[oe] [meta-qt5][PATCH 0/2] Add nativesdk tools for Qt5 SDK

[Dominik Holland]

Hi all,

i'm the author of the merge-request on github.

The patchset from Denys looks nice. Especially because it cross compiles 
the host tools for the SDK_MACHINE which i forgot todo in my patchset.

I think the best way would be a combined version of both patchsets.

Because some of you think my patchset is too complicated i want to 
highlight why i added the complicated creation of the qt.conf and the 
additional patching of the mkspec files etc.

I didn't tested Denys version but i think it only works if you source 
the environment scripts of the SDK before.

As a Qt developer it's the defacto standard to get a SDK which works out 
of the box for your projects by just invoking qmake and no need to 
source a script before which changes your environment.

To get this done you need to patch the mkspec folder and the qt.conf to 
use relative paths instead the hardcoded paths which where created 
during the yocto build.

In addition i created a linux-oe-sdk-g++ which contains the real values 
of the environment variables but without --sysroot. This will be set by 
qt itself by using the CROSS_COMPILE prefix.


I hope you understand that this is really needed if you want to get a 
good qt5 integration into a OE SDK.

Best Reagrds

P.S. If you want to use the qmake inside qtcreator you would need to set 
all the env variable of the environment script inside qtcreator which is 
really inconvenient
