Introduction to libjpeg-turbo

libjpeg-turbo is a fork of the original IJG libjpeg which uses SIMD to accelerate baseline JPEG compression and decompression. libjpeg is a library that implements JPEG image encoding, decoding and transcoding.

This package is known to build and work properly using an LFS-7.7 platform.

User Notes:

Installation of libjpeg-turbo

Install libjpeg-turbo by running the following commands:

sed -i -e '/^docdir/     s:$:/libjpeg-turbo-1.4.0:' \
       -e '/^exampledir/ s:$:/libjpeg-turbo-1.4.0:' &&

./configure --prefix=/usr           \
            --mandir=/usr/share/man \
            --with-jpeg8            \
            --disable-static &&

To test the results, issue: make test.



If installing libjpeg-turbo over an older jpeg installation, not all library symbolic links are updated properly. To fix this before installation, run the following as the root user:

rm -f /usr/lib/*

Now, as the root user:

make install
