Native Build of Qt on Raspberry Pi-3

swathi

Hi All,

I build Qt 5.9.2 on Raspberry Pi3 board. I refered the below link.

https://wiki.qt.io/Native_Build_of_Qt_5.4.1_on_a_Raspberry_Pi

but I am getting error after giving below command.

./configure -v -opengl es2 -tslib -force-pkg-config -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=/usr/bin/
-opensource -confirm-license -optimized-qmake -reduce-exports -release -qt-pcre -make libs
-prefix /usr/local/qt5 2>&1 | tee config.out

Note: Disabling X11 Accessibility Bridge: D-Bus or AT-SPI is missing.

You might need to modify the include and library search paths by editing QMAKE_INCDIR_OPENGL[_ES2],
QMAKE_LIBDIR_OPENGL[_ES2] and QMAKE_LIBS_OPENGL[_ES2] in the mkspec for your platform.

How to solve this above errors?

Could you please provide detail information on qt5 build procedure.

Thanks and Regards,
Swathi.

Hi and welcome to devnet,

First of all, do out of source builds so you can more easily start from scratch if you have an error.

You should add the -v option to your configure parameter so it shows exactly what's going wrong.

swathi

Could you please give the ./configure command.

@swathi I'm using this command to crossCompile

./configure -release -opengl es2 -device linux-rasp-pi3-g++ -device-option CROSS_COMPILE=~/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf- -sysroot ~/raspi/sysroot -opensource -confirm-license -make libs -prefix /usr/local/qt5pi -extprefix ~/raspi/qt5pi -hostprefix ~/raspi/qt5 -v -no-use-gold-linker

but it seems that you are missing some development files....please give more debug info

SGaist

Where is your source located ?

Again, do out of source builds, if you are calling configure again and again in the sources without doing a cleanup you are going to have all kinds of troubles.

Also, you should parse the output to see what makes the OpenGL test fail.

Hi,

I followed "https://wiki.qt.io/Native_Build_of_Qt_5.4.1_on_a_Raspberry_Pi" Link but I downloaded the link source file qt_5_9_1.

I modified the configure line like this.( linux-rasp-pi-g++ repalce with linux-rasp-pi3-g++ )

./configure -v -opengl es2 -tslib -force-pkg-config -device linux-rasp-pi3-g++ -device-option CROSS_COMPILE=/usr/bin/ -opensource -confirm-license -optimized-qmake -reduce-exports -release -qt-pcre -make libs -prefix /usr/local/qt5 2>&1 | tee config.out
I am getting error.Could you please suggest the configure path.

I am using Raspberry Pi3 board with "2017-09-07-raspbian-stretch" image. SD card size is 32 GB and I mount the Pen drive for building qt. Pen drive size is 16gb.

How much space is required for building and what size of SD card and pen drive is required.

Thanks in advance.
Regards,
Swathi.

Hi,

Yes I called configure again and again in the sources without doing cleanup.
How to cleanup the configure(Command for cleanup)?

Kart

ERROR: Feature 'pkg-config' was enabled, but the pre-condition 'tests.pkg-config' failed.

I believe if you provide sysroot to the configure, this error can be solved. The sysroot should have .pc files for the dependencies required.

The other errors are obvious. You are not having cross compiled opengl libraries. Mesa can provide you with these libraries. I am also having trouble cross compiling Mesa.

SGaist

make confclean

But as I already suggested, do out of source builds and nuke the build folder as needed.
