Hi! Currently, when a package needs C++11, we set CXXFLAGS+= -std=c++11 and hope for the best, i.e. that the platform compiler supports this. Shouldn't we rather add support to USE_LANGUAGES like this: USE_LANGUAGES+= c++11 and make bsd.pkg.mk set CXXFLAGS and request a good-enough compiler? Thomas
I agree. I run into this with a lot of scientific software and specifying a compiler in the pkg is kludgy. I assume people are aware of how FreeBSD ports handles this (e.g. USES+=compiler:c++11-lang). That system has some limitations, but at least it's compiler-agnostic and provides an interface that can remain consistent as the compiler landscape changes.
