Full output on building meta-toolchain-qte

I tried to build the meta-toolchain-qte (Qt Embedded) on the dora branch. I want to use it for compiling qte apps with directfb instead of X11 for the i.MX6q

The following error occurs on building (host: Ubuntu 12.04):

| In file included from <command-line>:0:0:
| /home/udcu/fsl-community-bsp/build/tmp/sysroots/i686-nativesdk-pokysdk-linux/opt/poky/1.5/sysroots/i686-pokysdk-linux/usr/include/stdc-predef.h:39:1: error: one or more PCH files were found, but they were invalid
|  #endif
|  ^

Full log attached!

I found the problem: after removing the whole build/tmp directory everything compiled without problems.

I think the problem came from compiling the meta-toolchain-qt and direct afterwards the meta-toolchain-qte... maybe then some stuff isn't compatible.

Maybe this hint helps to get a workaround for this problem?

Hi Florian,

I tried to reproduce your issue but I couldn't. I used the dora branch and did two successive meta-toolchain-qt and meta-toolchain-qte builds for qemuarm. Build finished successfully. I'm closing this... If you succeed to reproduce it again, reopen it and fill in some clear steps to reproduce it myself.
