There are some traps when deploying on linux, so please read the following instructions carefully especially the Red Words
Download linux version PGAP-X file.
Uncompress the file to any directory you want(say: ToolDir).
Pay attention to the version of your operation system(i386/x86 or x64).
Enter the directory.
Make sure all applications are executable by using command "chmod +x pgapx" and "chmod +x ./thirdparty/*" .
Use command "./pgapx" in terminal to run.
Pay attention do not use any blank or space in your directory. You can use numbers[0-9], letters[a-zA-Z] and underline in your directory, but no other characters say Chinese language or any space.
All Done, Cool!
