Has anyone successfully built Qt from source recently on a Pi?

[ambershark]

@andrewg Just so you don't go unanswered again.. :)

I have built Qt by source a LOT on osx, linux and windows but not on an embedded device like a Pi.

I'd be happy to help you resolve some errors if I can.

What are the problems you are running into during the build?

[nestorac]

This also interests me, as I am planning to develop for raspberry pi.

[andrewg]

Thanks @ambershark!
Up to now I've been working on building Qt5.7.1. If you're willing to help me through the build process I'm going to try this with 5.8.0 instead. My feeling is that each combination of Qt + Raspbian + Pi is going to require it's own set of patches, so let's just work with the latest and greatest for now :)

I'll set up a build tonight and see if there is any low hanging fruit that I can resolve before putting questions to you.

[ambershark]

@andrewg Sure just post here with whatever issues you run into. Make sure to give me some idea of what you've done already, i.e. your ./configure line and whatever else you change/feel is important. :)

[nestorac]

I think raspbian comes with qt, not by default, but you can install it easily.

[andrewg]

@nestorac - That's correct. apt-get has a package for Qt. I believe it is Qt 5.3. For my application I know that I'll need features that have been more recently introduced, but if you don't have those requirements the apt-get route will be much easier.

@ambershark - I made some good progress on this, but still came up short. To keep things simple I tried to stick to the following guide as close as possible: https://wiki.qt.io/Native_Build_of_Qt_5.4.1_on_a_Raspberry_Pi
I'm using the qt-everywhere-opensource-src-5.8.0 source package. I also skipped the whole part about building on a flash drive since I'm not in a time crunch. This means I'm doing everything on the local SD card and I didn't add the extra swap file, but I'm also only running a single thread for the make step (not using the -j3 argument).

On the first pass the build failed with the error "Project ERROR: Library 'libpng' is not defined." Some googling pointed me to this bug report which seems somewhat related: https://bugreports.qt.io/browse/QTBUG-57794. It seems like the issue is that the build process can't find my system libpng. I'm not too particular about where libpng comes from so I used the option to use Qt libpng. I started over with the same configure script and added the argument -qt-libpng at the end.

The second pass failed trying to link canbusutil. The error message is below. I'll need serial bus functionality for my application so I'm not as comfortable adding configure options to alter how it builds. Do you have any ideas as to why these references are incorrect? Let me know if you need any more information.

@andrewg Sorry haven't been around for a while, I've been very busy.

That looks like you are having issues with network stuff. Both in QtNetwork as well as QtSerialBus.

Check the Qt5SerialBus library to see if the symbols actually exist in there. You can do that with the nm command.

Another option is it is pulling in a bad version (i.e. your desktop version) of the Qt networking stuff. That seems less likely though.

My guess is those networking qt libs didn't build properly. Or the link line is lacking a library it needs. I'm not seeing it right off the top of my head though.

[gzotti]

I just came across the same issue. While compiling Qt5.8 from sources, the linker tries to link against the installed qt5.3.2 version. apt-get remove libqt5* solved it.

Hi,

I am trying to build QT from source to run on a RPi 3.

I tried to setup a cross compile tool chain but was unsuccessful because I had to first build a cross compile tool chain from source as I am on MacOS and I couldn't use the prebuild linaro gcc tool chains found at https://www.linaro.org/downloads/.

I tried to build my own tool chain using instructions and scripts found at
https://clxdev.wordpress.com/2016/06/20/building-linaro-toolchains-on-os-x/ but it was for older linaro releases.

I was going to download the linaro source from http://releases.linaro.org/components/toolchain/binaries/latest/ But I couldn't determine which one applied to the Raspberry Pi.

Jared Wolff created a precompiled toolchain for Raspberry Pi 3 on OsX Mavericks that is found at https://www.jaredwolff.com/toolchains/. I will give that a try soon.
See https://www.jaredwolff.com/blog/cross-compiling-on-mac-osx-for-raspberry-pi/

In the meantime I am trying to build QT from source right on the RPi 3 itself.

I tried to follow the instructions at https://wiki.qt.io/Native_Build_of_Qt5_on_a_Raspberry_Pi

My environment is

• QT 5.8.0 from http://download.qt.io/official_releases/qt/5.8/5.8.0/single/qt-everywhere-opensource-src-5.8.0.tar.gz
• Raspberry Pi 3
• Raspbian Jessie (2017-03-02)
• PiTouch screen

From folder ~/build-qt, my I executed

Platform notes:

            - Also available for Linux: linux-clang linux-kcc linux-icc linux-cxx
        

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into /opt/Qt5.8

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

I executed

make -j4 2>&1 | tee output_make.log

@msluser said in Has anyone successfully built Qt from source recently on a Pi?:

CROSS_COMPILE=/urs/bin/

That is probably an issue.. should be /usr/bin.

