[Dune] Problem with installation

[Lars Diening]

Hi Christoph,

thanks for your fast answer (at bottom).

I already installed gcc-4.9 yesterday as follows:

--

|sudo add-apt-repository ppa:ubuntu-toolchain-r/test sudo apt-get update 
sudo apt-get install gcc-4.9 g++-4.9 sudo update-alternatives --install 
/usr/bin/gcc gcc /usr/bin/gcc-4.9 60 --slave /usr/bin/g++ g++ 
/usr/bin/g++-4.9|

--

The command "gcc --version" gives

--
gcc (Ubuntu 4.9.3-8ubuntu2~14.04) 4.9.3

Then I run:
dune-common/bin/dunecontrol all

I still get the same error:

   By not providing "FindVc.cmake" in CMAKE_MODULE_PATH this project has

CMake did
   not find one.

   Could not find a package configuration file provided by "Vc" with any of

   Add the installation prefix of "Vc" to CMAKE_PREFIX_PATH or set 
"Vc_DIR" to
   a directory containing one of the above files.  If "Vc" provides a 
separate
   development package or SDK, be sure it has been installed.

What should I do?

Best wishes,
