Introduction to GNU Libtool

GNU libtool is a generic library support script. Libtool hides the complexity of using shared libraries behind a consistent, portable interface.

To use libtool, add the new generic library building commands to your Makefile, Makefile.in, or Makefile.am. See the documentation for details.

The latest stable version is 2.6.6A

Solve:Install the latest stable version

#wget:http://ftp.gnu.org/gnu/libtool/libtool-2.2.6a.tar.gz
#./configure
#make
#make install

and install jpeg again,but the Error still there.

#cd jpeg
#cp /usr/share/libtool/config.sub .
#cp /usr/share/libtool/config.guess .

[root@localhost libtool]# ls -ll

Uninstall libtool-1.5.22-6.1

[root@localhost libtool-2.2.6]# rpm -e libtool-1.5.22-6.1
[root@localhost libtool-2.2.6]# rpm -qa|grep libtool
[root@localhost libtool-2.2.6]#

Install libtool again ，then install jpeg Succeed

#cd libtool
#./configure –prefix=/usr/local/libtool
#make
#make install
#cp /usr/local/libtool/share/libtool/config/config.sub Content jpeg source
#cp /usr/local/libtool/share/libtool/config/config.guess Content jpeg source

2.Experimental

.step1

#rm -r config.guess config.sub form jpeg source content
#cp /usr/local/libtool/share/libtool/config/config.sub /usr/share/libtool/config.sub
#cp /usr/local/libtool/share/libtool/config/config.guess /usr/share/libtool/config.guess
then install jpeg