Also you normally want to start new threads and not necro an old one like this. :)

And finally, you cut the build log so it doesn't show any errors. If you should the actual errors I can try to help you more.

@ambershark

I made a mistake posting what I typed. I checked and I used
CROSS_COMPILE=/usr/bin/

There were no errors in the configure step.

I noticed this in the output of my make step:

[ambershark]

@msluser Ah, do you have the libxcb package installed for the PI? Trying search your PI filesystem for xinerama.h and see if it is installed. You may just need to point your compile at that include directory.

Or (and the more likely scenario), you don't have libxcb installed for the PI.

[msluser]

@ambershark
Thanks for the help!

I got past the xinerama.h error, but now I get

@msluser Lol scroll up... that problem was addressed in this thread already. ;)

@ambershark

Thank you for all of your help this far. As per your last recommendation, I executed

sudo apt-get uninstall libqt5*

I was able to get the "make" to run however the last thing it output was

I am not sure that "make" was successful. What do you think?

When I try and run

Obviously it didn't install correctly and there is an error. Is it because of my file /usr/include/stdc-predef.h or something else ?

I appreciate your help @ambershark , thank you very much.

[ambershark]

@msluser That error comes from using a dirty build from mixed Qt's. Since you cleaned up your Qt conflict (you didn't have to uninstall, but that works) you should now rebuild the entire Qt project.

I would start with a completely fresh extract of the qt tar so you know it's 100% clean. Sometimes make distclean doesn't get everything.

If you rebuild everything it should fix that pch on install. As for whether or not the build succeed that make output is definitely a success, the make install however failed.

And you're welcome. :)

I've also struggled a lot with compiling Qt natively on the RPi3. I've tried to compile the new Qt 5.8 in hopes that the fact that it now uses Gstreamer1.0 instead of 0.10 would fix issues I have with an application that uses QSound and QMediaPlayer, both part of the QtMultimedia library.
After a lot of trial and error and trailing forums, I have managed to successfully build Qt 5.8 from source.

My environment:

• Qt 5.8.1 from git://code.qt.io/qt/qt5.git
• Raspberry Pi 3
• Raspian version 8.0 Jessie
• Kernel: 4.4.50-v7+ #970 SMP Mon Feb 20 19:18:29 GMT 2017

I wrote a script that automates the process. If you run all its commands, it will install dependencies, clone the source of your choice, init the repo, build the source, install and then create a script that exports the necessarily globals, which is appended to startup scripts.
I've pasted the whole script below, where you can see the options used for configure and what dependencies I made sure to install:

Note that I omit initializing QtWebkit in the repo to save time compiling as I didn't need it. I also skip compiling three libraries which would cause errors and prevent the remaining libraries from being compiled:

• QtSerialbus
• QtWayland
• QtScript

The source is downloaded and placed in a subdirectory where the script is run from (it can be run from anywhere you like).
The script also writes the output of each process to a set of "<name>.out" files, most of which are placed in the source directory.
To run the commands in the script, simply call it followed by the commands you want. E.g. if you name the script "qtFromGit.sh":

$ <pathToScript>/qtFromGit.sh clone init conf build install exports

Edit:
Running the whole process on my Pi took right above 5 hours, using all 4 cores:

real    303m23.636s
user    1087m58.200s
sys     47m28.890s

Edit2: Grammar

Of course, I'm still having issues with sound in my application, but that's another story fit for a separate thread...

[vikramg]

@ambershark The "undefined reference" link error was root-caused to the conflict with existing Qt 5.3.2 on the build machine. That has been resolved by folks in this thread by removing the older version, but you suggested that that need not be done. Would you elaborate on that? How might one avoid the conflict without removing the older conflicting version? Thanks.

[ambershark]

@vikramg There are a few ways to do it easily. I'm only covering posix OSes though. I don't use windows enough to comment on how to do it there. I would imagine just making sure it isn't in your path would work in windows though.

1. Make sure you shell points to the Qt you want only. To accomplish this you will need something like:

$ export PATH="/path/to/Qt/bin:$PATH"
$ export QTDIR="/path/to/Qt"

I tend to add these to my .bashrc so they are always active in every shell I run. I have aliases for switching Qt versions.

To verify that your Qt is the one you want, run qmake --version. Then run qmake -query and verify the paths are pointing correctly. This should be handled by the QTDIR varaible. If not you will need a qt.conf file to force paths.

2. Another way is to disable the system Qt version. This of course will have undesired effects on any application that uses them on your system. The way I usually accomplish this is just setting permissions to 000 on the Qt include directory and libs/binaries individually if necessary. This way is a pain in the butt though. I recommend trying the above first and if you still have issues try this.

3. Finally, you could set up a vagrant/virtualbox build vm that doesn't include Qt as part of the distro. You could use a docker instance as well. This doesn't really hold true to my comment though but it is an option.

Hope that helps.
