If someone is interested in supplying a patch, I'm willing to consider applying it but we don't claim to support downward-compatible building for reasons like this. ![]() It may be possible to work around by adding AVAILABILITY macros at appropriate spots in C code or some such. There clearly was a specific problem introduced with the 10.12 SDK. If I find a cause/fix I'll open a new issue. and it has worked so far building on 10.9/10/11 for running on 10.6. You may also have success building on 10.12 by setting MACOSX_DEPLOYMENT_TARGET=10.9 and, if necessary, using the 10.9 SDK.) The simplest solution is to build on the lowest-supported release, e.g. ![]() I get the same error when building python on osx 10.12 + xcode 8 for 10.9+ and then running it on 10.11.Ĭhristoph, building on a newer OS X release for an older OS X release is tricky and out-of-scope for this closed issue. As you discovered, by not installing the clt, the build falls back to using the headers from an Xcode-supplied SDK which may be for a newer system than the one you are building on and thus might require dealing with missing OS features. To build cpython it is not necessary to download and install the full Xcode package, only the command line tools. That ensures that not only are the necessary build tools installed but also that the correct system header files are installed in /usr/include and elsewhere. It is a bit confusing but, in general these days, you should always install the current command line tools specific to the version of the Mac operating system you are running. Unintuitive though it may be, that seems to have done the trick. Try installing the command line tools via:Īnd doing a "make distclean" and then a complete configure and rebuild. There are various reports about Xcode 8.0 providing a 10.12 SDK which will include refs to symbols not available yet on 10.11. Searching for the error, I saw some suggestions elsewhere on the web that this might be a known problem, though I saw nothing here (just searched for _getentropy). I'm running Mac OS X 10.11.6, and upgraded to XCode 8.0 a few days ago.
