@jezek good idea actually, I will give that a try.

@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 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: 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?

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.

Since that is not directly linked to libGLESv2.so.2 my assumption was that this dependency comes in via libQTGui.so.5. Why is this not found?

If I search for it logged into the container as root I find libQt5Gui.so.5:

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.

@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.

@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 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:

@dobey I must have messed up something in the repo clone by earlier attempts to get something to build. I reset it then build again inside the container using:

DEB_BUILD_OPTIONS="parallel=2 debug" dpkg-buildpackage -rfakeroot -b

The build went fine, and a set of *.deb files is created:

address-book-app_0.4~0ubports1_armhf.deb
qtdeclarative5-ubuntu-addressbook0.1_0.4~0ubports1_armhf.deb
address-book-app-autopilot_0.4~0ubports1_all.deb
qtdeclarative5-ubuntu-contacts0.1_0.4~0ubports1_armhf.deb
address-book-app-dbg_0.4~0ubports1_armhf.deb

From the documentation (https://docs.ubports.com/en/latest/systemdev/testing-locally.html) I gather I need to install the *.deb files using dpkg using:

sudo dpkg -i ../<package>.deb [../<package2>.deb ...] 

I is not clear though in which context, in the conainer or outside of it? If I pull the files from the container and install outside of it I get dependecy problems such as:

phablet@ubuntu-phablet:~$ sudo dpkg -i address-book-app_0.4~0ubports1_armhf.deb
(Reading database ... 51249 files and directories currently installed.)
Preparing to unpack address-book-app_0.4~0ubports1_armhf.deb ...
Unpacking address-book-app (0.4~0ubports1) over (0.4~0ubports1) ...
dpkg: dependency problems prevent configuration of address-book-app:
 address-book-app depends on libqt5core5a (>= 5.10.0); however:
  Version of libqt5core5a:armhf on system is 5.9.5+dfsg-0ubports3.

dpkg: error processing package address-book-app (--install):
 dependency problems - leaving unconfigured
Processing triggers for mime-support (3.59ubuntu1) ...
Errors were encountered while processing:
 address-book-app

This is not surprising really I guess. Setting up the container was manual work, as I could not get the command

sudo apt build-dep address-book-app

to work inside it and could not find an alternative (I wanted to retest that once I managed to actually get the process going from end to end)
However inside the container installation is not possible since there is no sudo and even if I install it, it does not work:

sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set

Any further help would be greatly appreciated. Once I understand the container based app development process (which I think is a great idea) I would like to offer to try and document it better.

Hi,

after some fiddling I managed to mostly build the address-book-app in the libertine container. Unfortunately I know next to nothing about debian package build at this moment in time. The build fails with:

dpkg-buildpackage: error: fakeroot debian/rules binary gave error exit status 2

Perhaps some of the knowledgeable people here can help me out where to look for the cause of this error.

@jezek good idea actually, I will give that a try.

@dobey Thanks, I already started going down that route after some initial head scratching.
