[mapserver-dev] PHP Mapscript

Mon Oct 8 01:51:04 PDT 2012

If I may come back to this topic: I want to share my php_mapscript 
compile errors when doing make. Maybe there's a hint hidden. If you 
please want to have a look at the error messages and provide some 
feedback if the errors are 'normal' or there's a real problem.

Another thing I noticed: I can create other objects without having a 
segfault. For example, rectObj or pointObj seem to work fine. Even 
layerObj tells me that it needs a mapObj for initialisation instead of 
segfaulting.

Thanks,

Frank
