[mapserver-users] Floating point exception

[Jeff McKenna]

Ciao Luca,

I am wondering also if you tried to access the PostGIS data through 
ogrinfo yet (to confirm there is no data issue).  Note that I'd 
recommend GDAL 3.4.2, PROJ 8.2.1 with MapServer-main.

  ogrinfo -ro PG:"user=xxxx password=xxxx host=127.0.0.1 port=5432 
dbname=xxxx" table -summary

Then, follow along the debugging document ( 
https://www.mapserver.org/optimization/debugging.html ) and add the 
following inside your MAP object in mapfile:

   CONFIG "CPL_DEBUG" "ON"
   CONFIG "CPL_TIMESTAMP" "ON"
   CONFIG "PROJ_DEBUG" "ON"

Then re-retry map2img with -all_debug 5, and look for the full SELECT 
query made to your database, and run that same query inside psql 
commandline.


-jeff
