Description Ben Boeckel 2020-02-05 18:34:55 UTC

SUMMARY

It appears as though KDevelop is still relying on CMake's server mode.  The server mode was superseded in CMake 3.14 by the file-api.  Furthermore, the server mode was deprecated in CMake 3.15 and will soon be removed.  KDevelop should be updated to use the file-api instead.  Doing so may also address some of the other CMake-related issues that are open.

sigh yes very true... thanks for reminding us.

I've started working on this now over at https://invent.kde.org/mwolff/kdevelop/commits/cmake-file-api

Comment 3 Milian Wolff 2020-02-09 21:13:57 UTC

OK, the branch is now ready for testing. There are some things left to be done, most notably support for runtimes (docker etc). I'll also have to test it on a real world project outside the unit tests now.

Start implementation of cmake-file-api support

Before long, upstream cmake will remove the server support. Instead,
the new cmake-file-api is supposed to be used. This patch adds the
first baby steps towards that goal. We now write a query file to
the required location before running the cmake configure job. Then
we can look for the latest available index reply file that belongs
to our client request.

Actually parse the cmake-file-api response files

For now, this is only done in the unit test. We are also lacking
support for runtimes, as I first want to clarify how this is
supposed to be done and tested.

Actually use the cmake-file-api for project import, if possible
