ocl-icd

[suleymanemre]

Sorry I am new at compiler field. Thankl you for your time. I tried to download ventus LLVM Compiler. I got an output like this, but I didn't understand whether the process was completed or not. If I need to build ocl-icd, should I do it in the file I downloaded? Doesn't the script file do it automatically?

Please build ocl-icd first!

Another question,

/Ventus_Compiler/llvm-project/build/lib in this directory there is no libpocl.so so I cannot link icd driver like given below.

Run export OCL_ICD_VENDORS=${VENTUS_INSTALL_PREFIX}/lib/libpocl.so to tell ocl icd loader where the icd driver is.

Firstly we need to config, make and make install to ocl-icd (you can take a look at readme file in ocl-icd directory)

$cd ocl-icd
ocl-icd$ ./configure

after configure you need to call make in ocl-icd directory

suleyman@DESKTOP-UD9KE8O:~/Ventus_Compiler/ocl-icd$ make
ruby icd_generator.rb --mode database --database ./ocl_interface.yaml \

/bin/bash: ruby: command not found
make: *** [Makefile:1660: stamp-generator] Error 127

If you see error something like this

sudo apt install ruby

after that you can make ocl-icd

ocl-icd$ make

after make command just make install in ocl-icd

ocl-icd$ sudo make install

after building ocl-icd you can back to llvm-project file and

llvm-project$ bash ./build-ventus.sh
