Problems about Native build Qt5.7 on raspberry pi3
-
@jsulm
yes you are right!
to be honest i don't know much about Qtwayland, if disabled , is there any other side-effects as EGL-X11 is disabled ?
thank you every much!@JiujiuTong If you don't want to use Wayland then there are no side effects if you don't build it. You need support for what ever graphics you want to use. Do you want to use X11?

@jsulm
thanks for your rapid reply!
i try to install the QT5.7 on rpi3 because i want to learn developing qt application on rpi3 with OS(RASPBIAN JESSIE WITH PIXEL), the main purpose is playing multimedia.
as i'm a fresher to linux, i don't know much about X11, from the internet information, it seems there is no need to have this feature for my usage, am I right ? -

So, if you want to test GUI applications you need X11. You most probably already have it as you're running Pixel. If Qt configure complains about OpenGL then you need to install OpenGL devel packages.

@jsulm
sorry, i don't understand.
do you mean i need to enable EGL-X11?
from the configure log it seems that "OpenGL ES 2.0 enabled".
what should i do then ?
thank you！@JiujiuTong then disable QtWayland and try again

@jsulm
OK, I will have a try! hope it works
thank you very much.
i will tell you the result later!@JiujiuTong add -skip wayland to your configure call
-
@JiujiuTong add -skip wayland to your configure call
@jsulm
got it ! -
@JiujiuTong add -skip wayland to your configure call
@jsulm
the problem is solved with -skip wayland option
but another problem happens:
the make install output error
/usr/bin/ld: cannot find -lclip2tri
/usr/bin/ld: cannot find -lpoly2tri
/usr/bin/ld: cannot find -lclipper
I know it means that three libs are not find, but there are tips above:

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

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

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.prlbut no lib files. it's strange...
do you have any other suggestions ? thankyou!@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 Makefilethen make and make install

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

@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 ?@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.
