deal with, and is the fastest of the raster formats. (unless something

So you're tiling, and using MS as your backend. Are you using TileCache
or similar in between? If so, TileCache supports meta-tiling which may
help your label problems significantly.
Using meta-tiling, TileCache requests a much larger tile
I was using TileCache, but I switched it off to debug this problem. If
TileCache generates larger tiles, will there still be clipped labels?
Just fewer clipped labels? I don't think this is a workable solution
for me, but if I have the time I'll try it.
Correct; there would be FEWER labels

I don't think that's possible if you're using tiles. Somewhere, some

Hey guys. Still no luck on this one, thought maybe I'd ask again.

Hey Stephen, nice to hear from you. :)
You should not need to download, build and install agg anymore.
Sounds good. I have uninstalled it; that is, deleted libagg.a and the

But that doesn't solve the build issue. I still get that linking error:

Good thinking, in case one somehow got placed somewhere.
Hey guys. Long time, no chat. :)
I'm trying to build 5.6.5 on Slackware/Slamd64. I have AGG installed (as

But it is throwing error :

It means what it says: one of your points has a invalid ordinate, so it
cannot be transformed.

Don't use MapServer's built-in TIFF support; GDAL's is a lot nicer
anyway. GDAL's even has BigTIFF if you build GDAL using its internal
