CLion 2019.3 EAP: Fixes for CMake Generators, Disassembly, and More


A new CLion 2019.3 EAP (build 193.4778.13) is now available! Get it from our website, via the Toolbox App, or as a snap package (if you are using Ubuntu). A patch-update for anyone using the previous EAP build will be available shortly.


Generators in CMake

In the recent EAP build, we’ve added support for Ninja and other generators in CMake. We’ve had tons of valuable feedback and discovered cases we hadn’t tried on our side! It was great that, with your help, we were able to catch all these problems and we have worked hard over the week to fix the most annoying ones. Today’s build brings a few important fixes:

  • On Windows, an exception was caught that could prevent your project from correctly loading CMake and the project build (CPP-17728, CPP-17740).
  • For any generator which is not Makefiles (default) or Unix/MinGW/MSYS Makefiles, the custom make path in the Toolchains settings is ignored now. This was preventing Ninja from working correctly (CPP-17749). Later, we plan to allow users to specify their custom build tool in this field, for example, any custom Ninja version (CPP-17773).

Experimental debugger for MSVC

Some users noticed that the experimental debugger for the Microsoft Visual C++ toolchain had stopped working in the recent EAP build. Now, it’s fixed and back again. We are sorry for any inconvenience this may have caused!

Other fixes

A few issues with disassembling on Windows were fixed (CPP-15210, CPP-15828, CPP-17115).

Besides, there are some VCS improvements coming from the IntelliJ Platform.

The full release notes are available here.

    I really don’t understand, we can’t add a python interpreter because all the folders will have python icons.
    The other solution is to mark the python files as plain texts, which is also not good.
    When will be this regression fixed? in 2019.2.3 works perfectly.

    The bug is CPP-17645, very similar to CPP-17509, which is marked as fixed, really?

    • Anastasia Kazakova says:

      The CPP issue is marked as fixed because it’s a duplicate of When PyCharm ticket is closed, the problem is solved. We keep an eye on it, and we chat with the PyCharm team to fix the issue.

      • Taw says:

        I am not that optimist because in the bug it’s written
        “All directories for Python 3 are namespace packages, therefore they have Python package icons. So the actual bug is that in case #2 there are no dot icons for all the directories.”

        So it’s actually correct that every directory will have a dot? Perhaps I am not understanding correctly, but I have one py file in my CLion project and ALL my folders (containing mostly .c and .h files) should have dots?

        • Anastasia Kazakova says:

          The dot appears only when you are adding an interpreter and it’s definitely a bug, and it’s exactly a bug described in the PY issue.

          • Tano says:

            Thank you for the nice explanations in the tasks, Anastasia.
            My colleagues always laugh at me that I will receive a JetBrains call “We will find you and we will kill you” 😀

          • Anastasia Kazakova says:

            No problem. Hope it’s now indeed clear. And we definitely work in the direction of fixing the issue.

  2. Taw says:

    I have also a question about IDEA-223210.
    Is this a bug or someone thought that it will look better? (sorry on the task I got no answer for a month)
    I really want to revert to the old behaviour (with paranthesis), if possible, maybe a hidden option or something, thank you.

  3. Roman Popov says:

    Had to switch back from Ninja to Makefiles. Found out that for Ninja project all .cpp files have : “No resolve context for current file”, which breaks Google Test integration (CPP-15903) and shows lots of false positive “Unused global variable”

    • Anastasia Kazakova says:

      Roman, would be great to investigate the case with you in details. As I see from the issue now there is some performance issue involved.
      I honestly don’t think it’s somehow related to CMake API and thus Ninja, but more like some other problem, which is definitely have to be investigated. We’ll do our best. Thanks for the cooperation.

      • Roman Popov says:

        I spent whole day on it yesterday. But have not found any way to analyze it. Today I work on Windows, and here it did not reproduced itself yet.

        Basically what I need from Clion is to provide more debug information. If it shows it should explain me why.

  4. Roman Popov says:

    Tool-chain settings still do not work on Windows with Ninja. Had to set -DCMAKE_CXX_COMPILER manually

    • Anastasia Kazakova says:

      Not sure what do you mean here. Can you please provide more details?

      • Roman Popov says:

        If I do not set CMAKE_CXX_COMPILER CMake will use Mingw instead of Visual Studio. Despite I have Visual Studio toolchain configured.

        • Anastasia Kazakova says:

          Am I right you have VS toolchain used in your active CMake Profile? Do you use the latest EAP build with the fixes?

          Can you please reset CMake cache, remove CMake generated output directories and reload the CMake Profiles for your project? (Maybe after the issue you had on the previous build, some information is just stuck in CMakeCache and similar)

  5. Helge Penne says:

    The EAP freezes while editing code. I have uploaded logs with the bug report: CPP-17871
    Please investigate.

  6. Przemysław Sztoch says:

    1. Memory View should be upgraded!!!
    Please, check Visual Studio or other IDE as template!!!

    2. Peripherals view should be with Favorite item feature.

    3. Peripherals view should have new RMB action: Copy Address.

  7. Helge Penne says:

    Is it just me, or did this EAP break keyboard input for the “~” character? On my Norwegian keyboard, this is AltGr combined with the key left of Enter and below Backspace. It produces the ~ in all other programs, but in CLion it just produces a space.

    This is a completely fatal bug, as I am no longer able to type out a destructor.

    Please fix ASAP!
