Beaglebone Cross compile setup

[Grkan]

Hello,

First of all, I want to mention I've never worked QT and Linux before. I'm quite new to this environment.

I've been trying to develop a simple application for Beaglebone Black.

After I've searched quite bit, I've seen there a lot of information on internet but most of them are out-ouf-date. I just need to some guidance to setup the environment if you anyone can help.

In last 3 days, I've learned that;
-Get an image for BBB (I've created with Debian 9.5 2018-10-07 4GB SD LXQT which has GCC 6.3.0)
-Download Linaro Arm Toolchain ( https://releases.linaro.org/components/toolchain/binaries/6.3-2017.05/arm-linux-gnueabihf/)
-Download QT (I've used binary file again from http://download.qt-project.org/official_releases/qt/5.9/5.9.0/)
First I've used the online installer (qt-unified-linux-x64-4.0.1-online.run). I was able to build a demo application for linux but I couldnt create a kit for Beaglebone Black. As I understood I need to compile from source code with ./configure to be able to create qmake for BBB.

I've tried to use this config

./configure -device linux-beagleboard-g++ -device-option CROSS_COMPILE=home/grkan/opt/gcc-linaro-6.3.1-2017.05-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf- -sysroot home/grkan/opt/arm-toolchain/sysroot-glibc-linaro-2.23-2017.05-arm-linux-gnueabihf -opensource -confirm-license -optimized-qmake -release -make libs -prefix /usr/local/qt5bbb -hostprefix /usr/local/qt5bbb -qt-zlib -qt-libpng -openssl -v

But I'm getting this output in log file

Command line: -device linux-beagleboard-g++ -device-option CROSS_COMPILE=home/grkan/opt/gcc-linaro-6.3.1-2017.05-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf- -sysroot home/grkan/opt/arm-toolchain/sysroot-glibc-linaro-2.23-2017.05-arm-linux-gnueabihf -opensource -confirm-license -optimized-qmake -release -make libs -prefix /usr/local/qt5bbb -hostprefix /usr/local/qt5bbb -qt-zlib -qt-libpng -openssl -v

I can confirm that home/grkan/opt/gcc-linaro-6.3.1-2017.05-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++ is existing.

I've tried installing qt5.15.2 (http://download.qt-project.org/official_releases/qt/5.15/5.15.2/single/)
With ./configure I'm getting following error and nothing in log file

Maybe you forgot to setup the environment?

Can someone please direct in a direction so I can build QT and start developing the application please?

Thank you.

@Grkan said in Beaglebone Cross compile setup:

CROSS_COMPILE=home/grk

You're missing a / here:

CROSS_COMPILE=/home/grk

[Grkan]

Thank you @jsulm, I've missed that part. It has been compiled and I'm available to deploy and debug right now.
