I was trying to run a flutter app on Ubuntu 22.04 LTS. Everything was working fine. But, today this problem came up while running the app. The Flutter SDK fails to build the app throwing the below error.
/snap/flutter/130/usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/../../../../lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.33' not found (required by /usr/lib/x86_64-linux-gnu/gio/modules/libgvfsdbus.so)
Failed to load module: /usr/lib/x86_64-linux-gnu/gio/modules/libgvfsdbus.so
After searching on the internet I realized I need a backward version of libc. If I do file /snap/flutter/130/usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/../../../../lib/x86_64-linux-gnu/libc.so.6.
I get the result /snap/flutter/130/usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/../../../../lib/x86_64-linux-gnu/libc.so.6: symbolic link to libc-2.31.so.
Probably I need to install libc-2.31. But, how? I did not find any solution. Both Flutter and Ubuntu are upgraded to the latest versions.
It's a snap problem with vscode.
First remove vscode :
sudo snap remove code
Then download the .deb of vscode here : https://code.visualstudio.com/docs/setup/linux
And install it with :
sudo apt install ./<file>.deb
moving to edge channel, snap refresh flutter --edge
running flutter upgrade
deleting build directory rm -r build/
running the application again flutter run -d linux
reference this
I had this problem. I just uninstalled and reinstalled flutter. It worked nice.
snap remove flutter
snap install flutter
flutter doctor
After searching on the internet I realized I need a backward version of libc.
No, you don't.
The error means: the version of GLIBC you are using is too old and does not satisfy requirements of the system libgvfsdbus.so which you are trying to load.
Your application appears to be using a custom version of GLIBC, located in /snap/flutter/130/lib/x86_64-linux-gnu/libc.so.6, which is older than the system-installed GLIBC (which is likely 2.33 or newer).
I don't know whether Flutter makes you use a custom GLIBC, or whether you chose to do so on your own. Either way, this seems like a terrible idea.
If you must use custom GLIBC for this app, then you should not use any system libraries (such as /usr/lib/x86_64-linux-gnu/gio/modules/libgvfsdbus.so) in it.

Flutter application is extremely slow on linux. The performance tab shows 15fps and it never goes beyond that. I was unable to find any explanation or possible solution for this issue. Any suggestions?
clang version 10.0.0-4ubuntu1/
cmake version 3.16.3/
ninja version 1.10.0/
pkg-config version 0.29.1/
OS : Fedora Linux
For anyone potentially running into the same problem, this was either an issue with my OS or my flutter SDK. I initially installed the SDK using snap but after reinstalling my OS I installed it by cloning the github repo and setting the path variable etc... (the way explained in the official website) and the issue was resolved.
A similar question has already been asked here Starting with KDE Frameworks 5 and Qt Creator. However, the answer still hasn't clarified my doubts. So here is the problem: on Linux (Ubuntu) there are two ways to install Qt, first is to use apt (sudo apt install qt5-default) and the other one is to download Qt from the official website. Now when you install using the first way Qt is installed by defualt /usr/lib and the second way in the home folder (or in /opt if you ran the installed with administrator privileges).
Now I would like to integrate KDE Frameworks 5 in my project so on the official website it is suggested to use:
sudo apt install framework
And then you can just include that in your project by QT += framework. The problem is I installed Qt using the second way (downloading from the website) and as a result Qt Creator always return Project ERROR: Unknown module(s) in QT: framework. This I believe is because Qt doesn't seem to be aware of the fact that the modules are in /usr/lib/x86_64-linux-gnu/qt5/mkspecs/modules/ instead it probably looks for them somewhere else.
How do I solve this problem with a permanent solution? I cannot install Qt using apt because I would like to use the latest version which usually in not immediately available in the default repositories.
Ok so after a looking a lot, a solution has been suggested here https://forum.qt.io/topic/104861/how-to-use-kde-frameworks-with-qt-creator/8
Essentially Qt, if not installed through the system's repositories, is unable to find the KF5 modules. In order to fix this you can add a QMAKEPATH environment build variable to your project that tells Qt where it should look for the module, in my case this was in
/usr/lib/x86_64-linux-gnu/qt5
I am using Intellij IDEA 2017.2.5 on Linux Mint 18.2 and trying to add new openjdk-9 SDK but IDEA does not accept openjdk 9 as valid JDK:
I have installed all of my SDKs using apt-get from ppa standard repositories.
This is my update-alternatives --config java/javac output:
Although Intellij declared it would support JDK 9 here, but it seems it is not yet fully compatible with at least opensdk-9.
Maybe refactoring SDK directory and removing 'jre' folder misleads the IDEA to find the SDK 9 home folder.
Any idea why Intellij IDEA claims 'The selected directory is not a valid home for JDK' ?
“ Ubuntu PPA for OpenJDK” currently has very old build of openjdk-9(9~b115-1ubuntu1).
So the IDEA does not recognize it as a valid SDK.
