How to use qmake to cross-compile for imx6?

[SGaist]

You are at least missing the sysroot option.

@SGaist Excuse fro the question, but sysroot what is??

[jsulm]

@Alexander-9 Sysroot is a directory containing the content of the target device file system (or parts of it). It must contain all needed header files and libraries from your target device, else you cannot cross-compile.

[Alexander-9]

@jsulm, @SGaist , this the new cross-compile: ./configure -release -opengl es2 -device linux-imx6-g++ -device-option CROSS_COMPILE=/opt/poky/2.0/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi- -sysroot /dev/sdd -opensource -confirm-license -prefix /opt/imx6, is correct this??

after of run the configure, show me in the Config.log:

executing config test verifyspec

• cd /home/qt/Descargas/qt5/qtbase/config.tests/common/verifyspec && /home/qt/Descargas/qt5/qtbase/bin/qmake -qtconf /home/qt/Descargas/qt5/qtbase/bin/qt.conf "CONFIG -= qt debug_and_release app_bundle lib_bundle" "CONFIG += shared console" "QMAKE_CFLAGS += --sysroot=/dev/sdd" "QMAKE_CXXFLAGS += --sysroot=/dev/sdd" "QMAKE_LFLAGS += --sysroot=/dev/sdd" /home/qt/Descargas/qt5/qtbase/config.tests/common/verifyspec

I have that install more packges??

/dev/sdd ? Highly unlikely since it represent a drive on your system not even a partition but the whole physical drive.

You need to pass the folder where you copied your device file system.

[Alexander-9]

@SGaist @jsulm I already add the sysroot ./configure -release -opengl es2 -device linux-imx6-g++ -device-option CROSS_COMPILE=/opt/poky/2.0/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi- -sysroot /media/qt/rootfs/ -prefix /usr/local/qt5, the sysroot contain the folders: bin, build, boot, etc, is correct??

Generates me this error of compilation: Config.log.

[SGaist]

Did you do it from a clean state ?

[Alexander-9]

@SGaist I have executed the command make clean, is correct or i have run other command??

[SGaist]

Well, the best thing to do is an out of source build, so if something goes wrong you just nuke the folder and start anew. This has also the advantage to leave the sources untouched.

[Alexander-9]

Because also delete of folder qt-everywhere-opensource-src-5.8.0 and again extract qt-everywhere-opensource-src-5.8.0.zip for run the ./configure

[SGaist]

Avoiding to delete and decompression of the source each time will be a gain of time.

[Alexander-9]

So what you recommend me to do??

[SGaist]

I already wrote it: use out of source builds.
