Hi,
I have followed instruction and some tips from forum, but I’m getting error during compilation. Runtime requires libLLVMCoverage, and there is no instruction for compiling it. My commands:
# copy cmake config
cp cmake/config.cmake build-arm-api-28
# goto build dir
cd build-arm-api-28
# set LLVM from $ANDROID_SDK
sed -i 's/set(USE_LLVM OFF)/set(USE_LLVM \/home\/piotr\/Android\/Sdk\/ndk\/21.3.6528147\/toolchains\/llvm\/prebuilt\/linux-x86_64\/bin\/llvm-config)/g' config.cmake
# rum cmake

After few minutes I’m getting following error at the end of whole compilation:

–edit–
I have search for this file, only found in /usr/lib/llvm-9 file LibLLMVCoverage.a.
During compilation, there was error about missing headers, so I have linked headers from system-installed llvm in version 9 (I have linked system-installed llvm to android-sdk llvm include folder).
My cmake version 3.10.2
