error: use of unknown builtin '__builtin_bswap16'

it built on 10.6.8, so forcing a newer clang on the several failing systems should do it.

çkencu, please let me know which is the proper route for installing clang, as i have installed only xcode 4.6.3 for mountain lion 10.8; xcode 5.0 and xcode 5.0.2 is no longer downloadable it seems on the applesite (gives me "forbidden") and xcode 5.1.1 requires 10.8.4.

according to <https://packages.macports.org/libsdl2/> everything from 10.11 thru 10.15 failed.

so we need to blacklist the clangs up to what is in 10.15, and that should do it.

Josh is around. Probably already working on it.

if you do this, it should work until he fixes it:

sudo port clean libsdl2
sudo port install clang-9.0
sudo port install libsdl2 configure.compiler=macports-clang-9.0
