Qt 5.8 Cross Compile by arm-none-linux-gnueabi faild?

Question

I downloaded arm-none-linux-gnueabi from CodeSourcery version 2011, after set path and config with this command

sudo ./configure \ -opengl es2 -no-xcb\ -release -silent \ -continue \ -opensource -confirm-license \ -prefix $DEVICE_PREFIX \ -hostprefix $HOST_PREFIX \ -sysroot $SYSTEM_ROOT \ -device $TARGET_DEVICE \ -device-option CROSS_COMPILE=${CC} \ -qt-libpng \ -qt-libjpeg \ -nomake examples \ -nomake tests

Get this Error :

Answer 1

Your compilation log shows that it was trying to use the gold linker, however the command was not found. The later error of missing libraries and object files presumably stem from this error.

gold is a relatively recent addition to the GNU toolchain, and you're using a fairly old version (gcc 4.6.1) so I would suggest upgrading your toolchain to the most recent one, unless you have really good reasons not to do so.

Answer 2

Qt is quite opinionated when it comes to toolchain selection. There's a list of supported compilers which does not include something based on GCC 4.6. Given that Qt requires C++11 support these days, your chances of getting this working with an ancient compiler are severely limited.

Linaro provides nice toolchains for download. Is there any reason why you are not using one? Alternatively, you also likely require some additional SW on your BBB, so chances are that you're using a distribution like Debian or a building tool such as Buildroot or Yocto for producing your images. BeagleBone Black is a mainstream platform with support provided by essentially anything targetting embedded platforms.

A TL;DR version: Update your toolchain or your build environment. Qt is no simple library.
