makefile.unix

# This makefile is a simpler alternative to the autoconf-based build
# system, for simple local building of the libraries and tools.
# It will not install the libraries system-wide, but just create the 'cwebp'
# and 'dwebp' tools in the examples/ directory, along with the static
# library 'src/libwebp.a'.
#
# To build the library and examples, use:
#    make -f makefile.unix
# from this top directory.

#### Customizable part ####

# These flag assume you have libpng and libjpeg installed. If not, either
# follow below install instructions or just comment out the next lines.

# To install libraries on Mac OS X:
# 1. Install MacPorts (http://www.macports.org/install.php)
# 2. Run "sudo port install jpeg"
# 3. Run "sudo port install libpng"

# To install libraries on Linux:
# 1. Run "sudo apt-get install libjpeg62-dev"
# 2. Run "sudo apt-get install libpng12-dev"

# Uncomment for build for 32bit platform
# Alternatively, you can just use the command
# 'make -f makefile.unix EXTRA_FLAGS=-m32' to that effect.
