[Gate-users] Unable to run Gate; Halp

[David Sarrut]

Hello,

you need "./" before because on unix OS (linux, mac), the command you type
is searched in some folders only, listed in a variable named "PATH". The
folder of your Gate executable is probably not in the path, so you need to
specify where is the command ("./" means in the current folder). Several
Gate executables may be at the same times on the computer, it could be
useful to compare versions.

libCore.so is shared library (from Root), again the path to this library
must be known by the terminal. On linux it is stored in the LD_LIBRARY_PATH
variable. so, something like:
export LD_LIBRARY_PATH=<my_path_ro_root_lib>  could help
In http://wiki.opengatecollaboration.org/index.php/Compilation_
Instructions_V7.2 you will see that source /PATH_TO/root_v5.XX/bin/thisroot.sh
should set everything for you.

HTH,
David
