b2qt-embedded-qt5-image fails to build for intel-corei7-64

behnkjoc

Hello,
I am running the prebuilt „b2qt-embedded-qt5-image“ on an Intel Atom E3930. Now I want to build the same image myself from source using „bitbake b2qt-embedded-qt5-image“ . The build persistently fails when it comes to building the package „packagegroup-b2qt-embedded-tools“.

The stack trace of python calls that resulted in this exception/failure was:

I understand, that the pkgdata direcory is missing, but what is the cause?

Any suggestions what could be the problem?

I ran the bitbake process a second time, and now it succeeded.

I guess that some interruptions of the first build process somehow led to inconsistent build caches.
For example git-lfs was missing (but this was detected right at the beginning of the build process, so I don‘t think this was the culprit).

So I went through the b2qt build instructions once again.
But this time

I updated the required software packages using
$> sudo apt-get install gawk curl git-core diffstat unzip p7zip-full texinfo
gcc-multilib build-essential chrpath libsdl1.2-dev xterm gperf bison
g++-multilib
This resulted in some software packages being added and some existing being upgraded
I ran bitbake from a virtual console
I am running xubuntu 16.04 LTS and recently my desktop sessions sometime have been closed, when bitbake ran for a while. So I decided not to run bitbake from a GUI terminal, but from a virtual text console.
I created a new build environment from scratch
I created a new directory for the b2qt build environment and ran the b2qt-init-build-env script from there. So I was sure there was no old stuff laying around.

As already said, „$> bitbake b2qt-embedded-qt5-image“ then successfully built the image.
Problem solved.

Hi and welcome to devnet,

Boot2Qt being a licensed product, you should rather ask the Qt Company directly.

Thanks for your reply.
I am new to Qt and thought this forum is run by the Qt company.
I'll give Qt company support a try.

They handle the infrastructure but this is a user forum mostly answered by volunteers.
