Apple Lossless Audio Codec with autotools, Debian toolchain, and Visual Studio project files

ALAC

Apple Lossless Audio Codec with autotools. This repo uses the source code from http://alac.macosforge.org/ and wrap it around using autotools and Debian build toolchain.

This thing is unmaintained. Use this on your own risk.

Prerequisites, if you want to build it yourself

• git: to clone this repo. Optional if you are using a tarball.
• gcc: to compile stuff.
• g++: to compile stuff.
• autotools: to generate the build files.

How to build

Classic GNU

autoreconf -i -f
./configure
# Or if you want to
# ./configure --enable-example
make
sudo make install

Debian packaging

This method works if:

• You are using a system using dpkg (like Debian, Ubuntu, etc.)
• And you want .deb's.

I strongly suggest you to know how the Debian packaging works before using this method.

1. You need to have a packaging environment.

• If you are a maintainer or you know how to package a deb or you have a PPA, skip to step 3.
• If you don't know anything about Debian packaging, go to step 2.

2. Set up packaging environment.

• Look here for Debian users and here for Ubuntu users.

3. Edit debian/changelog.

• Change my name to your name, and my email to your email.
• Change raring to whatever your distro codename is.

4. Do:

   dpkg-buildpackage
   

5. The .deb's will be in the parent folder of the source code directory.

Visual Studio

** The resulting binary might not work. I don't know why. Do this on your own risk.**

1. Go to compat.
2. Go to corresponding folder match your VS version.
3. Open up the solution and build it.

What's included

• libalac, a library for ALAC en-/decoding.
• alacconvert, an example program using libalac to convert wav (in wav or caf container) to alac (in caf container) or vice versa. It will only build if you pass --enable-example to configure.

Documentation

alacconvert

Look at the man page.

The library

Either look at the .txt's in the repo or go to Apple's website.

Bugs Report

If you found some difficulty building it, open a new issue. Otherwise, don't bother me. Note that I am not a programmer. So if you have any patch regarding the sources I'm sorry I can't apply it. But if it is about the building system, feel free to open a new pull request or an issue.

Versioning scheme

(upstream_major).(upstream_minor)r(upstream_revision)+tg(my_release_number)

The upstream major and minor are both 0 because Apple never made a release. The upstream revision is 4 because the SVN revision I pulled out from is 4. My release number is of course my release number. "tg" is my initials.

Authors

• debian/*, Makefile.am, */Makefile.am, alac.pc.in, alacconvert.1, configure.ac, README.md: Tiancheng "Timothy" Gu

• The rest: Apple Inc.

To-do

• PPA
• EXTRA_DIST variable in Makefile.am's
