Problems about Native build Qt5.7 on raspberry pi3

[jsulm]

@JiujiuTong I don't know why those libs are not installed, but you can try to copy them manually

[JiujiuTong]

@jsulm
where can i find these libs? it seems that there are no libs created.....

[jsulm]

@JiujiuTong They actually should be built:

cd poly2tri/ && ( test -e Makefile || /home/pi/opt/qt-everywhere-opensource-src-5.7.1/qtbase/bin/qmake /home/pi/opt/qt-everywhere-opensource-src-5.7.1/qtlocation/src/3rdparty/poly2tri/poly2tri.pro -qtconf /home/pi/opt/qt-everywhere-opensource-src-5.7.1/qtbase/bin/qt.conf -o Makefile

[JiujiuTong]

@jsulm
OK, I will double confirm it.
after copy them manually, i would reinstalll again. thanks a lot!

@jsulm
i checked the files , there are three files:
libclip2tri.prl
libclipper.prl
libpoly2tri.prl

but no lib files. it's strange...
do you have any other suggestions ? thankyou!

[jsulm]

@JiujiuTong You can try to build those libraries manually:

cd poly2tri
/home/pi/opt/qt-everywhere-opensource-src-5.7.1/qtbase/bin/qmake /home/pi/opt/qt-everywhere-opensource-src-5.7.1/qtlocation/src/3rdparty/poly2tri/poly2tri.pro -qtconf /home/pi/opt/qt-everywhere-opensource-src-5.7.1/qtbase/bin/qt.conf -o Makefile

then make and make install

[JiujiuTong]

@jsulm
yes , i have create the libs,thank you !!

[JiujiuTong]

@jsulm
after i've create the archives(libclip2tri.a, libclipper.a,libpoly2tri.a ) ,then copy them to /usr/lib
and restart the QT configuer and make then make install, is it right ?

[jsulm]

@JiujiuTong *.a are static libraries, those are usually not in /usr/lib as they are only needed during linking, but you can try.
Actually you should copy them to the directory where you want to install your Qt.

[JiujiuTong]

@jsulm
thank you!
this problem solved, but another issue happened:

I am frustrated..i am following the steps :

why so many problems ? do you have any good ideas ? thank you !

@JiujiuTong In the description how to build Qt for RPi they use this for device: -device linux-rasp-pi-g++
You use -device linux-pi3-g++.
-march=armv8-a -mtune=cortex-a53 - this does not look correct for RPi.
Please try with -device linux-rasp-pi-g++

[JiujiuTong]

@jsulm
my device is rpi3,
should I use with -device linux-rasp-pi-g++ ?

[jsulm]

@JiujiuTong Try with -device linux-rasp-pi2-g++
See https://forum.qt.io/topic/68016/rpi3-device-missing/2

[JiujiuTong]

@jsulm
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 !

[JiujiuTong]

@jsulm
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]

@JiujiuTong It depends which branch/tag from Git you use. For each release there is a branch.

[JiujiuTong]

@jsulm
qt5.7
but the installation process is so quick, it only takes few minutes , so i don't think it is completed
