Hi,
I'm running on Zenwalk 2.8
kernel 2.6.17-rt8
sound card Echo Layla24, P4 2.8HT, 2GB DDR.
I've installed successful all of jack, ardour and many others audio apps.

Now for linuxsampler 0.3.3 :

I've try with :
gcc 4.1.1 and 3.4.6
liblscp 0.3.1 and 0.3.2
libgig 3.0.0 and 2.0.2

In all cases, all is installed successful (exept when I build linuxsampler with
gcc 4.1.1, but now I understand...)
I've export all that must be exported... always run ldconfig...

But when I run linuxsampler, always the same error occured (in user, and I tried
in root too) :
With jackd running or not, it's all the same.
Note: I've installed LS with --enable-max-voices=256 --enable-max-streams=300
(because I use many larges giga orchestra files...) 
and --prefix=/usr/local/linuxsampler (I made a link of the bin in /usr/bin/)
