    Hi Hermann,<br>
    <br>
    Thank you very much for your reply. Using root version 5.34 solved
    the problem!<br>
    <br>
    For the record, the following installation was successful on Ubuntu
    14.04 with gcc v4.8.2:<br>
    - root v5.34.24<br>
    - geant4 v4.9.6.p03<br>
    - gate v7.0<br>
    <br>
    Cheers,<br>
    Martin<br>

      Hi Martin,<br>
      <br>
      this is due to an incompatibility with the newest root version.<br>
      Try using an older root version such as version 5.34.<br>
      <br>

          <pre class="k9mail">Dear GATE users,

I am trying to installl GATE v7.0 on my computer with Ubuntu 14.04 and 
gcc version 4.8.2. I have successfully installed root v6.02.02 and 
geant4 v10.01.

During the compilation of GATE, I get the following error:

"[  6%] Building CXX object CMakeFiles/Gate.dir/<a moz-do-not-send="true" href="http://Gate.cc">Gate.cc</a>.o

This support is currently experimental, and must be enabled with the 
-std=c++11 or -std=gnu++11 compiler options."

Does anyone know how to solve this problem? Where can I enable those 
compiler flags (-std=c++11 or -std=gnu++11)?


Thank you so much for you help,
Martin
