[User] Android build fails with "ld.lld: error: undefined symbol: clGetPlatformIDs"

[Mabbs]

Prerequisites

Please answer the following questions for yourself before submitting an issue.

• I am running the latest code. Development is very rapid so there are no tagged versions as of now.
• I carefully followed the README.md.
• I searched using keywords relevant to my issue to make sure that I am creating a new issue that is not already open (or closed).
• I reviewed the Discussions, and have a new bug or useful enhancement to share.

Expected Behavior

I am trying to use this tutorial to compile llama.cpp.

Current Behavior

Compilation failed.

What's the output from apt install libopenblas ?

Edit: I think I reproduced your problem.

Try this:

pkg install libopenblas
pkg install clblast

And run make again.

I get the same error but even after running these commands, it still persists.

@staviq any ideas on what else could be the issue? Everything else from the original bug report is the same. Just trying to go through the tutorial and getting this error on the make LLAMA_CLBLAST=1 command.

[nmeln]

@miketdn Try running this as well: pkg install package-config.
make was complaining about package-config not found, and it's easy to miss that error. After I installed it, the compilation was completed without errors.

[miketdn]

@nmeln Thanks for the suggestion but I get Unable to locate package package-config. I tried a couple of different repos, but no luck. Is there a repo I should use in particular?

[romanovj]

pkg i pkg-config

[nmeln]

@miketdn Yes, I used an incorrect name, look at @romanovj reply for a correct command.

Another thing is at least on my device (Qualcomm SM8150 Snapdragon 855+) I'm getting gibberish and very slow output when compiling with clblast support.

If you find that to be the case as well, I would recommend just cloning the llama.cpp repo and running make and ignoring other instructions from the readme.

Here are my settings for example (I set gpu offload to zero):

./main -m ./models/3B/stablelm-zephyr-3b.Q6_K.gguf -t 4 -ngl 0 -n -1 -c 1024 --repeat-penalty 1.0 --top-k 0 --top-p 1.0 --min-p 0.05 --temp 1.6 --rope-freq-base 0 --rope-freq-scale 0 --color -i --interactive-first --in-prefix "<|user|>\n" --in-suffix "<|endoftext|>\n<|assistant|>" -r "<|user|>" --keep -1 --prompt "This is an infinite conversation between a helpful assistant (you) and the user (me). You provide consistent and short replies. When faced with a specific problem, you will first identify and write out the constraints specified by user, then reason step by step to solve the problem."

@ggerganov Could these commands be added to the README ?

[miketdn]

Still doesn't work after running pkg i pkg-config successfully. Still the same error message as the original report:
ld.lld: error: undefined symbol: clGetPlatformInfo

[romanovj]

Still doesn't work after running pkg i pkg-config successfully. Still the same error message as the original report: ld.lld: error: undefined symbol: clGetPlatformInfo

do you have ocl-icd?

pkg i oci-icd

maybe you need to add to LDFLAGS
-L/system/vendor/lib64 -lOpenCL

[miketdn]

@romanovj Yes, I'm following this section of the README (https://github.com/ggerganov/llama.cpp#building-the-project-using-termux-f-droid).

I ran these two initially:
apt install libopenblas
apt install ocl-icd opencl-headers opencl-clhpp clinfo

They were all installed successfully. I think there must be something wrong with my phone/OS or with the instructions because I re-tried on a new phone, new installation and still get the exact same errors. I've also tried all the suggestions noted here, no luck unfortunately.

I originally tried on a Pixel 6 running GrapheneOS. Now tried on a brand new Pixel 8 running GrapheneOS.

Try running pkg upgrade and apt update && apt upgrade in the new phone's Termux

I run the apt commands you mentioned, but also:

pkg install clang wget git cmake
pkg install libopenblas
pkg install clblast
pkg install pkg-config

And have compiled clblast and copied the required header file and so file as specified in the readme.

Then exited and restarted Termux.

Additionally I copied openblas headers to llama.cpp folder (make sure you are in the right dir)
