QtWebEngineProcess error #34

mytskine · 2016-10-20T12:24:10Z

I applied linuxdeployqt to a custom build of otter-browser. The AppImage is sucessfully built, but when I run it on another sytem, it fails with the message "QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled".

I first used linuxdeployqt-1-x86_64.AppImage, then I used the latest linuxdeployqt from git, with the latest AppImageAssistant. In this case, the image failed with the message "Could not find QtWebEngineProcess".
Here are the libraries that are not packaged by the AppImage when I use linuxdeployqt otter-browser -libpath=/home/vagrant/Qt/5.7/gcc_64/lib -verbose=2 -appimage -bundle-non-qt-libs:

As a side note, when there is no .desktop file, the command linuxdeployqt silently fails with an apparent success.

Another surprise was that the resulting file was named ..AppImage which is a very uncommon and hidden name. I suspect the intended name was ../AppImage.

The text was updated successfully, but these errors were encountered:

probonopd · 2016-10-20T16:41:38Z

tl;dr: We must implement https://doc-snapshots.qt.io/qt5-5.7/qtwebengine-deploying.html

I think QtWebEngineProcess is a binary that doesn't get bundled by appimagetool yet. Which is a bug. The name of the AppImage is also wrong, it should be the name of the AppDir plus .AppImage.

probonopd · 2016-10-20T22:23:32Z

Hypothesis (to be verified): When libQt5WebEngineCore.so is going to be deployed, then the 5.7/gcc_64/libexec/QtWebEngineProcess executable (and its dependencies) need to be deployed as well.

mytskine · 2016-10-21T08:20:54Z

Many thanks, your hypothesis was right, unfortunately there are other steps to build a valid image.

I copied the directory 5.7/gcc_64/libexec/(which only contains QtWebEngineProcess) into the directory to package.
I added -executable=libexec/QtWebEngineProcess to the linuxdeployqt command.
The AppImage did not work because of missing i18n libraries, so I added Qt/5.7/gcc_64/lib/libicu* under lib/.
Now the AppImage fails because of missing i18n data.

I put Qt/5.7/gcc_64/resources/* under the resources/ directory and packaged it again.
It still crashes right after it starts, but I don't understand what the problem is with libsoftokn3.so (which is part of the libnss3 package, installed on my target system).

[1021/095423:ERROR:nss_util.cc(740)] Error initializing NSS with a persistent database (sql:/home/username/.pki/nssdb): libsoftokn3.so: cannot open shared object file: No such file or directory

I can't even find which executable/library requests this: I applied ldd $(find . -name "*.so" -or -type f -and -executable) | grep softokn3 without any match.

probonopd · 2016-10-21T15:38:40Z

Please do grep -r softokn3 . inside the AppDir - does it print anything?

mytskine · 2016-10-21T17:14:20Z

lib/libnss3.so was the culprit!

Anyway, this doesn't solve much, because the same fatal error occurs even if I package libsoftokn3.so.

[1021/185717:ERROR:nss_util.cc(740)] Error initializing NSS with a persistent database (sql:/home/username/.pki/nssdb): NSS error code: -8023

The directory ~/.pki/nssdb does exist and has rx access. I don't intend to debug NSS, so I'll drop this attempt, unless you have some suggestions? Thanks anyway.

probonopd · 2016-10-21T17:15:37Z

What happens if you delete lib/libnss3.so from the AppDir?

mytskine · 2016-10-21T17:51:12Z

After removing libnss3.so:

After also removing libnssutil3.so:

./otter-browser-x86_64.AppImage: symbol lookup error: /usr/lib/x86_64-linux-gnu/libnss3.so: undefined symbol: PR_GetEnvSecure

After also removing libsoftokn3.so:

[1021/193936:ERROR:nss_util.cc(211)] Error initializing NSS without a persistent database: NSS error code: -5925

probonopd · 2016-10-22T07:37:02Z

I would assume NSS is pretty low level software that should be part of any target system and hence not bundled inside the AppImage; I might be wrong though. We need to figure out the entire dependency graph and decide what to bundle and what not to bundle. Does my Otter AppImage at https://bintray.com/probono/AppImages/Otter#files suffer from the same issues? It was not built using linuxdeployqt, so maybe it can help us figure out what should and should not be bundled by linuxdeployqt.

mytskine · 2016-10-22T08:50:07Z

Your image is compiled against Qt5WebKit, while mine uses QtWebEngine which is the preferred way to build Otter beta11. That shows your executable was compiled against an old release of Qt, since libQt5WebKit.so is not part of the last release (Qt 5.7). So the chromium engine in your AppImage is a bit old. That's one of the reasons why I wanted to rebuild this package. IIRC, that's also why there is no Ubuntu package of the latest Otter release (Qt 5.7 and QtWebEngine are not packaged by Debian/Ubuntu).

Anyway, your AppImage fails to start on my Debian testing amd64:

zenity, kdialog, Xdialog missing. Skipping ./bin//otter-browser.wrapper.
/tmp/.mount_E6YnI7/usr/bin/otter-browser: ../lib/x86_64-linux-gnu/libgpg-error.so.0: no version information available (required by /lib/x86_64-linux-gnu/libgcrypt.so.20)

probonopd · 2016-10-22T09:51:25Z

Yes, I my AppImage merely repackages the deb from the ppa. Already found out that bundling libgpg-error.so.0 does more harm than good. Anyway, need to solve the real issue of this ticket ;)

probonopd · 2016-10-22T12:46:52Z

I can produce a working Otter AppDir using linuxdeployqt, however it involves manual copying of files linuxdeployqt should deploy automatically:

export PATH=/tmp/.mount_QtCreator-5.7.0-x86_64/5.7/gcc_64/bin/:$PATH
qmake -v # Check that the correct Qt path is shown

# This *SHOULD* be done automatically by linuxdeployqt, I need to figure out how
cp -r /tmp/.mount_QtCreator-5.7.0-x86_64/5.7/gcc_64/libexec $HOME/build-otter-browser-Desktop_Qt_5_7_0_GCC_64bit-Default/
mkdir -p $HOME/build-otter-browser-Desktop_Qt_5_7_0_GCC_64bit-Default/resources
cp -r /tmp/.mount_QtCreator-5.7.0-x86_64/5.7/gcc_64/translations/qtwebengine_locales $HOME/build-otter-browser-Desktop_Qt_5_7_0_GCC_64bit-Default/resources
cp /tmp/.mount_QtCreator-5.7.0-x86_64/5.7/gcc_64/resources/icudtl.dat $HOME/build-otter-browser-Desktop_Qt_5_7_0_GCC_64bit-Default/resources/

# Rerun linuxdeployqt from git
./linuxdeployqt/linuxdeployqt/linuxdeployqt ./build-otter-browser-Desktop_Qt_5_7_0_GCC_64bit-Default/otter-browser -verbose=3

# Runs!

However, when I use the -appimage switch, the AppImage fails with [1022/144633:ERROR:nss_util.cc(740)] Error initializing NSS with a persistent database (sql:/home/me/.pki/nssdb): libsoftokn3.so: cannot open shared object file: No such file or directory which is a separate issue.

probonopd · 2016-10-22T13:42:17Z

Possibly fixed in 3415b30, please confirm

mytskine · 2016-10-31T20:43:01Z

Sorry for the delay. I just used the new version of linuxdeployqt, and the result was the same as described in the comment #34 (comment). This isn't surprising, since the the new linuxdeployqt copies the same files that I did manually. Now I'll have to wait for a fix of #35. Many thanks for your help.

probonopd · 2016-11-04T15:48:44Z

@mytskine can you advise me what to do?
