Installing Hydro on Debian Linux Note: Reviewed for release 2.7.0. These are detailed instructions for installing Hydro on Debian Linux. They are known to work for a system using Debian Testing distribution. See Download and Install Hydro for general guidelines. Ubuntu\Kubuntu These instructions are also applicable for Ubuntu/Kubuntu 6.10 (Edgy). For Ubuntu/Kubuntu 6.06 (Dapper) you will need to install CMake and Ice separatley. The default version of CMake on Ubuntu/Kubuntu 6.06 is 2.2.3. You will need to download a compatible version of cmake. Version 2.4.3 of cmake has been tested on Ubuntu 6.06. Please see the bottom of this page for instructions on how to build hydro_doc_installdebian_icefromsource. Build Essential # apt-get install build-essential CMake Minimum version required 2.4-patch 2 (latest tested: 2.4-patch 7). # apt-get install cmake IceUtil This library is optional but very useful. From it we use cross-platform well-written threading and timing classes. Minimum version required 3.2.0 (latest tested: 3.2.1). Installing it in Debian is particularly easy because a separate package exists. # apt-get install libiceutil32 For notes on installing other dependencies see Installing some of Hydro's optional dependencies Hydro Build and install Hydro distribution. Download Hydro source archive and un-tar it. The default installation directory is /opt/hydro-[VERSION], where [VERSION] is the Hydro version. You can customized this by setting HYDRO_INSTALL environment variable (e.g. 'export HYDRO_INSTALL=~/hydro'). Configure using cmake . (note the dot after cmake) Compile, and install. If you've changed your mind about the installation directory, you can change it using ccmake tool ('$ ccmake .'). $ tar -zxf hydro-x.x.x.tar.gz $ cd hydro $ cmake . $ make # make install # ldconfig Make sure that the binaries and executables are in the path. You may want to add a snippet to your ~/.bashrc file similar to the one below. Replace [VERSION] with the version of Hydro you've just installed or create a symbolic link called simply hydro (without the version number). Change the directory if you've modified the default install directory. Notice that the environment variable for the Hydro installation to use (HYDRO_HOME) is different from the one which specifies where to install it (HYDRO_INSTALL). This allows multiple installations on the same machine. export HYDRO_HOME=/opt/hydro-[VERSION] export PATH=$HYDRO_HOME/bin:$PATH export LD_LIBRARY_PATH=$HYDRO_HOME/lib:$LD_LIBRARY_PATH That's it! We are done.
