A suitable version of nss could not be found. Cross Compile Raspberry pi3 Qt5.10.1

[larime]

Hallo,

Hi,

I have a problem compiling qt 5.10.1 webengine module.
i configure with
../qt-everywhere-src-5.10.1/configure -release -opengl es2 -silent -device linux-rasp-pi-g'' -device-option CROSS_COMPILE=~/raspi/tools/arm-bcm2708/gcc-linaro-7.3.1-2018.05-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf- -sysroot ~/raspi/sysroot -opensource -confirm-license -make libs -prefix /usr/local/qt5pi -extprefix ~/raspi/qt5pi -hostprefix ~/raspi/qt5 -v -nomake examples -nomake tests -no-use-gold-linker -skip wayland -no-webengine-v8-snapshot -skip multimedia -D__ARM_ARCH_7M__ && make

The rest seems to be fine but when i want to build qtWebengine

~/raspi/qt5/bin/qmake -r
A suitable version of nss could not be found.
QtWebEngine will not be built.

Ubuntu environment 16.04
Please can someone help me.

Thank you

@larime Did you install libnss and libnss-dev?

hi,
@jsulm yes i do i have the last version on my Ubuntu

any idea please.

@larime You need that library for your device (in your sysroot) if you're cross compiling not for your host computer

[larime]

@jsulm i have already the last version on libnss in my sysroot/lib/arm-linux-gnueabihf/lib directory.

i have the same errors when i try to build Qtwebengine

thanks

[larime]

hello @jsulm

any idea please. what happens here?

Thanks

[jsulm]

@larime What about the header files of that lib?

[SGaist]

Hi,

From the looks of it, you didn't install the development package of nss on your sysroot.

[mewster]

if you are following the https://wiki.qt.io/RaspberryPi2EGLFS tutorial, sudo apt-get install libnss3-dev on pi3, then rsync and rerun the python script.

[larime]

@jsulm

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/home/vermop/raspi/qt5pi'.

can you see somthing wrong right her? i have nss config to no

Thanks

[SGaist]

You should check the build log to find out what is happening with nss.

Hello,

i reconfigure Qt for the build process and i see the nss is enable and everything look fine right now but i have a new error when the build process is going to build QtWebengine.

i think i have the right prozessor for the rpi3.

i configure with this command ? " ~/raspi/qt5/bin/qmake -r QM ~/raspi/qt5/bin/qmake -r QMAKE_CFLAGS=-march=armv7-a " but don´t work

Please do you have some ideas?

Thank you

[SGaist]

If you don't need QtWebEngine, then just avoid building it and go on with your project.

Out of curiosity, why not build Qt 5.12 since it's the latest LTS ?

[larime]

HAllo @SGaist

i need QtWebEngine for my Project.

i make some change in my QtWebengine directories config

i configure like this ~/raspi/qt-everywhere-src-5.10.1/qtwebengine$ ~/raspi/qt5/bin/qmake -r QMAKE_CFLAGS="-march=armv8-a -mtune=cortex-a53"

evrything work fine But the build unfortunately still fails with the error when linking libQt5WebEngineCore.so.5.10.1.

Hello @SGaist @jsulm

Thank you very much for your Help and support.

i be finally able to build very fine to Cross Compile Qt5.10.1 with QtWebengine on my Raspberry pi3 Model B.

The Thread of @SGaist has been very helpful

i solve my problem with the linked dependencies like @Lurch mentioned on the Thread please see below and i build Qt with success.

"The compact explanation: gl_ozone_egl.cc uses class gl::GLSurfaceEGL declared in gl_surface_egl.h, but the corresponding gl_surface_egl.cc is never compiled or linked into libgl_wrapper.a which goes into libQt5WebEngineCore.so.5.10.0 and thus the linker fails.

This can be shown by editing the two methods GLOzoneEGL::InitializeGLOneOffPlatform() and GLOzoneEGL::ShutdownGL() defined in in qt-everywhere-src-5.10.0/qtwebengine/src/3rdparty/chromium/ui/ozone/common/gl_ozone_egl.cc.

Open the file in your editor and comment out the uses of gl::GLSurfaceEGL::InitializeOneOff() and gl::GLSurfaceEGL::ShutdownOneOff(). Just return false in InitializeGLOneOffPlatform() for the whole function.."

Thank you very much Guys

Hello,

but i think it´s not very cool because i only able to build because i use the configuration

~/raspi/qt5/bin/qmake -r QMAKE_CFLAGS="-march=armv8-a -mtune=cortex-a53"

and i run my application and i have the first error.

glGetError 0x506
[6069:6105:0228/124507.705219:ERROR:gles2_cmd_decoder.cc(2523)] [.RenderWorker-0x15bcb0]GL ERROR :GL_INVALID_FRAMEBUFFER_OPERATION : GLES2DecoderImpl::DoBindTexImage2DCHROMIUM: <- error from previous GL command

may be it´s because i use "-march=armv8-a -mtune=cortex-a53" ?

Thanks
