<div dir="ltr">Hello, <div><br></div><div>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. </div><div><br></div><div>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:<br></div><div>export LD_LIBRARY_PATH=<my_path_ro_<wbr>root_lib> could help</div><div>In <a href="http://wiki.opengatecollaboration.org/index.php/Compilation_Instructions_V7.2" target="_blank">http://wiki.<wbr>opengatecollaboration.org/<wbr>index.php/Compilation_<wbr>Instructions_V7.2</a> you will see that source /PATH_TO/root_v5.XX/bin/<wbr>thisroot.sh should set everything for you. </div><div><br></div><div>HTH,</div><div>David<br></div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Dec 7, 2016 at 5:31 AM, Robert Wilson <span dir="ltr"><<a href="mailto:rkwilson@mail.sdsu.edu" target="_blank">rkwilson@mail.sdsu.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div><div>Hello.

Neither however would run from the simple command "Gate".
