[linux-audio-user] Success Report: FreeBob on Dynebolic (with HowTo)

Took me quite a while, but I was successful at setting up my Roland FA-101 firewire audio interface on Dynebolic! CHIMES AND MAJESTIC TRUMPETS I downloaded libfreebob from subversion. At the time of writing, libfreebob SVN requires three libraries, libraw1394 1.2.1+, libieee61883 1.1 and libavc1394 0.5.3. These are all newer than the versions shipped with dyne. The first two are in the 'video' module, presumably because of firewire being common among digital video cameras. The last is in the dyne /usr tree. In order to be able to make permanent modifications to the system, I created a dynebolic SDK. -- dynesdk makesdk cp /mnt/cdrom/* /mnt/hd1/1/dyne/SDK/cdrom -R -- Then, I set development mode for 'video' module and deleted the old versions of the libraries inside. -- dynesdk devel video rm -R /opt/video/lib/libraw1394* rm /opt/video/lib/pkgconfig/libfraw1394.pc rm -R /opt/video/include/libfraw1394* rm -R /opt/video/lib/libieee61883* rm /opt/video/lib/pkgconfig/libieee61883.pc rm -R /opt/video/include/libieee61883* dynesdk squash video -- Next, I removed the third library. No mode setting was necessary as this is part of the core system, which will be 'checked out' with a single dynesdk command when all modifications are complete. -- rm -R /usr/lib/libavc1394* rm /usr/lib/pkgconfig/libavc1394.pc rm -R /usr/libavc1394* -- Third, I installed the latest release of libraw1394. I used release versions wherever possible, and this was one of the two cases where it worked out. Downloaded 1.2.1 from http://sourceforge.net/projects/libraw1394 -- tar -xvzf libraw1394-1.2.1.tar.gz cd libraw1394-1.2.1 ./configure --prefix=/usr make make install make dev -- Next, I installed the latest SVN of libieee61883 and built it. -- svn checkout svn://svn.linux1394.org/libiec61883/trunk/ libiec61883 cd libiec61883 autoreconf -f -i -s ./configure --prefix=/usr make make install -- And the latest release of libavc1394. -- tar -xvzf libavc1394-0.5.3.tar.gz cd libavc1394-0.5.3 ./configure --prefix=/usr make make install -- Now, finally, libfreebob from subversion can be installed: -- svn co \ https://svn.sourceforge.net/svnroot/freebob/branches/libfreebob-1.0 \ libfreebob cd libfreebob autoreconf -vis ./configure --prefix=/usr make make install -- You can test by running tests/test-freebob discover in the build directory. There should be several pages of output and some information on your device printed somewhere. If it doesn't work out, please go ahead and post here! Now, the latest subversion of jack is necessary in order to properly support freebob, since there were some freebob API changes recently. Note I did not uninstall jack 100.0.0 but trusted the new jack to overwrite since it is installed in the same prefix. -- svn co http://subversion.jackaudio.org/jack/trunk/jack jack cd jack ./autogen.sh --prefix=/usr --with-default-tmpdir=/tmp make make install -- Well, that's it! Test with the following: jackd -d freebob If jack stays running you were successful! Once you have a running jack, you need the latest QJackCtl in order to bring FreeBob support to ease of use: (When prompted for a password after CVS login, simply press return) -- cvs -d:pserver:anonymous@qjackctl.cvs.sourceforge.net:/cvsroot/qjackctl\ login cvs -z3 \ -d:pserver:anonymous@qjackctl.cvs.sourceforge.net:/cvsroot/qjackctl co \ qjackctl cd qjackctl make -f Makefile.cvs ./configure --prefix=/usr make make install -- Now set up QJackCtl according to your favorite parameters: Freebob backend, and probably something along the line of 64 frames per period and 2 periods per buffer. Also set the number of input and output channels to match your sound card. If in doubt, you can run -- jackd -d freebob jack_lsp -- and count the number of channels. And now for that piece of special dyne magic that makes dyne unique in the operating system world! -- dynesdk mkusr dynesdk mkinitrd dynesdk mkiso -- ... and you have a bootable CD image with freebob working. Actually, before you do this, you might want to install some additional software, such as ZynAddSubFX. Stay tuned! I will be releasing a modified version of dyne to suit my needs as a musician, and it might just suit your needs as well. It smells of softsynths and stability, ladies and gentlemen! Thanks for taking the time to read this Carlo PS: Pieter, your help was invaluable, thank you.
