Sorry form my very bad “spaghetti-english” powered by Gøogle, by i don’t speak it.
Now, this is the question:
it’s possible to build Ardour without SSE optimizations? My CPU is an AMD Athlon Thunderbird.
How can “instruct” scons?
I tried with:
export CFLAGS="-O3 -mno-sse -mno-sse2"; export CXXFLAGS=$CFLAGS
but it seems not work.
Thanks in advance for your help
I have the same CPU (AMD Athlon Thunderbird 1,4 GHz 133 MHz fsb) and also thought about this some time ago.
Do I get any performance gain if I compile without SSE (if the CPU doesn’t support SSE like the AMd Athlon Thunderbird)?
Thanks philicorda, you’re right when you wrote:
“I think you can do it like this: scons FPU_OPTIMIZATION=0”
Now ardour is compiled with “mmx” and “3dnow” support only.
I think you can do it like this:
try scons --help for other options.
