Hi Daniel,
Symbols that start with "__" are reserved for system libraries. It appears
that you're not linking the C++ standard library or are linking with an
incompatible version. GDAL requires C++17 support.

Hi,
I was wondering if some of the RFCs should be placed somewhere other than
on the web site because they are obsolete/superseded. I think this would
make it easier to find relevant current information. Some of the RFCs are
marked as superseded, but from the standpoint of a web search, the more

Shawn,
Without details on your build configuration, it's not going to be easy to
figure out what's up. I wouldn't spend time looking at cmake-generated
makefiles. cmake works, so if you've having issues, it's because you
haven't properly told cmake where to find things in a way that generates

Hi David,
It's not clear what the issues are that you're having. Some specifics
as to the details of your problems would help.

My biggest question is why you would mix vector and raster operations
in the CLI.
And since we're taking on changing things, I would wonder why those
two parts of the codebase are commingled. Is there a strong reason not
to have an OGR project that does vector operations and a GDAL project
that do

There are many potential causes. Providing code and a backtrace would allow
someone else to look.

Hi,
Is a newly created raster band initialized to zero? If not, is there some
trivial way to perform such an initialization (this is a MEM driver raster,
if that matters).

Hi,
The documentation describes an application `gdal2xyz`, but I don't see one
built in my development environment. I also don't see anything in the
CMakeLists.txt that refers to it. Is it named something I'm not expecting?
Does it still exist?
Thanks,

I'm getting an error when flake8 runs as a pre-commit hook and it won't

The function in the subject returns a path to a utility on which to run a
test. But in the process, it tries to run the utility itself. This seems
strange. In my case, the test itself failed, but the code reported "Could

Hi,
I am aware that there isn't thread-safe raster access with the current GDAL
interface for various reasons. Given the state of processors, I was
wondering if it would be valuable to take a look at providing the ability
to do Raster I/O (at least reads) in a thread-safe way. This could be done

Hi,
Are there any issues with opening the same input multiple times as distinct

The documentation for GDALRasterBand::RasterIO says that it will convert

source code a bit I'm not sure I located the bit that does this conversion.

Hi,
I'm looking at the documentation for GDALRasterBand::RasterIO and it's
surprising that the names of the arguments aren't included in the function

arguments are described well below the function prototype, making it hard
