# Minimal Makefile for building DCD and NAMDBIN file format shared

# The code distributed with this Makefile is bundled with VMD and
# licensed under the UIUC open source license (see LICENSE).  The
# plugins are being redistributed (along with their headers) to avoid
# depending on all of VMD's code base and build process. If you have
# trouble with this Makefile, download and build the latest VMD
# distribution.

# To integrate in MSMBUILDER, only dcdplugin_s.c and include files
# are required. They will be built by the setup.py script.

# xxx_s.c is an ugly hack to work-around the register-callback
# machinery: makes all static functions /directly/ callable from
# python. Normally they would be exposed through a the
# molfile_plugin_t structure containing function pointers. Using
# callbacks from python is cumbersome and requires to maintain a
# python version of the (non-trivial) struct.  THIS WILL BREAK ANY
# STATIC VARIABLE IN FUNCTION BODIES! On the other hand, there should
# be no function name conflict, since ctypes requires the caller to
# explicitly state the DLLs of each function to be called.
