[Gate-users] How to compile a new geometry class?

[David Sarrut]

Hello,

if you envisaged to add some specific volume to Gate, here are some hints:

- You should create a class that derive from GateVVolume
<https://github.com/OpenGATE/Gate/blob/develop/source/geometry/src/GateVVolume.cc>
- Take for example an GateBox
<https://github.com/OpenGATE/Gate/blob/develop/source/geometry/src/GateBox.cc>
(or
other) as template, copy the 4 files GateBox.cc/hh +
GateBoxMessenger.cc/hh, of course change the class & file name
- Take care to the two macros: FCT_FOR_AUTO_CREATOR_VOLUME
and MAKE_AUTO_CREATOR_VOLUME in the hh file, those "magic" lines will allow
for your new volume to be automatically
compiled and recognised
- When adding files for the first time, run cmake before make.
- I highly highly highly recommend to start any modification from a new git
branch (derived from the develop <https://github.com/OpenGATE/Gate> branch)

When you are happy with the result, feel free to propose a pull-request so
that your new volume could be integrated in the next version and useful for
others

HTH,
David
