[gdal-dev] [EXTERNAL] [BULK] Re: Is there a way to load a custom driver without a declaration in gdal_frmts.h?

[Meyer, Jesse R. (GSFC-618.0)[SCIENCE SYSTEMS AND APPLICATIONS INC]]

Thanks, that looks promising.

Does GDAL automatically call `AutoLoadDrivers`?  If not, do team members need to force a call to that?

Hi Jesse,

https://gdal.org/api/gdaldriver_cpp.html#_CPPv4N17GDALDriverManager15AutoLoadDriversEv should answer your question.

Hi,



I know drivers can be built as plugins, but can they be detected / used by GDAL if they are not registered via gdal_frmts.h?  It doesn’t seem so.  Is this a C++ ABI restriction?  We’d like to provide members of our team an internal and custom gdal driver implementation without each of them needing a special GDAL build.



Best,

Jesse
