Re: [mapserver-users] Mapserver + regex license
I don't see any issues I guess in the docs we could point folks to the PCRE implementation as well as the GNU one http://vcs.pcre.org/viewvc/code/trunk/pcreposix.h?view=markup PCRE's license is BSD Norman On Jan 18, 2012, at 10:54 AM, Lime, Steve D (DNR) wrote: > I'm hoping someone with experience in this area can chime in.

MapServer doesn't contain code from any regex library, it uses an API that a few regex libs support so you can actually compile against others. Steve Steve / Josef, First, as Steve suggests the issue only arises if you build with the GPL'ed regex 0.12. Second, requirements for redistribution of source in the GPLv2 only apply if you distribute MapServer binaries to clients or users (as opposed to putting up a service on your own servers that outsiders use). Third, the redistribution of source requirements is normally considered to only apply to code linked into the executable. While this is a bit of a grey area, it would not normally apply to the PHP/Python/Perl scripts using the mapscript api. So you are likely in the clear.

RE: [mapserver-users] Mapserver + regex license
I'm hoping someone with experience in this area can chime in. It's a convoluted subject for sure. MapServer doesn't contain code from any regex library, it uses an API that a few regex libs support so you can actually compile against others.
