Installation QT 5.11 on Raspberry Pi 3

gogoer

it gives

g++: internal compiler error: Segmentation fault (program cc1plus) 
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.9/README.Bugs> for instructions.

and after gives error i write upper.

Whoa, that I have not seen before. Perhaps try with some older Qt release, maybe it won't trigger the compiler error. Also, disable tests as it seems to happen in test lib (-nomake tests -nomake examples).

sierdzio

Also, as @sneubert suggests, cross compilation will allow you to build much, much faster.

That might be an out of memory error. I used to see that when I tried to build Qt in a VM that was not given enough memory.

maybe you can give link to manual, how crosscompile QT from windows? i have not linux machine now.
i found only manuals to crosscompile from linux.

You like making things harder for yourself, right? ;-) There is this guide but it's known to work for a very limited range of Qt versions only.

A much better option is to set up some Linux OS (in a virtual machine or as dual boot on your PC) and cross compile via Linux. It's really much easier to do (which does not mean it is easy...). Installing a Linux distro like Ubuntu takes 20 minutes.

ok, i'll make so))) if have problems (99%) i'll ask here or create new topic?

As you prefer, I don't mind.

I installed Ubuntu 18.04 in VirtualBox and now trying to install QT, following this:
http://doc.qt.io/QtForDeviceCreation/qtee-preparing-hardware-rasberrypi.html
I downloaded online installer, but i cant find QT for Device Creation. Only QT 5.11.2 and modules.
Can I install all i need via online installer?

gogoer

i compile QT in Ubuntu and have error:

what can i do?

More than likely you ran out of memory. That's when I see internal compiler errors. You can make g++ use less memory by not using -pipe which will write intermediate stuff to disk rather than piping it to the next process.

Like others have said you're much better off cross compiling on a good system, but if you want to continue you just need to lower g++'s memory consumption. The easiest way to do that is not allowing piping.

Edit: I replied before I saw @mranger90's post... he's absolutely right, that's exactly what popped into my head too. ;)

Definitely get at least a linux vm... using windows for anything other than playing video games is so 1990s ;)

Windows lost the OS wars about a decade ago and is very far behind posix OSes now.

what can i do?

These errors are because of your sysroot. They come from not having glibc (or whatever libc you use) in the target architecture. Those should be in your sysroot directory.

What is in /opt/qt5pi/sysroot? Is that a valid directory? What's the output of find /opt/qt5pi/sysroot ?

gogoer

i correct sysroot problem, thank you.

i deleted folders except listed upper.

then i configure with:

../qt-everywhere-src-5.11.2/configure -opengl es2 -device linux-rasp-pi3-g++ -device-option CROSS_COMPILE=arm-linux-gnueabihf- -sysroot /opt/qt5pi/sysroot -prefix /usr/local/qt5pi -opensource -confirm-license -skip qtscript -nomake examples -nomake tests -make libs -pkg-config -no-use-gold-linker -v

and its configured without errors, just some notes.

during compilation have errors:

what it can be?

Oh, I remember stumbling upon that error myself, but I don't remember how I resolved it myself (possibly by switching OpenGL driver in pi-config and updating sysroot).

These might help:

gogoer

thank your all!!! i compiled and builed qt 5.10.1. I tryed build 5.11.2, but have errors. I think 5.10.1 is enough.
I installed QTCreator and configured it. But when i compile project, i have error:

sys/cdefs.h: no such file or directory

file cdefs.h is in /usr/include/sys/cdefs.h, ichecked it.
i do:

export Path=$PATH:/usr/include

but i have same error still building project in QTCreator.
what i need to do to solve this?

sierdzio

Have you followed the guide for setting up Qt Creator for use with RPi? https://wiki.qt.io/RaspberryPi2EGLFS#Qt_Creator

gogoer

yes i do.
but at Kit screen i have error: compiler "RaspGCC" (x86-linux-generic-elf-64bit) cant create code for QT profile "Q5.10.1 (qt5pi)" (arm-linux-generic-elf-32bit).

Hm, unless you misconfigured the RaspGCC compiler (see in "compilers" tab), it should work. If you're using Qt creator 4.7, try with 4.6. I've seen similar issues on Android with newest QtC, perhaps it's just IDE bug.

i configured everythin by manual one more time, now when i create empty qtquick project in qtcreator and try to build it, i have in console output:

cannot run target compiler 'arm-linux-gnueabihf-g++'
