I am on the latest version, cursor is unusable for c/c++ developments on my ubuntu system, have to resort to using vs code, as microsoft extensions are no more working, and the above issue w.r.t ctrl + func_call still exists

Hi @Sourav_Kumar,

Microsoft C/C++ extensions are not supported in Cursor. You need to use the Anysphere C/C++ extension instead.

To install:

  1. Open Extensions view (Ctrl+Shift+X)

  2. Search for “Anysphere C/C++” or extension ID: anysphere.cpptools

  3. Install it

Can you try this and let me know if the extension installs successfully and whether it resolves your issue?
