Hi Konstantin,

I think I had this same problem awhile back.  Here are some notes from my custom qmake.conf file which I developed a long time ago for aArm cross-compile:

# In older toolchains, -march=armv7-a conflicts with -mcpu=cortex-a8.
# Use either
# -mcpu=cortex-a8
# OR
# -march=armv7-a -mtune=cortex-a8
# See https://bugs.launchpad.net/gcc-linaro/+bug/662720

QMAKE_CFLAGS_RELEASE    = -O2 -mfloat-abi=softfp -mfpu=neon -mcpu=cortex-a8


So, I think you should simply try using:

-mcpu=cortex-a8

instead of

-march=armv7-a -mtune=cortex-a8


Then I think your configure may succeed.

Greetings!

I'm using Qt on embedded arm platform. I have working configuration for building Qt-5.2.1:

So I'm wondering, what should I need to change in configuration to cross-compile Qt 5.3.x and higher...

Best regards,
