37 * Version information for software that links to \Gromacs.
40 * This include file will be configured by CMake and contains version
41 * information. It is not used by \Gromacs, but intended for software that
43 * The values come from the main CMakeLists.txt.
46 * This file exists from 4.6 onward, and can be included as
47 * `<gromacs/version.h>`. In 4.6, it is also included by
48 * `<gromacs/typedefs.h>, but that header has already moved in 5.0.
50 * This header defines two values, the \Gromacs version, and the API version.
51 * The versions are in numerical form, where, for example, version
52 * 4.6.1 would be 40601.
54 * The API version is defined in ::GMX_API_VERSION, and denotes the
55 * version of the programmer interface, i.e. the installed header files
56 * and compatible library.
58 * Programs written against the \Gromacs library can use this file
59 * to provide some backward compatibility even though parts of the API
60 * change. For example:
62 #include <gromacs/version.h>
63 #if (GMX_API_VERSION < 50000)
64 .... <do pre-5.0 stuff>
66 .... <do post-5.0 stuff>
69 * where version.h is included directly. For code that must be compatible
70 * between 4.5 and 4.6, an interim solution is to include typedefs.h, which
73 #include <gromacs/typedefs.h>
74 #if !defined(GMX_API_VERSION) || (GMX_API_VERSION < 40600)
75 .... <do 4.5 specific stuff>
76 #elif (GMX_API_VERSION < 40700)
77 .... <do 4.6 specific stuff>
87 * API version of this set of \Gromacs headers.
89 * If there are multiple versions of \Gromacs that work with the same set of
90 * headers, then this version is not updated between the versions, even though
92 * For 4.6 and 5.0 (and likely for some time in the future as well), this
93 * tracks the exact \Gromacs version.
95 #define GMX_API_VERSION @GMX_API_VERSION@
98 * Exact \Gromacs version of this set of headers.
100 * This specifies the version number of the actual \Gromacs library that
101 * installed these headers.
103 #define GMX_VERSION @GMX_VERSION_NUMERIC@
