Introduction to Libjpeg
Libjpeg is a library developed by the Independent JPEG Group for JPEG image compression.
Project Homepage: http://www.ijg.org/
Dependencies
Non-Multilib
Compile the package:
./configure --prefix=/usr --enable-static --enable-shared && make
Install the package
make install
Command Explanations
--enable-static --enable-shared: These switches tell libjpeg to build both shared and static libraries.
Multilib
32Bit
Compile the package:
CC="gcc ${BUILD32}" ./configure --prefix=/usr --enable-static --enable-shared &&
make
Install the package
make install
N32
Compile the package:
CC="gcc ${BUILDN32}" ./configure --prefix=/usr --libdir=/usr/lib32 \
--enable-static --enable-shared &&
make libdir=/usr/lib32
Install the package
make libdir=/usr/lib32 install
64Bit
Compile the package:
CC="gcc ${BUILD64}" ./configure --prefix=/usr --libdir=/usr/lib64 \
--enable-static --enable-shared &&
make libdir=/usr/lib64
Install the package
make libdir=/usr/lib64 install

| Installed Programs: | cjpeg, djpeg, jpegtran, rdjpgcom, and wrjpgcom |
|---|---|
| Installed Libraries: | libjpeg.{a,la,so} |
| Installed Directories: | None |
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. |
|---|---|
| djpeg | decompresses image files from JPEG/JFIF format to either PPM (PBMPLUS color format), PGM (PBMPLUS gray-scale format), BMP, or Targa format. |
| jpegtran | is used for lossless transformation of JPEG files. |
| rdjpgcom | displays text comments from within a JPEG file. |
| wrjpgcom | inserts text comments into a JPEG file. |
| libjpeg.{so,a} | library is used by many programs for reading and writing JPEG format files. |
