Problems about Native build Qt5.7 on raspberry pi3
-
@jsulm
my device is rpi3,
should I use with -device linux-rasp-pi-g++ ?@JiujiuTong Try with -device linux-rasp-pi2-g++
See https://forum.qt.io/topic/68016/rpi3-device-missing/2 -
@JiujiuTong Try with -device linux-rasp-pi2-g++

well, actually i have tried both with linux-rasp-pi-g++ /linux-pi3-g++.
maybe i should try with linux-rasp-pi2-g++. life is so tough.....
thank you ! -

an interesting thing is that i following the steps:
http://wiki.qt.io/Native_Build_of_Qt5_on_a_Raspberry_Pi
it is ok now , the problem is that source code for git is same with the release code ?
can i use it for programming ? -

@jsulm
qt5.7
but the installation process is so quick, it only takes few minutes , so i don't think it is completed@JiujiuTong What do you mean by "installation process"? The "release code" is what you can find in the release branch in Git.

@jsulm
i mean the "make install" process,
it only takes more than two minutes
is the branch code same with the code download from qt (e.g. qt-everywhere-opensource-src-5.7.1.tar.gz)?@JiujiuTong "make install" shouldn't take long, "make" takes long

@JiujiuTong "make install" shouldn't take long, "make" takes long

@jsulm
the "make" process only take more than 2 minutes too, the configure process is very long about 7 hours ... no error information@JiujiuTong configure takes 7 hours? And make only 2 minutes?! You're doing something wrong. Are you sure make step was successful?

@jsulm
yes, many make output: nothing to be done for "first"
no error infors
the interesting thing is:
the configure output summary :
building on : linux-g++ (arm ,cpu features: none detected)
building for :devices/linux-rpi3-g++ (arm, cpu features: neon)
so i thing -device linux-rpi3-g++ option is correct,
the steps on http://wiki.qt.io/Native_Build_of_Qt_5.4.1_on_a_Raspberry_Pi
may have missing some critical steps or my ENV is not right -

i will double confirm it @jsulm -

i will double confirm it @jsulmI finish the installation with -skip webengine option,
then later, i want to install qt-creator 4.2, i need to run qmake -r , it promps that unknown module, in the README, it seems require webengine module.should i reinstall without -skip webengine ? or the best way should be cross compiler... @jsulm -

@jsulm
i finished the installation, how to know it is built successfully,
i have install qt-creator(qt5.3.2), i remove it and link the /usr/bin/qmake to the /usr/local/qt5/bin/qmake,
current qmake -v show the correct version info.
how to know the qt5.7 is correct installed on rp3? thank you ! -

You should not link /usr/bin/qmake to /usr/local/qt5/bin/qmake! In QtCreator you can add your Qt version selecting its qmake. -

@jsulm
i can not install qtcreator directly on rpi3@JiujiuTong You can build an app without qtcreator:
/usr/local/qt5/bin/qmake make -

ok it's installed properly,thank you !
