Hi Even,
I have been trying to upgrade my compiler to resolve the GDAL
compilation issue but without success.
According to the documentation of unique_ptr,
|unique_ptr| may be constructed for an incomplete type
<https://en.cppreference.com/w/cpp/language/type-id.html#Incomplete_type>
|T|, such as to facilitate the use as a handle in the pImpl idiom
<https://en.cppreference.com/w/cpp/language/pimpl.html>. If the
default deleter is used, |T| must be complete at the point in code
where the deleter is invoked, which happens in the destructor, move
assignment operator, and |reset| member function of |unique_ptr|.
The error I encountered during the compilation shows that the deleter
of GDALRasterAttributeTable was invoked when the type was not complete:

Is there any other way to work around it?
Thanks,

Hi Even,
After resolving error on “GDALRasterAttributeTable” by adding
“gdal_rat.h” to gdal_priv.h, the compilation failed again.
The compiler on my machine was working fine with GDAL on the
master branch this early May. Could there be anything changed in
the GDAL master that caused the compilation failure?
yes, the addition of std::unique_ptr<GDALRasterAttributeTable>
m_poRAT{}; at line 3664 of gdal_priv.h
You should try to update to a more recent compiler.

My software is free, but my time generally not.
