Introduction to libjpeg
The libjpeg package contains libraries that allow compression of image files based on the Joint Photographic Experts Group standard. It is a "lossy" compression algorithm.
Dependencies
Non-Multilib
Compile the package:
patch -Np1 -i ../jpeg-8d-config_update-1.patch && ./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:
patch -Np1 -i ../jpeg-8d-config_update-1.patch && CC="gcc ${BUILD32}" ./configure --prefix=/usr --enable-static --enable-shared && make
Install the package
make install
N32
Compile the package:
patch -Np1 -i ../jpeg-8d-config_update-1.patch && 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:
patch -Np1 -i ../jpeg-8d-config_update-1.patch && 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.{so,a} |
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. |
