Install LIBPNG from Source Code

This section provides a tutorial example on how to install LIBPNG library manually from source code files on macOS.



From last tutorial, we know that Imager::File::PNG requires the PNG library. Here what I did to install it from its source code.

1. Go to LIBPNG Website at https://sourceforge.net/projects/libpng.

2. Clicks "Files > libpng16 > 1.6.37" and download "libpng-1.6.37.tar.gz".

3. Unzip and untar it to extract source files in libpng-1.6.37 folder.

4. Build binary files with these commands:

herong$ mkdir ~/lib/libpng
herong$ cd libpng-1.6.37

herong$ ./configure --prefix=/Users/herong/lib/libpng
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... ./install-sh -c -d
checking for gawk... no
checking for mawk... no
checking for nawk... no
checking for awk... awk
checking whether make sets $(MAKE)... yes
...
configure: creating ./config.status
config.status: creating Makefile
config.status: creating libpng.pc
config.status: creating libpng-config
config.status: creating config.h
config.status: executing depfiles commands
config.status: executing libtool commands

herong$ make check
rm -f pnglibconf.c pnglibconf.tf[45]
awk -f ./scripts/options.awk out=pnglibconf.tf4 version=search\
	    ./pngconf.h ./scripts/pnglibconf.dfa\
	    ./pngusr.dfa  1>&2
awk -f ./scripts/options.awk out=pnglibconf.tf5 pnglibconf.tf4 1>&2
rm pnglibconf.tf4
mv pnglibconf.tf5 pnglibconf.c
...
PASS: tests/pngimage-quick
PASS: tests/pngimage-full

herong$ make install
/Library/Developer/CommandLineTools/usr/bin/make  install-am
 ./install-sh -c -d '/Users/herong/lib/libpng/lib'
 /bin/sh ./libtool   --mode=install /usr/bin/install \
    -c   libpng16.la '/Users/herong/lib/libpng/lib'
libtool: install: /usr/bin/install -c .libs/libpng16.16.dylib \
    /Users/herong/lib/libpng/lib/libpng16.16.dylib
...
+ ln -s libpng16/pngconf.h pngconf.h
+ cd /Users/herong/lib/libpng/lib/pkgconfig
+ rm -f libpng.pc
+ ln -s libpng16.pc libpng.pc

Now we have LIBPNG library ready in the ~/lib/libpng folder.
