[Development] Qt5 Beta cross compiling problem

[Christoph Kurz]

Hi,

I have a problem cross compiling the Qt5-Beta for an i.MX6 Board.
The host OS is a Fedora Linux, the target OS is an embedded Linux.

Steps taken so far:

– I set up LTIB and created a rootfs for the target.

– I downloaded the Qt5 sourcecode and excluded svg and webkit by renaming the
corresponding folders

– I copied the linux-imx6-makespec in the qtbase/mkspecs folder (see attachment
"config.txt")

- I configured the build with the following command (runs without any errors):
./configure -prefix /home/local/CW01/uidv7014/Qt_for_target -developer-build
-confirm-license -opensource -nomake tests -nomake docs -nomake demos -nomake
examples -no-xcb -no-wayland -xplatform linux-imx6 -arch armv7 -opengl es2
-openvg -eglfs -release -v

- I tried to run make, but after a while, an error occurs (see attachment
"error.txt")



As this error seems to occur in the neon-package, I excluded it by using the
-no-neon option in the configure-command. This seems to work, but then a very
similar error occurs in the sqlite-package and in various other packages, too.

I compiled the Qt5 Alpha successfully, using the same specs and environment.

Any ideas?



- Chris
