If you choose the default installation paths, then your install of
Geant4 is completely contained under the directory you chose for
CMAKE_INSTALL_PREFIX, with the structure
+- CMAKE_INSTALL_PREFIX +- bin/ | +- geant4-config (UNIX ONLY) | +- geant4.csh (UNIX ONLY) | +- geant4.sh (UNIX ONLY) | +- G4global.dll (WINDOWS ONLY) | +- ... +- include/ | +- Geant4/ | +- G4global.hh | +- ... | +- CLHEP/ (WITH INTERNAL CLHEP ONLY) | +- tools/ +- lib/ (MAY BE lib64 on LINUX) | +- libG4global.so (AND/OR .a, OR G4Global.lib ON WINDOWS) | +- ... | +- Geant4-9.6.0/ | +- Geant4Config.cmake | +- Geant4ConfigVersion.cmake | +- Geant4LibraryDepends.cmake | +- Geant4LibraryDepends-Release.cmake | +- UseGeant4.cmake | +- Linux-g++ (OR Darwin-g++ UNIX ONLY SOFTLINK -> ..) | +- Modules/ +- share +- Geant4-9.6.0 +- data/ (IF GEANT4_INSTALL_DATA WAS SET) +- geant4make/ +- geant4make.csh +- geant4make.sh +- config/
To make the Geant4 binaries and libraries available on your
PATH and library path
LD_LIBRARY_PATH on Linux,
DYLD_LIBRARY_PATH on Mac OS X),
you should source the relevant script in
On interactive bourne shells (e.g. bash), do (assuming you are
$ . geant4.sh
This command can also be used to setup the Geant4 environment in other Bourne shell scripts. You can also supply the full path to the script rather than changing to the directory containing it.
On interactive C shells, do (assuming you are
$ source geant4.csh
In an interactive session you can also supply the full path to the script rather than changing to the directory containing it. The C shell script cannot be sourced directly inside other shell scripts due to a limitation of this shell which prevents the script being able to locate itself. If you need to source the C shell script inside another, then you can use the command
cd CMAKE_INSTALL_PREFIX/bin ; source geant4.csh
where you should replace
with the directory you installed
You can also use the command
source CMAKE_INSTALL_PREFIX/bin/geant4.csh CMAKE_INSTALL_PREFIX/bin
where as above you should replace
with the directory where
geant4.csh is located.
On Windows, you should add the directory containing the Geant4 dll files to your PATH environment variable. On Windows 7/XP, this can be done via the Control Panel as follows
Open the Windows Control Panel.
Open the System item in the Control Panel.
Click on the Advanced system settings link on the System window (on Windows XP, click on the Advanced tab).
Click on the Environment Variables button in the System Properties window.
PATH entry in the User
variables list, and click the Edit
is not present, click on the New
and create it.
In the popup Edit User Variable window,
append the directory in which the Geant4 dlls are installed to
the Variable value entry of the
(Note that on Windows, path entries are separated by semicolons).
It's very important to append the Geant4 dll path if you have an
PATH, otherwise other programs may
stop working correctly! If the Variable value entry of the
PATH variable is empty, or you've just created
it, you can simply set the value to the directory in which the
Geant4 dlls are installed. Once you have edited,
