Hello

I'd like to ask a few questions about Ardour and Linuxsampler.

I have compiled them both, and notice something.
Linuxsampler gives me "Detected features: disabled at compile time" when I started in in commandline.
It should have given me "Detected features: MMX SSE SSE2". I think it is caused by the configure script
failing to detect my cpu because there is "#define ARCH_X86 0" in my config.h.
So I fixed it by adding ARCH_X86 1 in it and recompiled.

In ardour I cannot choose the denormal handling options because they are greyed out.
And starting ardour2 from the commandline gives me

ardour: [INFO]: Ardour will be limited to 1024 open files
loading system configuration file /usr/local/etc/ardour2/ardour_system.rc
loading user configuration file /home/shani/.ardour2/ardour.rc
ardour: [INFO]: No H/W specific optimizations in use
Warning: Unable to create "trees" RDF storage.
Performance can be improved by upgrading librdf.

I figure that ardour too did not detect my cpu correctly at compile time.
But I'm not sure what to do here.

My question is, is it the fault of my system not giving the appropriate info so that the configure script
could not detect the cpu?

For Linuxsampler, is there an appropriate way to fix it instead of editing the config.h manually.
Perhaps I should have used --build=something when running ./configure?

Ardour, I run scons with DIST_TARGET = 'x86_64' though, so why did it not able to detect my cpu?

Oh, I've seen "Warning: Unable to create "trees" RDF storage"  message a lot, is there something wrong?

Thank you
