Install Sage on 64bit Ubuntu (7.10)

[uggie]

I did get Sage to work with the regular 32bit version of Ubuntu 7.10, but I have this lovely AMD 64X2 board that I would really like to run natively. I've got an MSI K9N board with the previously mentioned 64X2 (Dual Core 4600+), a PVR500 and an Nvidia 8600.

Has anyone successfully installed Sage for Linux on a 64bit machine actually running in 64bit? I have come close, but now I get a final error during setup of:

Capture Error on Playback ERROR(620,0x16) There was a problem setting up software audio compression.

Using dmesg I find this weirdness at the tail:

[ 4456.451181] ioctl32(java:13689): Unknown cmd fd(58) cmd(40085618){t:'V';sz:8} arg(ded8dc98) on /dev/video1

For those brave enough to try, I do have tips for getting this far on an Ubuntu 7.10 system.

In Synaptic install the following:

ia32-libs
ia32-sun-java6-bin
libc6-dev
libc6-dev-i386
gcc-4.1-multilib (or whatever version is the same as the highest install gcc)
g++-4.1-multilib (or whatever version is the same as gcc)
g++ (might be able to just do this one - I haven't checked the deps)
autoconf
automake
libtool

You will have to change the default java implementation to the 32bit version:
update-alternatives --config java (select the 32bit version)

download faac, faad2, lame, mad from sourceforge.net
download libraw1394, libavc1394 from linux1394.org

Now you get to build 32bit versions of these libraries. Those more experienced in Debian or Ubuntu may know of an easier way to grab and install the 32bit versions cleanly, but this is what I did.

You will have to run the bootstraps on a few of the packages and then configure with:

./configure --libdir=/usr/local/lib/lib32 CFLAGS=-m32 CXXFLAGS=-m32

Note that you can place the output libs wherever you want. I chose /usr/local/lib/lib32 to prevent any confusion in the future. This does require you to override a PKG_CONF_PATH in one of the 1394 builds, but that's not too hard. Once all of the libs are built you need to refresh the linker cache with:

/sbin/ldconfig -n /lib/where/you/put/things

After that everything works except for the audio compression error I mentioned at the beginning. The client mplayer reads the video inputs just fine. Any thoughts?

wow that's far more complicated than MythTV, and here I was going to ask if anyone had luck running sage under Ub. 7.10 64bit with Compiz ON because MythTV won't record or playback as long as Compiz is ON. So you just revealed that Sage more issues than mythtv for me thanks.

SageTV is a 32-bit app. If you run it in a 32-bit OS, the install is not nearly as painful. In fact the latest beta offers Debian pkgs (1st time) for those using apt.
