10.6.8 and ffmpeg

[Ken Cunningham]

Hi Richard

You have a lot of Xcode versions installed! Keeping them all straight must be a bit of a mind-bender.
perhaps select the most modern one (Xcode 4.2) and put the macOSX10.7.sdk in there?

that's a bit weird. that's a basic library.



In the 'full disclosure' category, my day-to-day 10.6.8 setup is as follows:

Xcode 4.2 is installed in /Developer and usually selected unless I'm testing something for Xcode 3.2.6, which I have installed in /Xcode3 but usually not selected
MacOSX10.7.sdk added to  /Developer/SDKs/MacOSX10.7.sdk (only used by libsdl2 that I know of)
LibcxxOnOlderSystems installed
default compiler set to macports-clang-3.7 (as per the libcxx instructions)


Best,

Ken
