[Osw-users] GUI freezes with ALSA, no sound with Jack.

[smoerk <sm...@gm...>]

Hello,

after a few hours of compiling (why is C++ so slow?), I tried OSW 1.2.3 
on Linux. I have 2.6.8 Kernel, TCL 8.4.7, gcc 3.3.5, Jack 0.99 and a 
Soundblaster Live. When I click on the speaker symbol, I can hear audio, 
but the GUI does not respond anymore. I can move windows (which I think 
the windows manager is responsible for), but there is no response inside 
the windows. Even the light of the speaker doesn't get red.

With Jack there is no sound and with OSS no sound and also a froozen GUI.

Any idea how to solve this problem?

OSW makes heavy use of C++ templates, which at compile time results in a
sort of combinatoral explosion as it recompiles the same piece of code
over and over for every known type, of which there are many -- at least,
I think that is what is happening, to be honest I don't entirely
understand the type/template system in OSW.

I think we have a 1.2.4 release, but I have not been testing on linux
lately (rather, macos x), so I'm not sure what the situation is.  I'll
try it out later today and report back.

1.2.4 is Mac only - 1.2.3 is still the latest release for Linux.

While I can't yet answer the core question (freezing GUI), a couple of side
issues:
1)  The Jack driver isn't yet complete, though is part of the source code.
2)  C++ compilation speed seems to be quite variable.  On my main Linux box
(my 2.4GHz, 2.4.x kernel gcc 3.4) it runs extremely fast.  But on my OS X
iBook (800MHz, running Apple's gcc 3.3 port), it runs quite slow, though not
painfully so.  The key seems to be having not only a fast processor, but
most importantly a large amount of RAM (I recommend at least 512MB), and a
fast disk system if you do need to swap.  Most of the C++ compile time is
taken in the optimization phase, which is very memory intensive and can
start thrashing if it doesn't have enough memory - you can use "top: to see
this.

Will look into the freeze issue - though i haven't been able to reproduce it
yet.  Anyone else seeing this behavior?
