[MapServer-users] Verbosity of PROJ_DEBUG ON

[PE Lord]

I have Mapserver 7.6.2 compiled with proj 7.2.1 and gdal version (?). Sorry.

I have solved an PROJ issue on my current server. I have modified the PROJ_DATA (PROJ_LIB) sqlite database to handle properly my local projection, including a Canadian NTv2 grid transformation.

My ...proj/bin/projinfo, on my server seem to use the right Canadian nadgrid file (ca_nrc_NA83SCRS.tif).

Here my question, how to debug PROJ, through Mapserver will a high level of verbose?

Here my mapfile

CONFIG "CPL_DEBUG" "ON"
CONFIG "PROJ_DEBUG" "ON"
CONFIG "CPL_CURL_VERBOSE" "ON"
CONFIG "CPL_TIMESTAMP" "ON"
CONFIG "MS_ERRORFILE" "debug_proj.log"
