[lldb-dev] LLDB Assertion failed

[Ted Woodward]

My guess would be the change that switched from shell scripts to python files to configure swig.

I think the problem is in source/CMakeLists.txt, specifically this line:

                COMMAND ${PYTHON_EXECUTABLE} ${CMAKE_CURRENT_SOURCE_DIR}/../scripts/finishSwigWrapperClasses.py --buildConfig=${CMAKE_BUILD_TYPE} "--srcRoot=${LLDB_SOURCE_DIR}" "--targetDir=${CMAKE_CURRENT_BINARY_DIR}/../scripts" "--cfgBldDir=${CMAKE_CURRENT_BINARY_DIR}/../scripts" "--prefix=${CMAKE_BINARY_DIR}" "--cmakeBuildConfiguration=${CMAKE_CFG_INTDIR}" -m

The problem is "--buildConfig=${CMAKE_BUILD_TYPE}". If CMAKE_BUILD_TYPE is not set, you call finishSwigWrapperClasses.py with "--buildConfig=", which breaks the script. In my local Windows build I changed CMAKE_BUILD_TYPE to CMAKE_CFG_INTDIR. I don't know if that's correct, but it fixed my build calling the swig scripts.

Can you point out the change that caused that? I encountered the same issue and I’d like to take a look.
