Remote Debugging

[ODБOï]

Hi,
I'm trying to deploy a debug build of my application on my target machine, start it and use my development PC (qt-creator) to debug the application remotely.
-target machine runs windows10 (no Qt installed)
-dev machine windows 10, Qt5.15 - mingw

I follow instructions from here:
https://doc.qt.io/qtcreator/creator-debugger-operating-modes.html#remote-debugging

So i manually copied the content from my dev PC c:\qt\tools to my target PC
then i try to run my application (debug build) like this :

gdbserver :1234 myAppDbg

but i get this output

glob could not process pattern '(null)'

Does someone know what is the issue pls ?
Thank you

@JonB Hi, thank you very much for your time.
If i understand correctly there is a patch that i can apply togdbserver to fix this behavior ?
Do i have to build gdbserver myself to apply that patch or i can download binaries from somewhere ?
THX

@LeLev
I know no more than what those links said!
Start with gdbserver --version on your system?

@JonB said in Remote Debugging:

Right now i have version 8.1, but a also did a test with one older version (7.something)

@LeLev
My reading is that it was fixed on 8.1.1 (I believe). Can you get a later version than your 8.1?

[ODБOï]

@JonB ok thanks.
I will try to download the last version then.
My current version is the one that comes with Qt installation, under tools folder.

Hi
Where can I download gdbserver (binary) version >8.1.0 for windows ?
GDB is included in MinGW installation package but the most recent version there is 7.x
The vesion i got with Qt Maintenance Tool is 8.1.0
Should i maybe build the last version myself ? Where to find sources and build steps for windows pls ?

THX

Is there really no way of getting a compiled version directly ? I searched everywhere
