Qt Creator fails to recognize the GDB whose version output contains extra numbers

novum

Qt Creator cannot parse the GDB version string because it contains additional version information (from crosstool-NG), causing ABI detection to fail.

So it's a Qt Creator issue. The version string contains extra stuff that trips the parser. Hence the wrong version shown in the dialog.

I created QTCREATORBUG-34887 to track it.
Patch in progress.

Both GDBs are built by crosstool-NG. Their version output is as follows:

./aarch64-linux-gnu-gdb --version
GNU gdb (crosstool-NG 1.29.0_rc2) 17.2

The only difference is the text inside the parentheses -- one say 'crosstool-NG 1.29.0_rc2', the another says 'GDB'.

Hi,

What output do you get if you call each of them with --configuration ?

The 'crosstool-NG' GDB output is shown as follows:

./aarch64-linux-gnu-gdb --configuration
This GDB was configured as follows:

tree, and GDB will still find it.)

Patch integrated :-)
If you need it earlier, you might want to consider building the debugger plugin for your version of Qt Creator. If not Qt Creator itself directly.

aha_1980

Or to add to @SGaist: Use one of the next snapshots from: https://download.qt.io/snapshots/qtcreator/21.0/21.0.0-beta1 which will contain the fix.

@aha_1980 good point ! I did not think of the snapshots.
