libopenblas, OpenBlas, cblas.h unavailable to link during make

[ghost]

Hi, I want to compile llama.cpp with blas in termux.

Expected Behavior

Currently, I use make LLAMA_OPENBLAS=1, and it fails to make. I expect it to locate one of the libraries for blas:

libopenblas/stable,now 0.3.23 aarch64 [installed],

or

openblas-static/termux,now 0.3.7 aarch64 [installed].

Alternatively, I also have:
$HOME/OpenBLAS-0.3.23

Current Behavior

'make LLAMA_OPENBLAS=1
I llama.cpp build info:

Steps to Reproduce

1. Use termux to move llama.cpp to $HOME
2. Cd then cd llama.cpp
3. make LLAMA_OPENBLAS =1

You can use cmake for better detection of the OpenBLAS location. If you insist on using make, just modify the Makefile to point it to the right location.

Thanks for your response. My apologies, I accidentally closed the issue while figuring out how to use github ui.

I compiled with cmake LLAMA_OPENBLAS=1 llama.cpp. It appeared to work, but it doesn't create a main file, so I dunno how to run it to test if blas is working. Please excuse my ignorance!

I edit the MAKEFILE line 104 to 'CFLAGS += -DGGML_USE_OPENBLAS /data/data/com.termux/files/usr/lib/'

Also tried 'CFLAGS += -DGGML_USE_OPENBLAS /data/data/com.termux/files/usr/lib/libopenblas_armv8p-r0.3.7.a'

And 'CFLAGS += -DGGML_USE_OPENBLAS /data/data/com.termux/files/home/OpenBLAS-0.3.23'

But I'm still receiving the same error message during make.

'clang-16: warning: /data/data/com.termux/files/home/OpenBLAS-0.3.23: 'linker' input unused [-Wunused-command-line-argument]
ggml.c:149:10: fatal error: 'cblas.h' file not found'

Thanks for any direction.

Hi,

editing the MAKEFILE line 104 to CFLAGS += -DGGML_USE_OPENBLAS -I/data/data/com.termux/files/usr/include/openblas

Allowed me to compile and now BLAS is working as expected. Thanks!
