I’m also using V1.0.0 of cursor and enabled C_Cpp.intelliSenseEngine but still can,t use jump to.
Before that, I followed this [link](https://forum.cursor.com/t/after-installing-the-c-c-extension-from-anysphere-platformio-ide-is-not-activated/97778/14) solution, but still can’t work. It’s too bad
Posting in case this helps anyone. I also posted a similar reply to a python-related thread. I had the same issue with C/C++ code after migrating to a new (raspberry pi) dev server. Syntax highlighting was very basic, and all of the context sensitive/Intellisense features were gone. The right click menu did not show ‘go to definition’ and F12 did nothing.
My issue was that I did not have the clangd language server installed. I believe this is needed for the C/C++ extension from Cursor. If you’re having this problem it might be worth checking with:
which clangd
You should see something like /usr/bin/clangd
If you don’t, you can install by following the instructions at Getting started
For Rpi, Debian/Ubuntu:
sudo apt search clangd
As of writing, clangd-19 is the latest.
sudo apt install clangd-19
You will need to point ‘clangd’ to ‘clangd-19’ still.
