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/libjpeg.so* Now, as the root user: make install Contents Installed Programs Installed Libraries Installed Directories cjpeg, djpeg, jpegtran, rdjpgcom, tjbench, and wrjpgcom libjpeg.so and libturbojpeg.so /usr/share/doc/libjpeg-turbo-&libjpeg-turbo-version; Short Descriptions cjpeg compresses image files to produce a JPEG/JFIF file on the standard output. Currently supported input file formats are: PPM (PBMPLUS color format), PGM (PBMPLUS gray-scale format), BMP, and Targa. cjpeg djpeg decompresses image files from JPEG/JFIF format to either PPM (PBMPLUS color format), PGM (PBMPLUS gray-scale format), BMP, or Targa format. djpeg jpegtran is used for lossless transformation of JPEG files. jpegtran rdjpgcom displays text comments from within a JPEG file. rdjpgcom tjbench is used to benchmark the performance of libjpeg-turbo. tjbench wrjpgcom inserts text comments into a JPEG file. wrjpgcom libjpeg.so contains functions used for reading and writing JPEG images. libjpeg.so
