hi list,
i read some threads in the ardour forum about optimizing the jackd
build, so i would like to find out, if i can build jackd here with more
optimizing ...since i think that more optimizing is better than less
optimizing??
the way i am building jack until now is simply:
./configure --with-default-tmpdir=/dev/shm/
add --enable-dynsimd to turn on SSE. Helps a LOT.
when i run configure like this, i turns:
jack-audio-connection-kit 0.103.0 :
| Build with ALSA support............................... : true
| Build with FreeBob support............................ : false
| Build with OSS support................................ : true
| Build with CoreAudio support.......................... : false
| Build with PortAudio support.......................... : true
| Compiler optimization flags........................... : -DREENTRANT
-O3 -fomit-frame-pointer -ffast-math -funroll-loops -march=i686 -mmmx
-msse -mfpmath=sse
| Compiler full flags................................... :
-I$(top_srcdir)/config -I$(top_srcdir) -I$(top_srcdir) -D_REENTRANT
-D_POSIX_PTHREAD_SEMANTICS -Wall -g -g -O2 -I/usr/include/nptl
| Install dir for libjack + backends.................... :
${exec_prefix}/lib/jack
|
| Default driver backend................................ : "alsa"
| Shared memory interface............................... : "System V"
| Install prefix........................................ : /usr/local
the processor type in the kernel config here is 'Pentium M' but i don't
know if the '-march=i686' could be changed with something like 'pentium M'.
since i am using a self made kernel, only a little help in this issue
would help me a lot.
cheers,
doc
