Hi all,
I am running Mandrake Linux 7.0.2, Apache 1.3 and mapserv 3.3.010. I
have a .shp file in Lat/Lon coordinates and I've been trying to make it
work without success. Here follow the steps I performed:
1) I compiled the Mapserv with the Proj4 option successfully.
2) I tried to run my mapfile and an error ocurred.
3) I tried to run the sample with this Mapserv as a test and the same
error ocurred again:
Internal Server Error
"The server encountered an internal error or misconfiguration and was
unable to complete your request.
Please contact the server administrator, root at localhost and inform them
of the time the error occurred, and anything you might have done that
may have caused the error.
More information about this error may be available in the server error
log."
I didn´t find the "server error log" to see "more information".
I have to say that with the original Mapserv ( without Proj4 option) I
had no problems with the demo, but with my mapfile. The .gif image (
layer ) don't come up.
My questions are:
1) Can I work with Mapserv without Proj4 option or I must use the
statement PROJECTION and in consequence the Mapserv with Proj4 option ?
I red that if all data is in the same system then you don´t need the
Proj4 library at all.
2) Is the position of statement PROJECTION correct ?
Thanks in advance for any help.
