8.36. Libtool-2.4.6

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

Approximate build time: 1.5 SBU
Required disk space: 43 MB

8.36.1. Installation of Libtool

Prepare Libtool for compilation:

./configure --prefix=/usr

Compile the package:

make

To test the results, issue:

make check
[Note]

Note

The test time for libtool can be reduced significantly on a system with multiple cores. To do this, append TESTSUITEFLAGS=-j<N> to the line above. For instance, using -j4 can reduce the test time by over 60 percent.

Five tests are known to fail in the LFS build environment due to a circular dependency, but all tests pass if rechecked after automake is installed.

Install the package:

make install

Remove a useless static library:

rm -fv /usr/lib/libltdl.a

8.36.2. Installation of Libtool - 32bit

Clean previous build:

make distclean

Prepare Libtool for compilation:

CC="gcc -m32" ./configure \
    --host=i686-pc-linux-gnu \
    --prefix=/usr            \
    --libdir=/usr/lib32

Compile the package:

make

Install the package:

make DESTDIR=$PWD/DESTDIR install
cp -Rv DESTDIR/usr/lib32/* /usr/lib32
rm -rf DESTDIR

8.36.3. Installation of Libtool - x32bit

Clean previous build:

make distclean

Prepare Libtool for compilation:

CC="gcc -mx32" ./configure \
    --host=x86_64-pc-linux-gnux32 \
    --prefix=/usr                 \
    --libdir=/usr/libx32

Compile the package:

make

Install the package:

make DESTDIR=$PWD/DESTDIR install
cp -Rv DESTDIR/usr/libx32/* /usr/libx32
rm -rf DESTDIR
