[gdal-dev] Warning/Error Update?

[Andrew Bell]

Hi,

I don't know the history but I'm getting failures from warnings like this:

[ 75%] Building CXX object
frmts/raw/CMakeFiles/gdal_raw.dir/dipxdataset.cpp.obj
1169In file included from ../../alg/viewshed.cpp:36:
1170../../alg/viewshed.h: In constructor 'gdal::Viewshed::Viewshed(const
Options&)':
1171../../alg/viewshed.h:106:22: error: 'gdal::Viewshed::vFirstLineVal'
should be initialized in the member initialization list [-Werror=effc++]
1172 106 | CPL_DLL explicit Viewshed(const Options &opts)
1173 | ^~~~~~~~

This complaint is about a std::vector, whose initialization is
automatically addressed by its default constructor. The same kind of thing
happens with std::string. It's tedious (and IMO error-prone) to have to
initialize things that are already initialized.  This was recognized long
ago but perhaps never addressed:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=55837

Thoughts on turning off such checks as they're not sufficiently specific?
