You probably just need to nuke the build folder. The reason for that is that before the patch the LLDB_TEST_C_COMPILER variable was used for a different purpose (and usually empty), where as now it's set by default to the in-tree clang. However, cmake will not overwrite the cached value by design. (I could have worked around that in cmake, but I only noticed that issue after landing the change.)
Erasing the build folder should let the new and correct default kick in. If you run the check-lldb target then it will now use the in-tree clang instead of the system compiler for using tests. sorry about the trouble, pl On 7 November 2017 at 18:21, Jim Ingham via lldb-dev <lldb-dev@lists.llvm.org> wrote: > The lldb_cmake GreenDragon bot is now failing, e.g.: > > http://lab.llvm.org:8080/green/view/LLDB/job/lldb_cmake/1703/consoleFull#589016626e9a0fee5-ebcc-4238-a641-c5aa112c323e > > This looks related to Pavel's change: > >> r316728 | labath | 2017-10-26 19:24:04 -0700 (Thu, 26 Oct 2017) | 18 lines >> >> Default to using in-tree clang for building test executables >> >> Summary: >> Using the in-tree clang should be the default test configuration as that >> is the one compiler that we can be sure everyone has (better >> reproducibility of test results).
