Remote debugging with QtCreator

[Veepee]

I have established a ssh connection between target device and my Desktop PC Ubuntu 14.04.
I have the debug binaries flashed on to the target .

I have started gdbserver in my target device with port 2345 for my executable.
To start remote debugging in Qt creator I give
Debug->STart Debugging->Attach to running debug server

I get the below error on starting the debug

Error:
Debugging starts
Could not load shared library symbols for linux-gate.so.1.
Do you need "set solib-search-path" or "set sysroot"?Debugging has finished

Gdbserver version in target:
GNU gdbserver (crosstool-NG 1.21.0) 7.10

Desktop details:
Ubuntu 14.04
Qtcreator version 4.0.1
Qt 5.6.1

Configuration in Qtcreator for gdb:
Additional attach commands ( gdb of Qtcreator)
set solib-search-path /home/XXX/xxx/xxx_GEN/xxx/generated/staging/xxxx86make/usr/lib/:/home/XXX/xxx/xxx_GEN/xxx/generated/bin/xxxx86make/debug/
set handle SIG32 noprint nostop
set handle SIG64 noprint nostop
set detach-on-fork on

Sysroot path is set in Build & Run configuration of Qtcreator.

I find linux-gate library is a dynamic virtual lib that is embedded as part of the binary. Any idea why this is not loading ?

@Veepee said in Remote debugging with QtCreator:

linux-gate.so.1

it can depend on other libraries.
What does "ldd linux-gate.so.1" say?

[Veepee]

I cannot give ldd linux-gate.so.1 because linux-gate is a virtual dynamic lib and does not exist in the system

ldd linux-gate.so.1

ldd: ./linux-gate.so.1: No such file or directory

[Veepee]

This looks to be an issue with gdb 7.7.1
The issue gets resolved when I upgrade to 7.8 or later.

@Veepee Regarding your use of the ldd - you need to pass the whole path to the library so it can actually find it...
