Hi Stéphane,
thank you so much for your help. You pushed me into the right direction.
I did a read-up about the tiger lake optimizations and didn't want to
miss out on them. In an other article I found that gcc version 10 added
support for these optimizations, so I updated gcc and g++. Just rand
faust2cupercollider without any complaints from the compiler. (have to
test the result in supercollider first, to be sure everything worked as
expected, of course ... oh and maybe I now can compile supercollider
with native support as well)
Thanks again!
Oliver

It seems that for whatever reason, your gcc compiler ve supposedrsion does not
support the native CPI architecture (tigerlake in your case).
The faust2supercollider script uses the CXXFLAGS variable here:
https://github.com/grame-cncm/faust/blob/master-dev/tools/faust2appls/faust2supercollider#L20
And this CXXFLAGS variable is defined in the faustoptflags script here :
https://github.com/grame-cncm/faust/blob/master-dev/tools/faust2appls/faustoptflags#L22
By default -march=native is used and « native » would mean tigerlake on your
machine.
So in faust2supercollider script line 20,
- try to change for this line (so using the « generic » compilation mode instead of
«native » ) CXXFLAGS+=" $MYGCCFLAGSGENERIC" # So that additional CXXFLAGS can
be used
- re-install (« sudo make install » in Faust main folder)
- then try faust2supercollider again.

Anything else that could be of importantance?

Could it be a C++ compiler version ? Is it the Xcode installed one?

Hi guys,
I ran into a problem today. I have a new machine with an i5 11th gen
(tigerlake). Tried to compile some dsp-apps for supercollider today (with
faust2supercollider) and got the following message

well ... basically I guess it says that tigerlake's not recognized.
I had a look and found that faust2object seems to know this key already, so I
thought perhaps it's the version of faust I had and compiled it to get the
newest one. But that didn't change anything.
I also tried to find a switch to tell the compiler to use some generic settings
but didn't have any luck.
So I thought perhaps one of you got an idea, a solution or a patch that could
help me with that issue.
Any help or suggestion is highly appreciated!
Thanks,
Oliver
