[Mapserver-users] when mapserv.exe runs it looks for avgridio.dll and aigridio.dll

[Tom H]

Hi group,

I ran filemon in order to see whether mapserv.exe was finding my epsg file correctly,
and it wasn't regardless of whether I defined a PROJ_LIB env variable. It was still 
looking in C:\PROJ\NAD, so I made a copy of the NAD folder there.

however, as filemon ran, it also looked for and did not find avgridio.dll and aigridio.dll
in the PATH, before giving up and then looking for the epsg file.

Are these files important?

it seems that these files are shipped with ArcGIS and/or arcView.

Cheers

T.
