LLVM 19 compilation issue

[lixun910]

Dear maintainer,

Please see the problems shown on
https://cran.r-project.org/web/checks/check_results_rgeoda.html.

Specifically, please see the clang19 additional issues.

These show compilation problems using the compilers from LLVM 19,
finally released yesterday. The results are for Fedora 36 (see
https://www.stats.ox.ac.uk/pub/bdr/clang19/README.txt) and can
conveniently be reproduced using the clang-19 and flang-19 packages in
Debian unstable.

Can you please fix "as necessary"?

Please correct before 2024-10-09 to safely retain your package on CRAN.

Best wishes,
The CRAN Team

It looks like not a bug of rgeoda, but a bug when #include <boost/geometry.hpp> from Boost::geometry. Did some research, and it looks like a known issue of Boost for clang19, llvm/llvm-project#101079, and some fixes are in progress: eddelbuettel/bh#101

The fix has been merged into develop branch in boost::qvm boostorg/qvm@106d411

However, if -Wno-error=missing-template-arg-list-after-template-kw can be used as a workaround, it would be great that CRAN can accept it as a solution. See CRAN accepts -Wno-error=enum-constexpr-conversion for c++17:
