#43939: libpng: pngconf.h:366:52: error: token is not a valid binary operator in a preprocessor subexpression -------------------------+-------------------------- Reporter: macports@… | Owner: ryandesign@… Type: defect | Status: assigned Priority: Normal | Milestone: Component: ports | Version: 2.3.0 Resolution: | Keywords: Port: libpng | -------------------------+-------------------------- Comment (by ryandesign@…): Yes, Xcode 3.2.6 is available for Snow Leopard, and you should upgrade to that version. See https://guide.macports.org/#installing.xcode.snowleopard I guess `__has_attribute` got added to clang after version 1.5, but by version 1.7. I've just installed Xcode 3.2 which comes with clang 1.0 and I'll see if I can replicate the problem there. -- Ticket URL: <https://trac.macports.org/ticket/43939#comment:14> MacPorts <http://www.macports.org/> Ports system for OS X
