How to use qmake to cross-compile for imx6?
Guest last edited by Guest
I work in Debian Jessie with a freescale imx6, i want to get qmake for make a cross-compile to imx6, i intented run this configuration link text, but i display this error:
collect2: error: ld returned 1 exit status
make: *** [../bin/qmake] Error 1
This image is of error:
Someone could help me, thanks.
The main problem is that you are trying to cross-compile Qt 5 with instructions for Qt 4.
What cross-compiler are you using ?
The tools that i use:
- Qt 5.8.0.
- Qt creator 4.2.1
- Poky linux 2.0.3.
Good to know, however that doesn't answer the question about the cross-compiler version.
For the cross-compiler i use toolchain the next : poky-glibc-x86_64-meta-toolchain-qt-armv5e-toolchain-qt-2.0.3.sh, i am in the correct??.
after of install some packages, i can run ./configure https://drive.google.com/file/d/0B66wEl1-cjbObjJEY1pYd3lkTU0/view?usp=sharing.
but in the moment that run make, show me the next error https://drive.google.com/file/d/0B66wEl1-cjbOOUQ4NzBkRDBORTg/view?usp=sharing.
or what is the error i am making??, regards
From what you wrote you try to use a toolchain that is for ARMv5, the imx6 AFAIK, runs on an ARMv7 so I'd say no that won't do it.
Also, please translate the error message.
@SGaist, Hi i can run ./configure and if create the qmake, but the qmake that create is for x64 and this is what i don't want, i have that add other thing else, for that can create a qmake for ARM.
@Alexander-9 You need to cross-compile for your target. You can see how it is done for Raspberry Pi here http://wiki.qt.io/RaspberryPi_Beginners_Guide (don't know what your target device is, but it will be similar).
To add to @jsulm, that's normal. When cross-compiling there are host tools like qmake that will be built for your desktop machine so your can develop on said machine while targeting your device.
If you want build your application directly on your target then you'll have to do a native Qt build on your target also.
./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- -opensource -confirm-license -prefix /opt/imx6, this way of cross-compile is correct??
But show me this ERROR: Cannot compile a minimal program. The toolchain or QMakeSpec is broken., and for details Config.log, in this moment i'm seraching the way for add the files crt1.o, crti.o etc, etc, regards.
You are at least missing the
@SGaist Excuse fro the question, but sysroot what is??
@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.
@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:

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.
@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.
Did you do it from a clean state ?
@SGaist I have executed the command make clean, is correct or i have run other command??
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.
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
Avoiding to delete and decompression of the source each time will be a gain of time.
So what you recommend me to do??
I already wrote it: use out of source builds.
