An SCTK build error on MacBook m1 silicon

[megazone87]

The error is:

And the info in config.log shows:
clang: error: the clang compiler does not support '-march=native'

---

The -march=native seems to be introduced with PR #4336.

This is from the page of GNU about gcc on arm (m1 silicon):

-march=native causes the compiler to auto-detect the architecture of the build computer. At present, this feature is only supported on GNU/Linux, and not all architectures are recognized. If the auto-detect is unsuccessful the option has no effect.

https://gcc.gnu.org/onlinedocs/gcc/ARM-Options.html

Thus, my question is, could -march=native be good to be removed from the build of SCTK?

pls help, thx. @kkm000

@songmeixu Hi,I'm trying to build kaldi with my new M1 macbook. Just want to ask can you build kaldi successfully with M1 macbook ? What you used for the matrix library instead of MKL in m1 chip macbook?

Just want to ask can you build kaldi successfully with M1 MacBook ?

Y, after I removed -march=native in tools/Makefile.

What you used for the matrix library instead of MKL in m1 chip MacBook?

I compiled it as ./configure --shared. And by default, it goes to the new Apple M1 accelerate framework. The output-lib dependencies are like this,

@songmeixu What's the impact of removing this flag, does it make any difference?

AFAIK, the native should be handled by clang (ref: https://stackoverflow.com/questions/65966969/why-does-march-native-not-work-on-apple-m1), but not. However, a manual replacement -mcpu=apple-a14 was suggested there. I don't test the difference, as it's not a sensitive thing to me.

What about Now? Apple had removed python2 from their systems and I find I can't compile kaldi on my Macbook Air now.

Sctk shouldn't need any python?

Mine just stopped without any special ERRORs after printing a lot lines of "checking" and "config.status".
run.log

OK, but this is not errors from SCTK. Those are from dependencies check before even starting to build sctk. Can you open a new issue with "Kaldi scripts still need py2.7" title or something? Thanks

Thanks for confirmation. I just thought those errors above should be fine, that's why I used a description like "without". So this is a problem concerning to the scripts themselves(running through python2?)? I still remember there used to be an option to use python3 as the default python when making, had that been deprecated?

[jtrmal]

you could just change your tools/extras/check_dependencies.sh to ``` 1 #!/usr/bin/env bash 2 exit ``` (add exit on the second line) You will see if that helps or not -- if not, post the errors, please y.

My new fav check_dependencies hack is

echo '#!/bin/true' >tools/extras/check_dependencies.sh

This is even POSIX-compliant! :)
