First of all thank you for your help.
for your first question, I just want to run the following simple code
Map tMap (dImageWidth, dImageHeight);
/ / Init area
tMap.zoomToBox (Envelope <double> (dZoneMinX,
dZoneMinY, dZoneMaxX, dZoneMaxY));
/ / Buffer
Image32 buf (tMap.getWidth (), tMap.getHeight ());
/ / Made this area into a buffer in memory
agg_renderer <Image32> ren (tMap, buf);
ren.apply ();
2em the question:
ogr gdal the library I used in my project for other purposes.
but they do not interact in the crash.
but you wanted to say
"
I bet if the boost threading library Was Was Built,
aim for mapnik You Need to pass compile flags like:
-DBOOST_SPIRIT_THREADSAFE-DMAPNIK_THREADSAFE
and at least with gcc also-ftemplate-depth-100
"
??
