[gdal-dev] Is it possible to switch warnings off?

[Joaquim Manuel Freire Luís]

Thanks Even e Mateusz

It is the same gdal lib in both cases. The only other one I have is sheltered in OSCeo4W.
And I had found where the messages are coming from but it's weird that they are printed in one case and not the other. I guess some internal setting that doesn't get set when called via Julia.

I'll explore the CPLPushErrorHandler()

Joaquim,

I suspect you are not testing with the same GDAL version with your gdalinfo shell invokation or within julia.

With the C API, you can shut down warnings and errors with

CPLPushErrorHandler(CPLQuietErrorHandler);

...

CPLPopErrorHandler();

You can install a custom error handler that filters only some category of events. See

Hi,

I have this strange case where some warnings come from don't know where.

>From a shell command (cmd but it doesn't matter) all fine

gdalinfo AQUA_MODIS.20020717T135006.L2.SST.nc
Driver: netCDF/Network Common Data Format
Files: AQUA_MODIS.20020717T135006.L2.SST.nc
Size is 512, 512
Metadata:
  /navigation_data/NC_GLOBAL#gringpointlatitude={28.923635,25.633446,42.81229,46.942131}
...


However, the same but this time called from Julia that wraps calls to
                              options = GDALInfoOptionsNew(options, C_NULL)
                              result = GDALInfo(ds.ptr, options)
                              GDALInfoOptionsFree(options)

I get these warnings

julia> println(gdalinfo("AQUA_MODIS.20020717T135006.L2.SST.nc"))
Warning 1: The dataset has several variables that could be identified as vector fields, but not all share the same primary dimension. Consequently they will be ignored.

...

Also get several of these in other commands

Warning 1: dimension #1 (pixels_per_line) is not a Longitude/X dimension.
Warning 1: dimension #0 (number_of_lines) is not a Latitude/Y dimension.


Is there anyway to shut up this warnings, or warnings in general?


Thanks

Joaquim
