[Xquartz-dev] Python2.7 build failure using fink and XQuartz 2.7.10_beta2 (xorg-server 1.18.3)

[Viv Kendon]

I’m told by the fink experts that the build failure I’m seeing may be due to an incorrectly included library in this xquartz beta (2.7.10_beta2):

comments from the package maintainer:

"I think it must be the XQuartz beta. It seems to have an inappropriate library, /opt/X11/lib/asan/libclang_rt.asan_osx_dynamic.dylib, which is actually part of clang’s address sanitizer debugging tool. It must have been included by mistake and/or they left debugging code in that is built for a newer OS. It’s looking for a symbol called “__os_trace_with_buffer” in libSystem but that symbol doesn’t exist as of 10.11. I suspect it’s from 10.12. So this looks like a buggy XQuartz release. Python builds fine for me on 10.11 with non-beta XQuartz.”

I’m on 10.9.5 with Xcode.app: 6.2
Xcode command-line tools: 6.2.0.0.1.1424975374
and a case-sensitive file system.

many thanks,
