Ok, but it would make sense for the default configure to select the correct compile options that the build will run to completion.

So is that the reason why so many tests fail? I know of the codesigning requirement from actually using the debugger (or rather, answering the prompt for my password, which is the alternative). Where would I look for information on how to do this? It would seem logical for “make check” either to do it, or to report that it needs to be done.

Sorry, I confused things by talking about the OS version as opposed to the Darwin version. It’s Mac OS X 10.10.4 (Yosemite), Darwin 14.4.0, x86_64.
