Building on device with small root partition

dobey

@anhilde You will need to switch to devel channel to be able to test anything you build now, as we have merged Qt 5.12, and so you've built against that when compiling.

As for sudo inside the container, you should never use it and never install it inside libertine. It will not work and can break other things if installed.

doniks

@anhilde maybe you want make a PR to update the "on the device" section in the docs to use libertine. It probably makes more sense to suggest libertine first and then there can be some footnote, that depending on resources one can also attempt on the root partition ...

anhilde

@doniks Yes that makes sense, however I have not yet succeeded building within the container.

To be specific, the build went through, but at runtime there is a library missing (libGLES), which is also the case when running the tests (I commented them out). Note, I did switch to the Development channel. So while the build goes through and I can theoretically start the build result from outside the container, the app fails to run due to the dependecy problem.

My assumption was, since I tried all sorts of approaches in my explorative stage of app development with the container, that I messed something up. Therefore I gave it another go with a fresh container. However I get new troubles. My main problem, I think, that it is not clear to me how to get the container configured efficiently for a build of a specific component. In the documentation on how to build on the device on the root partition, there are these steps:

sudo apt update
sudo apt build-dep address-book-app

However if I do this, the packet installation always fails with the message, that the package installation requires root access:

@anhilde said in Building on device with small root partition:

However if I do this, the packet installation always fails with the message, that the package installation requires root access:

You need to enter the libertine container differently so that you are using it as "root" like so:

libertine-container-mainager exec -i <containerid> -c bash

This will give you a "root" prompt inside the container, and you should be able to use apt build-dep then (assuming you did not install sudo in the container).

After that, you can exit the "root" prompt, and run the standard container shell normally, to be able to build the packages.

anhilde

@dobey Thanks, that was the missing link to getting the container set up. However the tests still fail with the libGLESv2.so.2 issue, same as I had before when trying with the "manually" configured container:

doniks

@anhilde maybe you need to install more stuff

maybe libgles2-mesa-dev https://packages.ubuntu.com/search?suite=groovy&arch=any&mode=filename&searchon=contents&keywords=libGLESv2

anhilde

@doniks I would have though, that that should be taken care off by:

apt build-dep

Is that assumption wrong? Nore, I'm not trying to get this working somehow, but rather want to try and understand how the application development process is intended.

anhilde

Hi, I have a problem understanding, how the (if?) the build application should be runnable from within the container. When the build runs the tests I assume it uses the executable address-book-app found in the project tree.

Does anybody have a clue why then the tests fail with the message that libGLESv2.so.2 is missing? Note I do have dyslexia, so if there is an obvious name mix up here, please let me know.

dobey

@anhilde Well GLES2 is there. There does seem to be a weird issue though, since it's not finding the libs when using the container normally. Especially odd given that it compiled and only failed when trying to run the tests.

As for what is run for the tests, no, it is not running the address book app itself, but other tests binaries, or qmltestrunner for QML tests.

I would have assumed the same yes ...

Nore, I'm not trying to get this working somehow, but rather want to try and understand how the application development process is intended.

Understood. And very much appreciated! I was just thinking maybe there is a genuine bug in the dependencies.

Full disclosure, I've never done this on-device build myself. I'm just thinking out loud here.

Also, I just notice that there are two packages that have this lib: mesa and hybris. Maybe you actually need the other one. Or a related thought: Maybe you can run the tests from OUTSIDE the container, after the building INSIDE is complete.

dobey

@doniks said in Building on device with small root partition:

, after the building INSIDE is complete.

The build is incomplete, because the tests failed to run.

anhilde

@dobey I cannot get the build to run. I always end up with the libGLESv2.so.2 problem. I actually tried installing all packages via:

libertine-container-manager install-package -p $ALLPACKS_FROM_APT_BUILD_DEP_COMMAND

The very first build fails with:

phablet@ubuntu-phablet:~/address-book-app$ DEB_BUILD_OPTIONS="parallel=2 debug" dpkg-buildpackage -rfakeroot -b
dpkg-buildpackage: source package address-book-app
dpkg-buildpackage: source version 0.4~0ubports1
dpkg-buildpackage: source distribution xenial
dpkg-buildpackage: source changed by Alberto Mardegan <mardy@users.sourceforge.net>
dpkg-buildpackage: host architecture armhf

dpkg-buildpackage: warning: build dependencies/conflicts unsatisfied; aborting
dpkg-buildpackage: warning: (Use -d flag to override.)

I installed these packages as well with the libertine-container-manager. Following that the build works, until the test execution fails.

I fiddled with the LD_LIBRARY_PATH, just to see if I can get anything going and ran the qmltestrunner manually, leading to this output:

phablet@ubuntu-phablet:~/address-book-app$ export LD_LIBRARY_PATH="/usr/lib/arm-linux-gnueabihf:/usr/lib/arm-linux-gnueabihf/mesa-egl:$LD_LIBRARY_PATH"
phablet@ubuntu-phablet:~/address-book-app$ /usr/lib/arm-linux-gnueabihf/qt5/bin/qmltestrunner
qt.qpa.xcb: could not connect to display 
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

Aborted

At that point I am wondering, with entering the container with DISPLAY= , there won't be a display available ever in there. So can these tests really run in the container? Is there a nightly build that I could try to investigate, to see how this should be done?

well ok, but I would assume that the build process first creates executables and then tests them. so, if the executables exist, one could still try to use/test them outside the container.

and even if the failing tests are before some final step that puts the executables together maybe anhilde can relatively easily disable them for the moment, to get one step further

@anhilde

root@ubuntu-phablet:/# ldd /usr/lib/arm-linux-gnueabihf/libQt5Gui.so.5
	libGLESv2.so.2 => /usr/lib/arm-linux-gnueabihf/mesa-egl/libGLESv2.so.2 (0x00000000)

so this is the mesa version, maybe you need the hybris one https://packages.ubuntu.com/search?suite=xenial&arch=armhf&mode=filename&searchon=contents&keywords=libGLESv2 so I guess you could try to libertine-container-manager remove-package -p libgles2-mesa-dev and instead libertine-container-manager install-package -p libhybris

dobey

@doniks said in Building on device with small root partition:

so, if the executables exist, one could still try to use/test them outside the container.

I mean, the packages aren't built yet, because the tests failed, so it's not so easy to do things with them outside the container.

anhilde

@dobey I have pulled the *.deb files from the container and installed them with dpkg -i which results in the libGLESv2.so.2 missing error as well.

dobey

@anhilde Did you disable the tests or something? How did you get debs built to install if the issue wasn't resolved?
