[gdal-dev] Where to fins my own files

[Abel Pau]

Hi,
ok Even,

so, as my driver is not already online I have to do some changes at this part of the code, don’t I?

At this moment I have the file in the folder GDAL\data (my GDAL_DATA environment variable).
I call it like that.
aMMIDDBFFile=CPLFindFile("gdal", "MM_m_idofic.csv");

Do I have to move the file to somewhere? where?
Sorry cause it’s difficult for me imagine what to do.

Thanks

Hi,

actually the below question made me reconsider the current monolithic approach how data files are store in the source tree, to a cleaner one where each driver stores its potential data files in a specifc subdirectory and is responsible to install them (still in $prefix/share/gdal) :  https://github.com/OSGeo/gdal/pull/9087 . This improves relating data files to the driver that need them.

This has no impact on the installed artifacts. Note that when working with a development build, GDAL_DATA should now point to ${top_build_dir}/data, and no longer to ${top_source_dir}/data.

Hi,
Happy New 2024 to everyone who celebrates it!

I am programming a driver and in some point I need to read a file that contains some information (and it’s better to keep this in a file than in c code) about the Horizontal Reference System.
I have this file here: “GDAL\ogr\ogrsf_frmts\miramon”, but when coding I don’t know how to get to this folder.

There is any method to open a file (using VSIFOpenL(), for instance) in THIS specific directory? Can I use “GDAL\ogr\ogrsd_frmts\miramon” like that?

If not, where can I put this file to be found when executing the code? And how to write this path in the code?

Thanks in advance!!
