Unfortunately, Libjpeg ignores DESTDIR and has no equivalent, so you're going to have to either edit the Makefile, or you have to call '''make install''' as follows:
+
{{Note|If you wish to use ''DESTDIR'' when installing libjpeg, the optional patch above must be applied.}}
  
−
make bindir=<DESTDIR>/usr/bin \
+
== Non-Multilib ==
−
mandir=<DESTDIR>/usr/man/man1 \
 
−
libdir=<DESTDIR>/usr/lib \
 
−
includedir=<DESTDIR>/usr/include install
 
  
−
Of course <DESTDIR> is whatever path that you'd normally set DESTDIR to, and if you're installing the N32 or 64Bit versions, you need to change libdir to /usr/lib32 or /usr/lib64 as appropriate.
+
Apply the optional, ''DESTDIR'', patch:
  
−
You also have to create the target directories before running '''make install''' since it won't create them for you:
+
patch -Np1 -i ../jpeg-{{Libjpeg-Version}}-destdir-1.patch
−
 
 
−
  install -dv <DESTDIR>/usr/bin
 
−
  install -dv <DESTDIR>/usr/man/man1
 
−
  install -dv <DESTDIR>/usr/lib (or lib{32} or lib{64})
 
−
  install -dv <DESTDIR>/usr/include

Introduction to Libjpeg

Libjpeg is a library developed by the Independent JPEG Group for JPEG image compression.

Note

If you wish to use DESTDIR when installing libjpeg, the optional patch above must be applied.

Non-Multilib

Apply the optional, DESTDIR, patch: 

patch -Np1 -i ../jpeg-8d-destdir-1.patch

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

Apply the optional, DESTDIR, patch: 

patch -Np1 -i ../jpeg-8d-destdir-1.patch

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

Apply the optional, DESTDIR, patch: 

patch -Np1 -i ../jpeg-8d-destdir-1.patch

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

Apply the optional, DESTDIR, patch: 

patch -Np1 -i ../jpeg-8d-destdir-1.patch

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

Contents

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.
