1st of all, thanks for the HeadsUp !!!
OK, I'm running into this problem w/ php <= 8.2 where it fails w/ -at
least- bcmath.
Now, what is the most correct way of specifying a C++ version ? When
looking at the Portfiles, I can see at least 4 (four) diffenrent ways !
Examples
configure.cxxflags-append -std=c++11
configure.cflags-append -std=c++11
configure.ldflags-append -std=gnu11
configure.env CXXFLAGS=-std=c++1z
Also, the C++ standard is issued everry 3rd year, so we've got
c++11 ; c++14 ; c++17 ; c++20
Which one is recommended for php ?
Furthermore, should I report this upstream ?
