BTW, the "dataset" in previous message is created as
ds = Gdal.create("", driver=getdriver("MEM"), width=width, height=height,
nbands=size(GI,3), dtype=eltype(GI[1]))
https://github.com/GenericMappingTools/GMT.jl/blob/master/src/gdal_utils.jl#L530
where "G" is a 2D grid and size(GI,3) = 1
and the Gdal.create is defined in
https://github.com/GenericMappingTools/GMT.jl/blob/master/src/gdal.jl#L1194

Subject: [gdal-dev] GDAL 3.11 broke part of the Julia wrapper
Hi,
I'm afraid this one is not going to be easy, and I don't know how much help I
can provide to find the issue. The think is that
https://github.com/OSGeo/gdal/pull/12124 (which is a very big PR) broke my
Julia wrapper.
For example, this used to write a png image but now it errors with
julia> gdalwrite("lixo.png", mat2img(UInt8.([1 2 3; 4 5 6; 7 8 9])))
ERROR 1: Cannot guess driver for lixo.png
But maybe more concrete is this failure where it tries to extract info from a
gdal dataset (a pointer )
Gdal.GDALGetRasterYSize(dataset.ptr)
49
Gdal.GDALGetRasterCount(dataset.ptr)
1
Gdal.GDALDatasetGetLayerCount(dataset.ptr)
0
Here, first two are correct be the third is now wrong.
As I said above, I don't know how to provide more help on this and given the
amount of cpp files changed I have no idea what to try.
Joaquim
