Building clinfo on Termux Android #46
Description
Hi, this is just an appreciation post for clinfo and
a build instruction for building clinfo on Termux that runs on Android.
It should allow people to investigate OpenCL on 64bit Android devices.
You need to have /system/vendor/lib64/libOpenCL.so present on the device.
If the Android device doesn't have this, it most like doesn't have OpenCL and the build will fail.
Something like cannot find -lOpenCL
I am going to close the issue since its not an issue with clinfo.
Simply install Termux from Google Play or FDroid
Run these commands:
pkg install git make clang -y
cd ~
git clone https://github.com/Oblomov/clinfo
git clone https://github.com/KhronosGroup/OpenCL-Headers
cd ~/clinfo
export LD_LIBRARY_PATH="/system/vendor/lib64:/system/lib64"
export CFLAGS="-I$HOME/OpenCL-Headers"
export LDFLAGS="-L/system/vendor/lib64"
make
./clinfo
