=== What is [[https://developer.chrome.com/multidevice/data-compression|Google Data Saver]]? ===

<note tip>
Chrome sends requests via Google proxy server via [[wp>SPDY]]. This proxy server optimizes the content (image transcoding, CSS/JavaScript compression) and compresses the output.

<note question>
First problem:
<code console>
$ /opt/google/chrome/chrome
/opt/google/chrome/chrome: error while loading shared libraries: libbz2.so.1.0: cannot open shared object file: No such file or directory
</code>

Second problem:
<code console>
$ /opt/google/chrome/chrome
/opt/google/chrome/chrome: symbol lookup error: /opt/google/chrome/chrome: undefined symbol: FT_Get_Advances
</code>

Third problem:
<code console>
$ /opt/google/chrome/chrome
Segmentation fault
</code>
</note>
<note tip>
  * First problem can be solved by symlinking the necessary library: \\
    ''cd /lib64 && ln -s libbz2.so.1.0.5 libbz2.so.1.0''
  * Second problem is solved by installing Freetype library from OpenSuSE 11.4 (see also [[http://productforums.google.com/forum/#!msg/chrome/2RMhirOM-VE/kCZuC9gUIJoJ|Google Chrome Forum]]): \\
    ''rpm -U libfreetype6-2.4.11-85.1.x86_64.rpm freetype2-devel-2.4.11-85.1.x86_64.rpm''
  * Third problem has no solution yet. That means v27 crashes, and v28 and later have the following dependency: \\
    ''xorg-x11-libX11 >= 7.6_1''