I removed current installed version:
sudo apt-get remove '^openjdk-9.*'
Then I have downloaded newer .deb build(9~b181) files including jre,jre-headless,... from launchpad build archive.
sudo dpkg -i openjdk-9-jre-headless_9_b181-4_amd64.deb
openjdk-9-jre_9_b181-4_amd64.deb
openjdk-9-jdk-headless_9_b181-4_amd64.deb
openjdk-9-jdk_9_b181-4_amd64.deb
Just Execute the above command at a single line, line breaks are for better readability.
Ignore any error complaining about:
"Package libpng16-16 is not installed."
Next execute the following:
sudo apt-get install -f
Now after installing this build of openjdk-9 the IDEA is happy with SDK home.
Thanks #y.bedrov for his useful comment.
Update:
However this solution enables you to declare openjdk-9 in the mentioned IDEA version(2017-2) but you are not able to compile any class within the IDEA itself.
You can only compile your application with elder jdk and run it with openjdk-9. There is an other issue which indicates this here.
In the newer IDEA versions(I have tested 2017.3) this build of openjdk is not allowed to be used as new SDK any more, see this issue.
The short reason is an issue in Debian package which contains incorrectly compiled lib/jrt-fs.jar file.

I want to add Doxygen plugin to QtCreator.
I am using QtCreator 2.5.2 in ubuntu 12.10 and the latest Doxygen version for QT is 2.4.0.
I've changed the doxygen.pluginspec file to get rid of version error.
But now I've got another error:
can not load library libdoxygen.so (libQtconcurrent.so can not open shared object file:No such file or directory)
Any suggestion would be appreciated.
I hope you are no longer stuck, but if not, I will still try to help.
Yes, the quick install binaries are available only for QtCreator 2.4, but the plugin stays easy to install without it : you have to download the sources and build them yourself, as written in the wiki.
Moreover, you have to build it with the same version of Qt4 as the one that was used for build your QtCreator (have a look here)
It became compatible with QtCreator 2.7 and Qt5 at the end of March, and I succeeded in installing in in QtCreator2.8-beta.
If you have any other question, I guess it would be better to ask them in the plugin forum where developpers always answer to people in need.
Hope this helps (you and other people in need).
You can install Doxywizard wich provides an user interface to use Doxygen.
I'm not shure I'm using fedora to install I used.
yum install doxygen-doxywizard.x86_64.
For Ubuntu it should be if the package name is the same.
apt-get install doxygen-doxywizard.x86_64
(as root)
I have installed Node.js on an Ubuntu 64bit server using a standard apt-get and would like to profile scripts through the "--prof" flag.
Web searching shows there should be a tool to process the v8.log output located in "deps/v8/tools/linux-tick-processor" but I don't seem to have any of those directories. Do they come with the native install? should they be installed separately? if so how?
Thank you
You need to download the source package with sudo apt-get source nodejs.The path you mentioned is in there.
You'll need to scons prof=on d8 in deps/v8 to build the debugger first, which might have some trouble on a 64-bit machine (v8 is 32-bit only), see here for more info.
Here's how I did it for Node.js 0.10.25 and 0.10.26:
I downloaded the source for Node.js that corresponds to the binaries I'm using. (I'm on Debian testing, which is a bit behind the releases from the Node.js web site.)
I checked the version of v8 bundled in the node sources. (Look at deps/v8/ChangeLog. It was 3.14.5 for Node.js 0.10.25 and 0.10.26.)
I downloaded this exact version of v8 from the v8 site.
Why? I tried running make native in Node.js deps/v8 directory but the Makefile was complaining about a missing test directory. From this we can infer that the Node developers are not including the entire v8 distribution. Once upon a time, with an earlier version of Node (0.8.something) I did build v8 from what was available in deps/v8 but this time I decided to use a different approach.
As explained in v8's build/README.txt, in the top level of the source tree for v8, I did:
$ svn co http://gyp.googlecode.com/svn/trunk build/gyp
(Linking my installed gyp to build/gyp as suggested in OrangeDog's answer did not work. That's why I did the above.)
I ran:
$ CXX=g++-4.7 make native
Why the CXX setting? I ran into a compilation problem right away when I tried with the default gcc. I checked the version. It was 4.8 and I remembered a story on Slashdot about how 4.8 was giving people trouble. So I installed 4.7. Worked fine.
I linked out/native/d8 to a location which is in my PATH. This is because the linux-tick-processor script does a poor job at finding d8. The simplest solution was to make it available in my PATH. Your mileage may vary.
After all this, linux-tick-processor can be used with the v8.log files that Node produces.
Either install the source package - sudo apt-get source nodejs, or switch to the official source as the ubuntu packages are very out of date.
To build d8, go to the deps/v8 directory.
Create a symlink at build/gyp to the directory where gyp can be found (e.g. /usr/bin).
Run make native.
Copy/symlink out/native/d8 to somewhere on your PATH.
