{{Package-Introduction|JACK is a low-latency audio server, written for POSIX conformant operating systems such as GNU/Linux and Apple's OS X. It can connect a number of different applications to an audio device, as well as allowing them to share audio between themselves.|http://jackaudio.org/}}

== Dependencies ==

=== Required ===
* [[ALSA Library]]

NOTE: If you are using reiserfs or ext3fs or anything except ext2fs
for the directory where JACK puts its temporary files (/tmp by
default), then the JACK team recommends that you do *one* of the
following:
Mount a tmpfs on /tmp. You should have a lot of swap space available
in case some programs try to write very large files there.
In your /etc/fstab add a line:

none /tmp tmpfs defaults 0 0

You'll probably want to reboot here, or kill X then 'mount /tmp'.

OR

Alternatively, you can do this without affecting your /tmp:

# mkdir /mnt/ramfs

[edit /etc/fstab and add the following line]
none /mnt/ramfs tmpfs defaults 0 0

Then add --with-default-tmpdir=/mnt/ramfs to the JACK configure
line when you build it. No clients need to be recompiled.

Failure to do one of these could lead to extremely poor performance from JACK,
since its normal operation will cause bursts of disk I/O that are
completely unnecessary. This suggestion can also be used by ext2fs
users if they wish.

== Non-Multilib ==

{{Note|On 64-bit systems, JACK's default library path is ${prefix}/lib64. The <nowiki>--libdir=/usr/lib</nowiki> is to ensure the libraries always go to the proper place.}}

Compile the package:

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

Install the package

make install

== Multilib ==

=== 32Bit ===

Compile the package:

CC="gcc ${BUILD32}" PKG_CONFIG_PATH="${PKG_CONFIG_PATH32}" \
./configure --prefix=/usr --build=${CLFS_TARGET32} &&
make

Install the package

make install

=== N32 ===

Compile the package:

sed -i "/libnn=/s/lib64/lib32/" configure &&
CC="gcc ${BUILDN32}" PKG_CONFIG_PATH="${PKG_CONFIG_PATHN32}" \
./configure --prefix=/usr --libdir=/usr/lib32 &&
make

Install the package

make install

=== 64Bit ===

Compile the package:

CC="gcc ${BUILD64}" PKG_CONFIG_PATH="${PKG_CONFIG_PATH64}" \
./configure --prefix=/usr --libdir=/usr/lib64 &&
make

Install the package

make install
