Remote debugging fails with a cryptic message
-
Hi,
I'm familiar with remote debugging and using it for a long time. I've tried to install a virtual machine for conducting some test in it. Unfortunately the debugging fails at the beginning.
gdb and gdb-server are already installed on the target, test on the Device page completes successfully (so, gdb-server, rsync, ssh everything works as expected).
Here's the console output:
12:16:30: Checking available ports... 12:16:30: Found 51 free ports. 12:16:30: Starting gdbserver --multi :10000... 12:16:30: Debugging /opt/******/*******/****** ... Listening on port 10000 Remote debugging from host ::ffff:192.168.1.27, port 38884 Process /opt/******/*******/****** created; pid = 1654 while parsing target description (at line 68): Vector "v8bf16" references undefined type "bfloat16" Could not load XML target description; ignoring Killing process(es): 1654 12:16:31: Application finished with exit code 0. 12:16:31: Debugging of /opt/******/*******/****** has finished with exit code 0.Target OS is Debian Bullseye (11) amd64 and I'm using Ubuntu 20.04 amd64 as host OS. Qt version is 5.15.2
I even can't find the XML file which is mentioned by the error message. I'm guessing a Clang related hidden mumbo jumbo is going on in the background, but don't know how to solve it.
Regards,

@MuratUrsavas I know it is a very old post, but I’m currently facing the same problem. Did you found a solution?

Bumping this report to the top. Was there any resolution as to the cause of the error. I have a new application which now fails to remote debug using the same procedure we have used for years. I get this very same message:
11:02:03: Debugging /home/michael_uman/gitroot/build-udevwrapper-Desktop_Qt_5_15_2_GCC_64bit-Debug/udevwrapper ... while parsing target description (at line 71): Vector "v8bf16" references undefined type "bfloat16" Could not load XML target description; ignoring Unable to find dynamic linker breakpoint function. GDB will be unable to debug shared library initializers and track explicitly loaded dynamic code.Any assistance would be greatly appreciated.
Thank you,

I am using crosstool-ng-1.25.0 as my toolchain.
Host uBuntu 20.4 64bit Qt5.12.8 QtCreator 4.11.0
RasPi CM4 Debian12.6 64bitSet GDB on the host to /bin/gdb-multiarch
This was installed with sudo apt-get install gdb-multiarch.
When I started debugging with this setting, a message similar to the poster's was displayed.I reset the GDB on the host to ~/x-tools/aarch64-rpi4-linux-gnu/bin/aarch64-rpi4-linux-gnu-gdb (Binaries built with crosstool-ng) and re-ran, and it ran normally without terminating the process.
Is this helpful?
