#243 macos 10.7: fails to build

[rainbow]

Trying to build zint on macOS 10.7 I receive this strange error:

zint version: 2.10.0

Hi yes that is odd, if you delete that line and remove the reference to ar below in render() and its declaration in "barcodeitem.h", does it compile then?

I fixed the error blacklisting clang version lower than 500. Probably some incompatibility in c++ implementation.

you can close the ticket and thank you for the support.

Thanks for reporting back - I've removed references to AspectRatioMode anyway via [492d9a] as it's not used and unlikely to be used in the future - will close now...
