LLVM and LIT Issue

Hi ,

I was trying to compile the CLANG LLVM and LIT setup.

I am following the below steps.

1.https://llvm.org/docs/TestSuiteGuide.html // LIT Setup
2.https://clang.llvm.org/get_started.html // LLVM setup

My system got hanged during LLVM compilation ( system configuration i5 8gb RAM,500 HDD).
I tried in another system also same problem.

Ubuntu also crashed after force reboot.I could able to send any logs and error .

Can you help me to setup LLVM and LIT.


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.
