Hello
We have compiled meta-toolchain-qt (Yocto dylan). Now we can run
QT applications on Desktop (Ubuntu 12.04) and on target (iMX6
sabre Lite board). We can also debug the applications on board,
but we can not debug on desktop.
When /usr/bin/gdb is started it starts automatically
/usr/bin/python. It fails because Ubuntu python does not recognize
sys.lib variable from /op/poky...python. We have found no way to
tell gdb to start changing PYTHONHOME to Ubuntu python home to
avoid the problem.
So we need to add gdb to the toolchain. If we get it to work, we
suppose the /op/poky...gdb will start the /opt/poky...python (we
test it and that python knows what sys.lib is).
We try to add to conf/local.conf: TOOLCHAIN_HOST_TASK_append = "
nativesdk-gdb". But nativesdk-gdb is not a defined name.
try adding packagegroup-cross-canadian-${TRANSLATED_TARGET_ARCH} in
TOOLCHAIN_HOST_TASK_append which will add cross toolchain to your sdk
which includes cross gdb as well. There is no nativesdk-gdb afaik
unless if someone says otherwise.
see ./recipes-core/packagegroups/packagegroup-cross-canadian.bb
<http://packagegroup-cross-canadian.bb> for details.
I am lost. We added that but it did not work as we expected. In fact, I
think that must be included in meta-toolchain-qt because we do not see
any differences. Perhaps I explained it badly.
I think we already have the cross tools compiled. They are installed at:
/opt/poky/1.4.2/sysroots/i686-pokysdk-linux/usr/bin/armv7a-vfp-neon-poky-linux-gnueabi
There is a arm-...-gdb there, but this is not the failing gdb.
We expect/want to have a gdb compiled for the host machine at
/opt/poky/1.4.2/sysroots/i686-pokysdk-linux/usr/bin/
QT Desktop mode is starting /usr/bin/gdb but using the /opt/poky...
directory as PYTHONHOME. We think if we have our
/opt/poky/../usr/bin/gdb and we tell QT to use it, it will avoid ths
sys.lib conflict.
Thanks and best regards
