The following bug has been logged on the website:
Bug reference: 16686
Logged by: Yorick de Wid
Email address: yorick17@outlook.com
PostgreSQL version: 13.0
Operating system: Ubuntu 20.04
Description:
Postgres C++ extensions can use STL functions and methods that (indirectly)
depend on <locale>. GNU GCC implements <locale> via `libintl.h`.
This causes a build conflict if postgres is not build with NLS support. The
prototype definitions of `libintl.h` conflict with defined placeholders in
the `c.h`.
There is no flag to disable `libintl.h` in the GCC implementation of the
STL.
When building anything that utilizes the C++ STL, one does not have the
guarantee it will compile, unless postgres was build with NLS support.
This does not necessarily constitutes a bug, however another warning in the
manual about C++ extensions could be sufficient.
Cheers,
