Hi,

Not sure this is the right forum, but here goes:

Since I need(want) features (namely alsa_in/out) in Jack 116 and Ubuntu Studio comes with 109 I need to build the latest.

The following is from the FAQ at www.jackaudio.org with my questions mixed in:

---------------
Prerequisites
* 2.4, 2.5 or 2.6 series kernel with tmpfs turned on (CONFIG_TMPFS)

Ok, so I have 2.4 from the Ubuntu Studio. But how do I determine if tmpfs is on?


* Shared memory file system mounted on /dev/shm. add the following to /etc/fstab to get it mounted at boot:

shmfs /dev/shm shm defaults 0 0

(Note: you may have to make the /dev/shm directory)


Ok, so /dev/shm exists, but is mounted as devshm already. Adding the above and rebooting shows no errors in any log that I found, but only devshm shows up when I "mount -l"


Once you have the correct shmfs support, you should be able to build jack with the following sequence of commands:

sh ./autogen.sh
./configure
make
make install


Obviously these get typed in a terminal session. But:

as root?
what directory should I be in?
where do I extract the tar ball that has the source?


Haven't done anything like this in a UNIX like system since the late 1980's...so the gray cells are a bit rusty.;)
