Sorry for top-posting, but I wanted to reply in general and couldn't find the right place for inlining...
Anyway, the below assumptions aren't exactly correct. And the main one being - you don't really need to source the environment-setup script. But you'd need a different and much simpler qt.conf, which I populate as part of the meta-toolchain recipe (still pending submission though). And you can use relative paths in that generated qt.conf so qmake can be used w/o sourcing the environment-setup script. But even with absolute paths those will be fixed automatically by the SDK setup script at the install time... The thing is, you cannot re-use the same qt.conf that you generate for the nativesdk tools, because that one is for cross-compiling for SDK. Like you mentioned, it cross-compiles the tools for SDK_MACHINE, which is different from target MACHINE as well as the build host. When the tools are used, you need a different qt.conf with a makespec to run on SDK_MACHINE and build for target MACHINE. Also, I wanted the things to be as simple as possible, so I decided to re-use linux-oe-g++ makespec, as it is already there and we've been using it successfully for a long time with Qt4. The only thing is, existing linux-oe-g++ relies on the OE-specific variables, because that was the way OE SDK always worked. -- Denys On Mon, Dec 02, 2013 at 01:10:56PM +0100, Dominik Holland wrote: > Hi all, > > i'm the author of the merge-request on github. > > The patchset from Denys looks nice.
