Errors while configuring Qt5.5 for Beaglebone black
-
Hello Developers
Following your instructions on Internet I was trying to cross build Qt 5.5.1 on my ubuntu host machine and Beaglebone black as target.
As a summary I took following steps:
mount /dev/sdx1 /mnt/bbbhf
wget https://releases.linaro.org/14.11/components/toolchain/binaries/arm-linux-gnueabihf/gcc-linaro-4.9-2014.11-x86_64_arm-linux-gnueabihf.tar.xz
mkdir /opt/arm-toolchain
tar -C /opt/arm-toolchain -xvJf gcc-linaro-4.9-2014.11-x86_64_arm-linux-gnueabihf.tar.xz
cd cross-compile-tools
#./fixQualifiedLibraryPaths /mnt/bbbhf/ /opt/arm-toolchain/gcc-linaro-4.9-2014.11-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++
cd qt-everywhere-opensource-src-5.5.1
cp -r qtbase/mkspecs/devices/linux-beagleboard-g++ qtbase/mkspecs/devices/linux-bbbhf-g++
vi qtbase/mkspecs/devices/linux-bbbhf-g++/qmake.conf
And then I changed:
COMPILER_FLAGS = -march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp
to
COMPILER_FLAGS = -march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=hard
#./configure -opensource -confirm-license -no-pch -prefix /opt/qt551-bbbhf -release -force-debug-info -device linux-bbbhf-g++ -make libs -nomake tests -nomake examples -device-option CROSS_COMPILE=/opt/arm-toolchain/gcc-linaro-4.9-2014.11-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf- -sysroot /mnt/bbbhf -v -qt-zlib
After running configure command i got lot of errors as given in the end of mail, can you please tell me what can be possible reason for it.
Additionally please inform me if you need any information from me.
Thank you very much
