So, there is no "do not optimize away apperent volatile variables"? Volatile variables in shmclient are easily recognized -- at least I recognized them. It is the array variable which content is only read but never written. No such optimization flag? Can't believe that compilers are that dump. Juhana

Paul speaks with the voice of wisdom here, people, listen to him. Sfront is 100K+ lines of code in large part because it is trying to participate in two compiler-friendships: the SAOL programmer, and the C compiler ... ------------------------------------------------------------------------- John Lazzaro -- Research Specialist -- CS Division -- EECS -- UC Berkeley lazzaro [at] cs [dot] berkeley [dot] edu www.cs.berkeley.edu/~lazzaro -------------------------------------------------------------------------

[linux-audio-dev] kernel 2.6

by Tim Hockin

All, I haven't used kernel 2.5/2.6 for any audio stuff yet. I'm at the Linux Symposium this week - do we have any requests or gripes with 2.6 that I can relay to the core kernel guys? Audio is a workload they don't really test. Tim

[linux-audio-dev] some interesting docs for 2.6 testers...

by Joern Nettingsmeier

hello everyone! if you are thinking about testing the new 2.6-pre kernels (which would be helpful to shake out problems with typical audio-workloads that might not get tested by others), here are two links worth a read (found on lwn.net): * the 2.5 "what to expect" document by dave jones: http://lwn.net/Articles/39901/ * the wonderful world of linux 2.6 by joe pranevich http://www.kniggit.net/wwol26.html best, jörn -- All Members shall refrain in their international relations from the threat or use of force against the territorial integrity or political independence of any state, or in any other manner inconsistent with the Purposes of the United Nations. -- Charter of the United Nations, Article 2.4 Jörn Nettingsmeier Kurfürstenstr 49, 45138 Essen, Germany http://spunk.dnsalias.org (my server) http://www.linuxdj.com/audio/lad/ (Linux Audio Developers)

[linux-audio-dev] Poll: Distro for audio and MIDI development

by Ismael Valladolid Torres

Hi, I am somewhat new to Linux low-level development. I have developed for other UNIX systems before, and also for Windows NT and for JavaCard compatible smartcards. I have used (and enjoyed) Debian for a long time as a Linux user and for web development. Getting into low-level development, I find Debian sid slightly more unstable than I would find myself entirely comfortable programming with. I have tried Mandrake for Intel and PowerPC platforms and also enjoyed it as an user. Unluckily, latest Mandrake is not very well supported for PowerPC platforms, and my computer at home is an Apple G3 (even now, I know Mandrake 9.1 will be the last PowerPC version). There is no Red Hat for us (though I know about but not tried Yellow Dog). I dream about a development setup as stable but also as updated as posible. I'd like to know about your development setup, being whatever the platform (Intel, PowerPC, etc.), distros you like for development, whether if you use packaged drivers and libraries or latest versions compiled from snapshots or even CVS, also about packaged, stable or development, unstable kernels, etc. Any feedback will be very useful. Thanks in advance. Regards, Ismael
