You did not answer my initial question:
which workspace type are you using?

Sorry I missed this. Normal C++ workspace that I created with 14.x (Probably earlier version)

CodeLite 15.x
CodeLite is awesome, I just Love it!

But you mentioned "CMake generated folder"
Is this a custom build project?
can you paste here the build output?

Make sure you have read the HOW TO POST thread

OK so here is how I generated the whole thing.
I created C++ project with CMake as generator
CL generated for me relevant CMake files
I removed comments so that CL does not autogenerate CMake files (.*tx) because I did a lot of hand editing.

I'm not sure that fits the definition of Custom.
But may be I removed some important CMake instructions related to Autocomplete?

When using CMake plugin, the default Makefile generators are not working, this means, that the mention files are not created by CodeLite. It is custom in the meaning that CodeLite does not generate the Makefiles.

Somewhere at the top of your main CMakeLists.txt make sure that this line exists:

Code: Select all

set(CMAKE_EXPORT_COMPILE_COMMANDS ON)

and somewhere at the bottom of the same CMakeLists.txt, have this:

Code: Select all

execute_process(COMMAND ${CMAKE_COMMAND} -E create_symlink ${CMAKE_CURRENT_BINARY_DIR}/compile_commands.json 
                ${CMAKE_SOURCE_DIR}/compile_commands.json)

The first command, tells CMake to generate compile_commands.json, the problem is that this file is generated at the build folder (e.g. build-debug)
the second commands, adds a symlink from the source directory to the generate compile_commands.json file so clangd is able to pick it up

I have done that and now the JSON file is generated. Completion still not working though.
I will review the log and see if there is anything I can fix there!
