Unable to inspect the STL containers during debug

I have a problem inspecting any kind of stl containers.std:string, std:vector , everything I have tried I can't inspect the contents.

Following this https://blog.jetbrains.com/clion/2015/02/clion-eap-news-cmake-3-1-stl-renderers-in-debugger-pty-and-more/  it is supposed that I get a pretty render of a container

which is exactly what I was expecting.

In my case though it seems that I get the raw contents of the vector.Here is what I get

I use MinGw in Windows 10 and cmake.

I am sure that I am missing something fundamental.But I spend the whole day trying to figure out what I am missing.Any ideas?

Hi,

To share my complete findings: I've already tried 5 Windows toolchains, here is which print the STL collections nicely:

  • MSVC 2019 - OK (but you have to select the Visual Studio, not the build tools as the toolchain)
  • MSVC 2019 Preview - OK
  • MinGW 64 official SourceForge toolchain - OK
  • MinGW 64 from Nuwen - NOT OK (because it is built without Python support)
  • MSYS2 - OK

Hope it helps!

David Fido Fiedler thanks a lot for sharing! 

As for "MSVC 2019 - NOT OK": do you have a complete Visual Studio installation or VS19 BuildTools?

Anna Falevskaya I have a full Visual Studio Community 2019 installation, version 16.5.5

David Fido Fiedler that's strange. Please send examples of particular cases which doesn't work or a simple project with which the issue can be reproduced to clion-support at jetbrains.com, we will investigate it.

From my side I cannot give any updates as we decided to migrate out build env back to debian. Now we can use gdb 8.2.1 and it works fine.

I cannot check lldb, because we deleted it from our building images.

I had the same issue, testing several versions of MinGW64. The problem is fixed installing python2.7 on my machine.

Anna Falevskaya Yes I had NatVis rendering enabled.

I was using VS Studio 2017 Community.

Using MinGW-w64 8.3.1 gives the same result.

Anna Falevskaya It turns out that VS 2019 Community build tools work, but not 2017, so the problem is solved for me. MinGW-64 - the version you linked and the one from the page from Clion's download button - do not work on Win10 with most recent Clion.

Same problem here with latest mingw-w64 posix seh x86-64 build from SourceForge and CLion 2020.3. David mentioned earlier that MSVC builds generally seem to work. Is there a way to download them separately, or do I have to install the IDE as well? Also, any other workarounds / toolchains that work?

The same issue happened to me. It worked after I unchecked "Enable GNU C++ library renderers" in Settings.

@... My environment is the same as yours. When debugging in clion 2019.3, I can see the real value in the vector. After upgrading to clion 2020.3, something went wrong, but it is still normal in vscode.

@... My problem is solved using your method, why does it work?

@... we have a regression in CLion 2020.3 with MinGW - https://youtrack.jetbrains.com/issue/CPP-23244. Disabling "Enable GNU library renderers" is a workaround.

We are working on the issue right now. Feel free to comment or upvote the issue in order to get updates. See https://intellij-support.jetbrains.com/hc/en-us/articles/207241135-How-to-follow-YouTrack-issues-and-receive-notifications if you are not familiar with YouTrack.

Sorry for the inconvenience.

I'm having the same issues on macOS. I have disabled "Enable GNU library renderers", but I'm still experiencing the same issue.

From File -> Settings -> Build, Execution, Deployment -> Debugger -> C/C++ -> uncheck Enable GNU C++ library renderers as shown in the below screenshot. STL containers are now visible.

I had the same issue. CLion version 2022.2.1. I re-added the MinGW tools in File -> Settings -> Build, Execution, Deployment -> Toolchains. Because of this, I had to rebuild the configuration. After that, everything showed up again. At the same time, a check mark is set in File -> Settings -> Build, Execution, Deployment -> Debugger -> C/C++ -> uncheck Enable GNU C++ library renderers
