Problems about Native build Qt5.7 on raspberry pi3

[jsulm]

@JiujiuTong Per default Raspbian is using X11. 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.

[JiujiuTong]

@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！

[jsulm]

@JiujiuTong then disable QtWayland and try again

[JiujiuTong]

@jsulm
OK, I will have a try! hope it works
thank you very much.
i will tell you the result later!

[jsulm]

@JiujiuTong add -skip wayland to your configure call

[JiujiuTong]

@jsulm
got it !

[JiujiuTong]

@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:
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 ) && make -f Makefile install

it seams that the install process skip producing the libs,but later it need the libs, can you give any suggestions? thank you !

[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!

[JiujiuTong]

This post is deleted!

[JiujiuTong]

@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]

This post is deleted!

[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!

I am frustrated..i am following the steps :
http://wiki.qt.io/Native_Build_of_Qt_5.4.1_on_a_Raspberry_Pi
why so many problems ? do you have any good ideas ? thank you !

[JiujiuTong]

@jsulm
thank you!
