[Srinivas Kakarla1 via cfe-dev]

Hi ,

I made some progress ,But I encountered the below error(  llvm-size not found).

cmake --version 
cmake version 3.14.0-rc3

cmake -DCMAKE_C_COMPILER=/usr/bin/clang         -C../test-suite/cmake/caches/O3.cmake         ../test-suite
loading initial cache file ../test-suite/cmake/caches/O3.cmake
CMake Error at CMakeLists.txt:92 (message):
  llvm-size not found.

  Make sure it is in your path or set TEST_SUITE_COLLECT_CODE_SIZE to OFF


-- Configuring incomplete, errors occurred!
See also "/test-suite-build/CMakeFiles/CMakeOutput.log".
See also "/test-suite-build/CMakeFiles/CMakeError.log".

Can you please check the error , logs and let me the issue.

Hi ,

Here is the error info and log.
Please check and provide the solution.

cd test-suite-build/$ cmake -DCMAKE_C_COMPILER=/usr/bin/clang         -C../test-suite/cmake/caches/O3.cmake         ../test-suite
loading initial cache file ../test-suite/cmake/caches/O3.cmake
CMake Error at CMakeLists.txt:50 (message):
  In-source builds are not allowed.

  CMake would overwrite the makefiles distributed with LLVM.

  Please create a directory and run cmake from there, passing the path

  to this source directory as the last argument.

  This process created the file `CMakeCache.txt' and the directory
  `CMakeFiles'.

  Please delete them.
