[mapserver-dev] OT: Help is configure

[Daniel Morissette]

You could look at the way the Apache version string is parsed in 
MapServer's configure.in.

To mkae this simpler in the future, perhaps it's time to add 
MS_VERSION_NUM to mapserver.h similar to what we have in GDAL, e.g.

#ifndef MS_VERSION_MAJOR
#  define MS_VERSION_MAJOR    5
#  define MS_VERSION_MINOR    2
#  define MS_VERSION_REV      0
#endif

#ifndef MS_VERSION_NUM
#  define MS_VERSION_NUM 
(MS_VERSION_MAJOR*10000+MS_VERSION_MINOR*100+MS_VERSION_REV)
#endif

Then your code could use

#if MS_VERSION_NUM >= 50200 /* Use OGR Style C API */

If you file a ticket and there are no objections then I'll add this. We 
could also backport to 5.2.1 to make this useful immediately.
