[Qt-creator] [Fwd: Re: BareMetal Target Plugin Configuration]

[Jeandet Alexis]

Hi Freddie,

As a complement to what I send to Tim yesterday, here is a link to my
kit. It's still under development and far away to be releasable!
ftp://ftp.lpp.polytechnique.fr/jeandet/keep/libuc2.tar.bz2
If anybody want to have a look at it, it works only on linux_x64 and if
you put it in /opt/libuc2 then you can add this as Qt kit from creator.

In my understanding the run setting is the place you start your gdb
server with all the options (gdb port address), a good feature could be
to add it automatically from a wizard or the Bare metal plugin.

best regards,
Alexis.

Hello Tim, 
Thanks for your answer. I am already quite familiar with debugging on
stm32 with gdb, I have one setup with nemiver which works fine. From
what you explain me, it seems that my configuration was good so after
more investigations, the problem come from my custom Qt kit. In fact
this is not just a fake SDK, it contains a qmake with customs mkspec
files and libraries for arm(MMUless) processors, that's why I use it.
I made it to allow users to create simple qt projects for boards like
STM32F4* without big modifications in the .pro file all the gcc and lib
configs are in my kit.

It seems that Qtcreator needs to detect the kit's abi to setup the gdb
client which seems weird to me because you can tel it which gdb to use.
In my case I tried a funny thing, I copied a random lib file from my
folder to Mykit/bin/libQtCore.a and then qtcreator detect my kit as
arm-linux-generic-elf-32bit instead of amr-unknown-unknown-unknown-32bit
the detected ABI for the used gcc and gdb.

Is there any thing possible on Qtcreator side to have a more flexible
kit detection? I didn't plan to switch to QBS for now, I don't know yet
if it can replace what I do with my custom kit and qmake?

best regards,
Alexis.
