I am trying to use GStreamer in Ubuntu 16.04, and I need something like this:
gst-launch-1.0 -v tcpclientsrc host=x.x.x.x port=5000 ! gdpdepay ! rtph264depay ! avdec_h264 ! ffmpegcolorspace ! autovideosink sync=false
however when I type gst-inspect-1.0 avdec_h264 or any of the plugins in the list, it results in No such element or plugin
I already tried installing libav, ugly, bad, good:
sudo apt-get install gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-plugins-base gstreamer1.0-plugins-bad gstreamer1.0-plugins-good
Reading package lists... Done

gstreamer1.0-plugins-base is already the newest version (1.8.3-1ubuntu0.2).
gstreamer1.0-plugins-good is already the newest version (1.8.3-1ubuntu0.4).
gstreamer1.0-libav is already the newest version (1.8.3-1ubuntu0.2).
gstreamer1.0-plugins-bad is already the newest version (1.8.3-1ubuntu0.2).
gstreamer1.0-plugins-ugly is already the newest version (1.8.3-1ubuntu0.1).
The following packages were automatically installed and are no longer required:

Use 'sudo apt autoremove' to remove them.
0 to upgrade, 0 to newly install, 0 to remove and 54 not to upgrade.
I also looked in /usr/lib/x86_64-linux-gnu/gstreamer-1.0, and found nothing
Any suggestions on what could be wrong?
If you have anaconda installed and you do which gst-launch-1.0, it will most likely point to anaconda location which only had gst-plugins-base. So directly launching the /usr/bin/gst-launch-1.0 fixed the issues for me as it was able to find the bad, good etc plugins.

I used cmake to build my project. I tried sudo apt-get install libboost-all-dev, but it didn't solve my issue. Is there a way to solve this problem? Thanks.
I had a similar problem, and found that the needed library was installed under the name /usr/lib/<arch>/libboost_python38.so (for x86_64 in my case that's /usr/lib/x86_64-linux-gnu/libboost_python38.so).
So I ran sudo ln -s /usr/lib/x86_64-linux-gnu/libboost_python38.so /usr/lib/x86_64-linux-gnu/libboost_python-py38.so and was able to link OK.
I ran into this specifically when trying to install pygattlib under python 3.8.
I finished this tutorial on Medium in order to integrate my Xcode project with SonarQube to have some metrics. Setup SonarQube - Swift. I was able to make it through the last step that is: running fastlane metrics on the terminal while being in the root of the project directory. But I get this error on step "slather".
nokogiri requires Ruby version >= 2.3.0., fastlane finished with errors:
I have also found that someone had a similar question here, but no answers:

If I run:
nicolas$ ruby --version
I get ruby version 2.6.3, which is higher than the required 2.3
ruby 2.6.3p62 (2019-04-16 revision 67580) [universal.x86_64-darwin19]
Does anyone knows how to fix this, or got any hunches? Thanks in advance, I appreciate any help.
After digging around and trying several solutions, I finally solved this. What happened was that I initially installed Fastlane with this command:
brew cask install Fastlane
And it seems that it was using another version of ruby while I had a newer one. So I uninstalled it with:
brew cask uninstall Fastlane
And then I re-installed it with this command:
sudo gem install -n /usr/local/bin fastlane -NV
Because I was having problems with permissions and then all worked good.

While am compile using swift build, am getting following error in my Ubuntu machine
$swift build
/home/xxxxxxxxx/Downloads/swift-DEVELOPMENT-SNAPSHOT-2016-02-25-a-ubuntu15.10/us
r/bin/swift-build: error while loading shared libraries: libicuuc.so.55: cannot

How can i fix this issue?
Thanks.
You can manually download the good .dep
wget http://security.ubuntu.com/ubuntu/pool/main/i/icu/libicu55_55.1-7_amd64.deb
Then you run:
sudo dpkg -i libicu55_55.1-7_amd64.deb
If it miss some dependency:
sudo apt-get -f install
It has worked for me.
Your can find the other architecture on the debian package website :
https://packages.debian.org/sid/libicu55
p.s: I know this is on SID, but this is the only version that I found
*note...packages may have been removed
Your system lacks a critical component for building Swift, libicu-dev.
Install this:
sudo apt-get install libicu-dev
But that was for building Swift from source. You were talking about building with Swift, my apologies.
Unfortunately it seems it won't work either: Swift for Linux only officially runs on Ubuntu 15.10 and 14.04, and you tell me in the comments that you're running 15.04.
I know there's tutorials on the web on how to make it work on Mint and other distros... But the best would be, if possible, that you update your install of course.
I searched on the net and find a list in debian packages that shows the libicuuc.so.55 file.
apt-get install libicu55
Will resolve the issue.
hallow_me's link to download libicu55_55.1-7_amd64.deb doesn't work.
Here are the latest links https://packages.debian.org/stretch/amd64/libicu57/download
Like
wget http://ftp.us.debian.org/debian/pool/main/i/icu/libicu55_55.1-7_amd64.deb
Then follow hallow_me's instruction to install it.
Try the followings lines
echo "deb http://security.ubuntu.com/ubuntu xenial-security main" | sudo tee --append /etc/apt/sources.list
sudo apt-get update
sudo apt-get install libicu55
Currently running Yosemite and unable to update to ruby 2.1.4 , see below.

Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.10/x86_64/ruby-2.1.4.

/usr/local/bin/brew: /usr/local/Library/brew.rb: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby: bad interpreter: No such file or directory
/usr/local/bin/brew: line 26: /usr/local/Library/brew.rb: Undefined error: 0
ERROR: '/bin' is not writable - it is required for Homebrew, try 'brew doctor' to fix it!
Requirements installation failed with status: 1.
So after I stepped away from the computer for a few hours and came back again, I figured out the issue was that Homebrew was broken after I updated OS to Yosemite. Here is the link http://ryantvenge.com/2014/09/ruby-homebrea-yosemite/ to the solution. If that is not working see commands below.
To fix Homebrew:
cd /System/Library/Frameworks/Ruby.framework/Versions
sudo ln -s Current 1.8
brew update
sudo rm 1.8
To update to ruby 2.1.4:
rvm install 2.1.4
rvm use 2.1.4
Whenever I try to update my system via "sudo yum update", I get this error:
Transaction Check Error:
package libstdc++-4.3.2-7.i386 (which is newer than libstdc++-4.1.2-51.el5.x86_64) is already installed
I'm not sure how I got in this state, but I'm pretty sure that whatever I've done has been through yum.
Here's what "yum list" gives me for that library:
libstdc++.x86_64 4.1.2-50.el5 installed
libstdc++.i386 4.3.2-7 installed
libstdc++-devel.x86_64 4.1.2-50.el5 installed
Notice how the i386 version is different than the .x86_64 version. That's really strange.
I'm running CentOS 5.6 64 bit.
What should I do?
You can use the lazy man's method. For now use --skip-broken so other stuff will update. And eventually your repo version of libstdc++ will catchup to what's on your box.
