OK I solve this problem, it is really stupid. It is caused by my unfamiliarity of clion ide.
When I'm using Clion IDE, It will set up a doc called "/cmake-build-debug". It's like our file "/build". However , it lack of the file "config.cmake"  I noticed that Cmake in Clion doesn't support llvm , so I copy config.cmake from file "build", and paste it in "/cmake-build-debug". And use direction like we do in "/build": **cmake ..** **make -j20** **make cpptest** and then, It works and no bug in clion debugger!  I know it is a simple problem, but I hope this will help when other guy use IDE! :grinning: --- [Visit Topic](https://discuss.tvm.apache.org/t/cpptest-build-module-test-cc-check-failed/11881/7) to respond.
