Introduction to Libpng
libpng is a PNG reference library.
Project Homepage: http://www.libpng.org/pub/png/libpng.html
Dependencies
Non-Multilib
Compile the package:
Add animated PNG (apng) support (required for Mozilla-Firefox 3)
patch -Np0 -i ../libpng-1.6.12-apng-1.patch
./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

| 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. |
