[MapServer-dev] librsvg2 version

[Johannes Paul]

Actually the error seems to be related to this commit in mapcairo.c on
branch 8.6
https://github.com/MapServer/MapServer/commit/4121426f071bc0f090f203569cc31bd3feca92b9

RsvgRectangle type is used here
https://github.com/MapServer/MapServer/blob/branch-8-6/src/mapcairo.c#L371
and here
https://github.com/MapServer/MapServer/blob/branch-8-6/src/mapcairo.c#L1131
without checking for the librsvg version using LIBRSVG_CHECK_VERSION

So now Mapserver cannot build with librsvg < 2.46.0 anymore ...
