Solve the jpeg installation error of linux64-bit: make:./libtool: Commandnotfound

First, check whether libtool and libtool-ltdl-devel are installed.

1. rpm-qa | grep libtool # wget: http://ftp.gnu.org/gnu/libtool/libtool-2.2.6a.tar.gz

#./Configure

# Make

# Make install

Then enter the source code directory of the jpeg-6b, and then perform the following steps, remember! COPY to the current directory note the following points (.)

The path of config. sub and config. guess on the internet is incorrect. It should be under/usr/share/libtool/config/, instead

/Usr/share/libtool/

# Cd jpeg

# Cp/usr/share/libtool/config. sub.

# Cp/usr/share/libtool/config. guess.

That is, the two configuration files in libtool are used to overwrite the corresponding files in the jpeg-6b directory.

Make clean and then re-configure (remember to re-configure; otherwise, this error is still prompted)

If you do not have the permission, create the corresponding folder and make install again.
