A small correction: if you use our linux compilers, then the software you build will link to glibc 2.12 and will run on any Linux with glibc 2.12 and above. BT

A small correction: if you use our linux compilers, then the software you build will link to glibc 2.12 and will run on any Linux with glibc 2.12 and above. BTW we also have our own macOS clang 4.0.1 based compilers and they both run on and generate software for macOS 10.9 and above. You need to provide your own macOS 10.9 SDK and point CONDA_BUILD_SYSROOT to where you unpack it (or use one you got with Xcode and risk lower backwards compatibility).
