Introduction to Libpng

libpng is a PNG reference library.

Project Homepage: http://www.libpng.org/pub/png/libpng.html

Non-Multilib

Compile the package: 

./configure --prefix=/usr &&
make

Install the package 

make install &&
install -v -m755 -d /usr/share/doc/libpng-1.6.12 &&
install -v -m644 README libpng-1.6.12.txt /usr/share/doc/libpng-1.6.12

Multilib

Note

Where a symlink points to a program or script which is now to be linked to the multiarch_wrapper, the symlinks must not loop. In the case of libpng we point libpng-config-32 to libpng12-config-32 instead of to libpng-config because that would loop to the multiarch_wrapper.

32Bit

Compile the package: 

CC="gcc ${BUILD32}" ./configure --prefix=/usr &&
make

Install the package 

make install &&
mv -v /usr/bin/libpng12-config{,-32} &&
ln -sfv libpng12-config-32 /usr/bin/libpng-config-32
ln -sfv multiarch_wrapper /usr/bin/libpng12-config &&
ln -sfv multiarch_wrapper /usr/bin/libpng-config

N32

Compile the package: 

CC="gcc ${BUILDN32}" ./configure --prefix=/usr --libdir=/usr/lib32 &&
make

Install the package 

make install &&
mv -v /usr/bin/libpng12-config{,-n32} &&
ln -sfv libpng12-config-n32 /usr/bin/libpng-config-n32
ln -sfv multiarch_wrapper /usr/bin/libpng12-config &&
ln -sfv multiarch_wrapper /usr/bin/libpng-config

64Bit

Compile the package: 

CC="gcc ${BUILD64}" ./configure --prefix=/usr --libdir=/usr/lib64 &&
make

Install the package 

make install &&
mv -v /usr/bin/libpng12-config{,-64} &&
ln -sfv libpng12-config-64 /usr/bin/libpng-config-64 &&
ln -sfv multiarch_wrapper /usr/bin/libpng-config &&
ln -sfv multiarch_wrapper /usr/bin/libpng12-config &&
install -v -m755 -d /usr/share/doc/libpng-1.6.12 &&
install -v -m644 README libpng-1.6.12.txt /usr/share/doc/libpng-1.6.12

Contents

Installed Programs: libpng-config and libpng12-config
Installed Libraries: libpng.so and libpng12.{so,a}
Installed Directories: /usr/include/libpng12 and /usr/share/doc/libpng-1.6.12

Short Descriptions

libpng-config is a symlink to libpng12-config.
libpng12-config provides configuration information for libpng.
libpng.so and libpng12.{so,a} are a collection of routines used to create and manipulate PNG format graphics files. The PNG format was designed as a replacement for GIF and, to a lesser extent, TIFF, with many improvements and extensions and lack of patent problems.
