build on CPU only without GPU?

[silvacarl2]

i have tried to build on a CPU only without GPU, but i get a core dump when i run it:

./main -m models/ggml-base.en.bin -f samples/jfk.wav
whisper_model_load: loading model from 'models/ggml-base.en.bin'
whisper_model_load: n_vocab = 51864
whisper_model_load: n_audio_ctx = 1500
whisper_model_load: n_audio_state = 512
whisper_model_load: n_audio_head = 8
whisper_model_load: n_audio_layer = 6
whisper_model_load: n_text_ctx = 448
whisper_model_load: n_text_state = 512
whisper_model_load: n_text_head = 8
whisper_model_load: n_text_layer = 6
whisper_model_load: n_mels = 80
whisper_model_load: f16 = 1
whisper_model_load: type = 2
whisper_model_load: adding 1607 extra tokens
whisper_model_load: mem_required = 506.00 MB
whisper_model_load: ggml ctx size = 140.60 MB
Illegal instruction (core dumped)

just to test it, it is being built on a Hewlett-Packard HP Compaq Pro 6300 SFF, 32.0 GiB RAM, Intel® Core™ i7-3770 CPU @ 3.40GHz × 8, Ubuntu 22.04.1 LTS

any ideas what we should try?

Please provide output of the following:

make clean
make

that nailed it. needed to do make clean, then make. will save for each CPU we are testing with.
