[lldb-dev] Trouble with ScriptInterpreter unit tests
Hi there, I've been working on a patch for LLDB but have been having an issue running the test suite (even on a clean checkout of trunk) where the ScriptInterpreter tests are hitting SIGSEGV. From what I understand, the unit test involves an embedded Python interpreter and it's happening when we try to import the LLDB module. I was wondering whether anyone has encountered this before. I'm new to LLDB and LLVM in general so I figured I'd check if there's something obvious I'm doing wrong before going too far down the rabbit hole. In case it's important, my CMake and Ninja invocations look like this: cmake -G Ninja -DCMAKE_BUILD_TYPE=Debug -DLLVM_ENABLE_ASSERTIONS=ON -DLLVM_ENABLE_PROJECTS="clang;lldb;libcxx;libcxxabi" -DCMAKE_CXX_COMPILER="g++-5" -DLLVM_PARALLEL_LINK_JOBS=1 -DBUILD_SHARED_LIBS=ON ../llvm LD_LIBRARY_PATH=/home/alexc/work/llvm-project/build/lib ninja check-lldb-unit And each stack trace looks like this: [==] Running 1 test from 1 test case. [--] Global test environment set-up.
