@cristian-adam You're a lifesaver!

I just installed your toolchain and was able to debug my Qt 5.15 / 32bit programs again.

In my opinion, a current 32 bit MinGW toolchain should be delivered with the online installer.

We are using 32bit 3rd-party libraries (GPIB-32.dll) so switching to 64bit is currently no option.

Thanks again and best regads

I have the same problem but I'm using MSVC most prolly cdb has same problem but is there a way to fix it?

Edit: Toolchain Windows 11 Pro 23H2, Kit -> Qt 5.15.17 MSVC 2019 32-bit

For CDB Qt Creator 14 doesn't come with the 32 bit dll that's used by x86 cdb to load the project.

As it turns out the 64bit cdb, which is supposed to handle both x86 and x86_64, doesn't really work with 32 bit program.

but it was working fine when I was using Qt Creator 13.0.2.

You can still use Qt Creator 13.0.2 for that.

Qt Creator 14 has removed a component and this causes issues.

@Vdeilae Is there a way to downgrade to 13 using the online installer? I don't want to install the standalone version.

I am having the same problem while using QT.6.7.2 and MinGW 11.2.0 for 64x. Since my gdb is already a newer version. I think I should'nt face the same problem but I do actually. I also checked if gdb is running python code:

PS C:\Qt\Tools\mingw1120_64\bin> ./gdb

(gdb) python print("Python 3 is working")
Python 3 is working

Any suggestions?

@EmirhanPolat: Please have a look in View > Views > Debugger Log.

PS: To really check the Python version, use something like python import sys; print(sys.version)
