Having trouble with Cross Compile of Qt 5.5.0 build for ARM

samapollo

Hello,
I have been working at this for a couple of weeks now, and have not been able to build my version of Qt. I always run into the same error when I run my Make:

qlibrary_unix.cpp:(.text+0x1330): warning: Using 'dlopen' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking

This is my configuration:
./configure -shared -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=/home/sam/Qt5/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf- -sysroot /mnt/RaspImg/img2 -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -prefix /usr/local/qt5pi -hostprefix /usr/local/qt5pi -qreal double -qt-xcb -Wno-psabi

And this is my qmake.conf:

MAKEFILE_GENERATOR = UNIX
CONFIG += incremental
QMAKE_INCREMENTAL_STYLE = sublib

PLEASE HELP!!!

@samapollo I'm wondering why you try to link against static version of libdl: /mnt/RaspImg/img2/usr/lib/arm-linux-gnueabihf/libdl.a?
Don't you have a shared libdl.so?
