Ubuntu – Error libx264 not found

software installation

I follow this installation guide. At step 3 (Install Dependencies):

sudo ./licode/scripts/installUbuntuDeps.sh in terminal

But while compiling it throws error libx264 not found Why I got this error, and how to solve it?

It happens because you are compiling libav with --enable-libx264 which would need the libx264 headers to complete. It fails at the configure phase with:

configure: error: libx264 not found

This can be fixed easily installing the needed headers package libx264-dev which should be done with sudo apt-get install yasm libvpx. libx264. but for some reason it doesn't for you:

sudo apt-get install yasm libvpx. libx264.

libvpx-dev is already the newest version.
libvpx1 is already the newest version.
libvpx1 set to manually installed.
yasm is already the newest version.
libx264-142 is already the newest version.

Ubuntu – Avagadro 1.2 ubuntu 16 installation error. CMAKE make

You can see revisions of this answer to get confirmation that 1.2 version does not compile on Ubuntu 16.04 LTS because of problems with OpenBabel functions and related dependencies.

So we consider to use schroot mechanism. It will create small 18.04 LTS system inside your existing 16.04 LTS system. Both will use the same filesystem.

To setup schroot you need to execute the following commands (just copy and paste them):

sudo apt-get install schroot debootstrap -y

cat <<EOF | sudo tee /etc/schroot/chroot.d/bionic.conf
[bionic]
description=Ubuntu 18.04
directory=/srv/chroot/bionic
root-users=$USER
type=directory
users=$USER
EOF

sudo mkdir -p /srv/chroot/bionic
sudo debootstrap bionic /srv/chroot/bionic

cat <<EOF | sudo tee /srv/chroot/bionic/etc/apt/sources.list
deb http://archive.ubuntu.com/ubuntu bionic main restricted universe multiverse
deb http://security.ubuntu.com/ubuntu bionic-security main restricted universe multiverse
EOF

schroot -c bionic -u root apt-get update
schroot -c bionic -u root apt-get install avogadro

To run Avogardo 1.2 from terminal you need to run:

schroot -c bionic env DISPLAY=:0.0 avogadro

Optionally you can create Avogadro.desktop file for it and place it on Desktop:

cat <<EOF > ~/Desktop/Avogadro.desktop
[Desktop Entry]
Version=1.2
Name=Avogadro
GenericName=Advanced molecular editor
Comment=Molecular Graphics and Modelling System
Exec=schroot -c bionic env DISPLAY=:0.0 avogadro
Icon=/srv/chroot/bionic/usr/share/pixmaps/avogadro-icon.png
Terminal=false
Type=Application
Categories=Qt;Science;Chemistry;Physics;Education;
StartupNotify=true
MimeType=chemical/x-cif;chemical/x-cml;chemical/x-daylight-smiles;chemical/x-gamess-input;chemical/x-gamess-output;chemical/x-gaussian-log;chemical/x-mopac-out;chemical/x-pdb;chemical/x-xyz;chemical/x-gaussian-checkpoint;chemical/x-gaussian-cube;chemical/x-qchem-output;
EOF

chmod +x ~/Desktop/Avogadro.desktop

And enjoy the application:
