A few questions about cross-compiling on Rapberry pi
-
The guide proposes to clone Qt using git that's why there's no mention of a Qt archive
-
Thanks for replies.
I started working yesterday but I did not succeed to cross compile. I get error while performing qmake step on qtimageformat. Qtbase was not creat a problem and qmake works here well. All of the library gave following error witohut qtbase./home/sefa/opt/qt5/qtimageformats/.qmake.conf:1: Cannot find feature qt_build_config
Could not find qmake configuration file devices/linux-rasp-pi-g++.
Error processing project file: ./qtimageformats.proHow can I fix it?
-
How are you calling qmake ?
-
as /mnt/rasp-pi-rootfs/usr/local/qt5pi/bin/qmake.
-
IIRC, you should also have one on your computer in /usr/local/qt5pi, use that one
-
Thanks. This solved my problem. .I approached the end and I have another problem now I'm glad if you help some more. I made all the adjustments on qt creator. when I was run the app I get the following error;
:-1: error: Compiler /home/sefa/rsp/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-g++ not found. Check the value of CROSS_COMPILE -device-option
-
As silly as it may sound, is the file there ?
-
No such directory as /home/sefa/rsp.... This is my previous trying. Although I show the directory for the compiler as /home/sefa/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-g++. I get error that /home/sefa/rsp/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-g++ not found. Check the value of CROSS_COMPILE -device-option.
I do not understand why there is such.
-
You moved it after having compiled Qt ?
-
Ok I solved this issue by mkdir /home/sefa/rsp.. and copy past the compiler here. What about Unknown module(s) in QT: quick. This problem probably stems from this, at the end of the document said, go to the “Rasperry Pi” kit tab->System Environment and add LD_LIBRARY_PATH which is set to /usr/local/qt5pi/lib. But I do not know how to do it?
-
Before modifying anything, did you compile/install that module ?
-
I have a qtquick1 file. And I run the following string in this file.
/usr/local/qt5pi/bin/qmake .
make -j 4
sudo make install -
You need to build the qtdeclarative module. qtquick1 is for the version of 1
-
When I compiled qtdeclarative I get the following error.
make[2]: Entering directory
/home/sefa/opt/qt5/qtdeclarative/src/qmldevtools' make[2]: *** No rule to make target
/mnt/rasp-pi-rootfs/usr/local/qt5pi/include/QtCore/qglobal.h', needed by.obj/qqmljsast.o'. Stop. make[2]: Leaving directory

make[1]: *** [sub-qmldevtools-make_first-ordered] Error 2
make[1]: Leaving directory `/home/sefa/opt/qt5/qtdeclarative/src'
make: *** [sub-src-make_first] Error 2 -
Did you mount your Raspberry Pi root filesystem before building ?
-
Yes I did. Also I get another error when make app without using qtquick as;
error: error trying to exec 'cc1plus': execvp: No such file or directory
-
SGasist, Is there something you think about this issue ?
-
Did you move anything around like your compiler folder ?
-
No I did not move anything.
-
Then clean the module and call qmake again with your Rasberry Pie root filesystem mounted
