If you can use cmake, try the following, may print more diagnose info.

mkdir -p build
rm -rf build/*
cd build
cmake .. -DLLAMA_SANITIZE_ADDRESS=ON && cmake --build . --config Debug
cd ..
./build/bin/main ...

what' the next?

"the next" is building llama.cpp, then moving the GGML to the correct folder. Do not load a GGML from the downloads folder.

Here are some steps to follow:

1. Clone the repo:

$HOME

git clone https://github.com/ggerganov/llama.cpp

2. Move your model to the proper directory, for example:

cd storage/downloads
mv 7b-ggml-q4_0.bin ~/llama.cpp/models

3. e. Build llama.cpp:

cd llama.cpp

make

Here's an example of using llama.cpp:

./main -m ~/llama.cpp/models/3b-ggml-q8_0.bin --color -c 2048 --keep -1 -t 3 -b 10 -i -ins

*modify -t # parameter to the # of physical cores in your device.

If you have an issue, then let me know precisely what step you made it to, and the error.

Thanks for your response. Please let us know -uname -a and lscpu.

I have to ask just in case: You're using Termux from Fdroid, yah?

Edit:

Output shows that you copied the GGML to models, which the wrong directory. The correct path is ~/llama.cpp/models.

@JackJollimore yes,termux

Sorry, I'm not certain based on your response.

Termux from the Google Playstore is incompatible.

Termux from FDroid is required.

[mqy]

@mqy @JackJollimore here's the output ,thanks!

I did not sawsee Illegal in the pasted content though. Instead, the program works fine --
the./bin/main random output some codes, right?

[adaaaaaa]

@mqy

random output some codes

yes,i run it the second time ,it output different codes now,why?

[adaaaaaa]

Termux from FDroid is required.

it's download from droid-ify...not google.

[ghost]

@mqy @JackJollimore here's the output ,thanks!

According to the output, llama.cpp works as expected from build/bin. There's no illegal instruction.

Edit: please ensure Output is readable going forward.

lscpu: failed to determine number of CPUs: /sys/devices/system/cpu/possible: No such file or directory`

is Termux is fully setup?

termux-setup-storage

termux-change-repo

apt update && apt upgrade

[mqy]

Since main from cmake works, I'm guessing the Illegal instruction is caused by an outdated main binary.

Here is the stand output pattern:

llama_model_load_internal: ggml ctx size =    0.06 MB
llama_model_load_internal: mem required  = 2862.72 MB (+  682.00 MB per state)

@adaaaaaa 's main crashed right after the first line.

@adaaaaaa would you please build mian with make again and run it?

BTW, you'd better tell us the latest commit (git log -1), it's good to follow standard bug report process, isn't?

build again and get the same result

Thanks

[ShadowPower]

I'm having the same problem with the Snapdragon 7+ Gen 2, so maybe it's a processor-specific issue.

[tcristo]

I have the same processor and same issue. Appears to be related to telling the compiler to optimize to the native processor. I use the following to work around it:

Find the directory the CMakelists.txt file is in, cd to that directory, and run the following line:

sed -i 's/add_compile_options(-mcpu=native)//g' CMakeLists.txt

Then make a build subdirectory, cd into it, and run cmake as follows:

cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_C_FLAGS='-mcpu=cortex-a35 -march=armv8.4a+dotprod' -S ../

Now run make.

You should now have a valid executable that will run without the illegal instruction problem.

[mqy]

sed -i 's/add_compile_options(-mcpu=native)//g' CMakeLists.txt

strange that:

1. LLAMA_NATIVE is OFF by default, add_compile_options(-march=native) should not be executed.
2. @adaaaaaa 's case: the main built with cmake works. make CFLAGS contains -mcpu=native but no -mfpu, that means $(UNAME_M) matches aarch64, but does not match armvX.

Related issue (previous fix) #1210

1. add_compile_option

I have the same issue, I have a snapdragon 8 gen 2, I believe it's armv9a, same as 7 gen 2. May I know why you tell it's "mcpu=cortex-a35 -march=armv8.4a+dotprod?" a35 is quite old, and shouldn't be something like -march=armv9a?

Problem solved for new Snapdragon (armv9a) thanks to this thread:
#402

Find the directory the CMakelists.txt file is in (should be main dir) and run the following line:

sed -i 's/add_compile_options(-mcpu=native)/add_compile_options(-mcpu=native+nosve)/g' CMakeLists.txt

Snapdragon 8 gen 2 gives me 110ms per token for 7B Q4_K_S and -t 5
