QT 5.14.2 Windows 10 -> Clang Code Model: Error: The clangbackend executable "C:\Qt\Tools\QtCreator\bin\clangbackend.exe" could not be started (timeout after 10000ms)

[Olivier69]

I have this error message at start up and the check/uncheck do not give better result (solution see on this forum). When uncheck the error message do not show naturally ;)

The Qt is on a windows 10 installed on a mac mini with bootcamp. Don't know if that can help.

I start a project with exemples that compile but crash after so I would to correct this to be sure that are not the causes.

I had that problem too. You need to change your settings of an application Output panel which is at the bottom of the screen. Build & run ---> General ---> Default for "Run in terminal" (change this option from disabled to enabled). After this qt works normally.

For me it didn't work I got the error message when it hits any breakpoint, any other sugestions?

@Claoo @Olivier69 Same issue here using QT in windows 10.

I had it working two months ago, i came back and now every time i try to debug in android:
Clang Code Model: Error: The clangbackend executable "C:\Qt\Tools\QtCreator\bin\clangbackend.exe" could not be started (timeout after 10000ms).

• So i updated my android SDK, same problem.

• So i did what @fadfa suggested ("run in terminal" enabled) still the same problem.

• So removed spaces in my filepath, still the same problem.

In my Issues tab inside QT creator, after i try to run my app;

@javiB i checked the first error
So something went wrong in the build process i guess?

Maybe my path name is so long it makes the build process (GetFullPathName) to fail.

that was it, i changed the build folder to my desktop (shorter fileath names) and everything worked
