Thanks, that looks promising.

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

GDALAllRegister() which is normally called by all standard code using GDAL calls it: https://github.com/OSGeo/gdal/blob/54890592b410d95a59b4b07c0b499ca383005514/frmts/gdalallregister.cpp#L319

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
