Compiling on Mac Pro 5.1 - Illegal instruction: 4

[fedeblock]

It seems there's an error from sysctl which is on the right path: /usr/sbin/sysctl.
Make warns about fall back on libraries.
I'm not very savvy compiling on mac, clearly.

This is my target platform, make output and error running the example. Any help will be very much appreciated.

High Sierra 10.3.6
2 x Intel(R) Xeon(R) CPU X5675 @ 3.07GHz
NVIDIA GeForce GTX 980

[ggerganov]

If you remove the following line from the Makefile and run make clean + make does it work:

https://github.com/ggerganov/whisper.cpp/blob/4aa3bcf8a4d18fefab7f72eba0cdad1889dba08a/Makefile#L67

[fedeblock]

Always update before reporting a problem.

Lesson learned, move forward if you have the same error.

removed (line 88 for me) nevertheless, i tried with line 67 removing: CFLAGS += -mavx

		ifneq (,$(findstring f16c,$(F16C_M)))
			CFLAGS += -mf16c
		endif

did

make clean 
rm -f *.o main stream command talk bench libwhisper.a libwhisper.so

Same error, this is the output:

Did a repo pull, changed line 67 and everything worked flawlessly.

This are the benchmark results for jfk.wav if you may be interested:

I also ran into the same issue and the makefile line 67 fix worked for me as well.

I am noticing that this build of the executable runs considerably slower than my other builds. What exactly does removing line 67 do to the file processing or processor utilization?

[fedeblock]

Happened the same to me.
My old MacPro is performing a lot better in ubuntu with Pytorch cuda.

[sanchitram1]

I'm having the same error. I am trying to package whisper for a package manager tea, and one of the GitHub actions on the repo is to check whether the build works on an intel mac.

Once I fetch the latest release from GitHub, I am applying a patch where I remove line 67, but I still run into this error.

Specs are darwin+x86-64 macos-11.

Any thoughts? Happy to provide more details!
