Hi,
thank you for your help.
I am using the linux-arm-gnueabi-g++ mkspecs now.

Yes I created it and copied it from
http://imxcommunity.org/group/imxqt/forum/topics/building-qt-for-imx5x
That's how my new mkspecs looks like:
#
# qmake configuration for building with arm-linux-gnueabi-g++
#
MAKEFILE_GENERATOR = UNIX
TARGET_PLATFORM = unix
TEMPLATE = app
CONFIG += qt warn_on release incremental link_prl
gdb_dwarf_index
QT += core gui
QMAKE_INCREMENTAL_STYLE = sublib
include(../common/linux.conf)
include(../common/gcc-base-unix.conf)
include(../common/g++-unix.conf)
# modifications to g++.conf
QMAKE_CC =

QMAKE_CXX =
/opt/freescale/usr/local/gcc-4.4.4-glibc-2.11.1-multilib-1.0/arm-fsl-linux-gnueabi/bin/arm-none-linux-gnueabi-g++

QMAKE_LIBS_OPENGL_ES2 = -lGLESv2
QMAKE_LIBS_EGL = -lEGL
QMAKE_LIBS_THREAD = -lpthread
load(qt_config)
The new error I am getting is
bi/bin/ld: cannot find -lgsl
It's about the gstreamer. Is it possible to turn it off in the configure
command?
-no-multimedia doesn't work.

You should be able to ignore this error. The problem is that the configure
script makes qmake parse all .pro files, even those that are not used.

The -arch argument is no longer necessary. And the linux-g++-mx5x mkspec
is
not present, is this something you created?

Yes, it seems too long...
You could try first including ../linux-g++/qmake.conf and changing only
what
you need. This is my old mkspec for compiling for MeeGo ARM:
include(../linux-g++/qmake.conf)
QMAKE_CC = armv7hl-meego-linux-gnueabi-gcc
QMAKE_LINK_C = armv7hl-meego-linux-gnueabi-gcc
QMAKE_LNK_C_SHLIB = armv7hl-meego-linux-gnueabi-gcc
QMAKE_CFLAGS += -march=armv7-a -mfpu=neon -Wno-psabi
QMAKE_CFLAGS_RELEASE = -O3 -g
QMAKE_CXX = armv7hl-meego-linux-gnueabi-g++
QMAKE_LINK = armv7hl-meego-linux-gnueabi-g++
QMAKE_LINK_SHLIB = armv7hl-meego-linux-gnueabi-g++
QMAKE_CXXFLAGS += $$QMAKE_CFLAGS
QMAKE_CXXFLAGS_RELEASE = $$QMAKE_CFLAGS_RELEASE
QMAKE_LFLAGS += $$QMAKE_CXXFLAGS
QMAKE_LFLAGS_RELEASE += $$QMAKE_CXXFLAGS_RELEASE
QMAKE_AR = armv7hl-meego-linux-gnueabi-ar cqs
QMAKE_OBJCOPY = armv7hl-meego-linux-gnueabi-objcopy
QMAKE_RANLIB = armv7hl-meego-linux-gnueabi-ranlib
The qplatformdefs.h is just #include "../linux-g++/qplatformdefs.h".
