Libtool tends to do the wrong thing when building for multilib, at least on the non-default size(s) of architecture. These 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
