This means that OpenCL is not setup in your Termux environment.
Meaning that the library gets loaded but it's not able to talk to the driver. So the very first OpenCL call that we make to try to query platform ID fails. Maybe try running the app natively (via adb).

In fact, I have enabled opencl.
LD_LIBRARY_PATH=/vendor/lib64:$PREFIX/lib
I need to set PATH to make llama.cpp use the system driver.
