wxWidgets-3.2: builds on 10.7 but requires `--with-macosx-sdk` set to 10.8 SDK

According to the official website, wxWidgets-3.2 will run on 10.7+, but when building on 10.7, it fails due to 10.8 - specific SDK features (log attached).

Passing in the path to the 10.8 SDK on 10.7 does fix the build.

I thought ${developer_dir}/SDKs/MacOSX10.8.sdk should be the path, but it turns out that is not correct on 10.7 at least. The following worked:

--with-macosx-sdk=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk \
--with-macosx-version-min=${macosx_deployment_target} \

Worth noting I think that the MacOSX10.8.sdk is I believe pre-installed in the Xcode for 10.7, so nothing actually needs to be physically added.

Thanks a lot. I thought 10.7 was sufficient, but I didn't test the latest version. Yes, 10.8 is preinstalled in the last couple of Xcode versions shipped for 10.7 (only the earlier versions included the SDK for 10.6). I thought we have a more straightforward way to specify the SDK than to hardcode the full path, but maybe I'm wrong.

Are you willing to commit the patch yourself?

Just for fun I would check whether compiling against 10.8 is also needed for dependent port, but I assume/hope not.

For interest, wxWidgets-3.2 also builds on 10.6.8 against the 10.8 SDK with some minor tweaking of the install names afterwards. I generally only use 10.6.8 / libc++ , so I haven't tested other builds as yet.

Not extensively tested just yet, but perhaps this might be useful.
