Ah. And, perhaps, affected with '--enable-debug' ? Im using that. So
just omitting '--enable-debug' should make the clang build succeed ? Or
am I (once again) missing the point here ?
No, not affected by --enable-debug.
And the 'add the patch <http://reviews.llvm.org/D12834?id=34645> "add
gcc abi_tag support'" part of the recipe is required independent of LO
--enable-dbgutil, only the "plus a little patch..." part can presumably
be ignored in the (implicit) --disable-dbgutil case.
(There may also be other ways how to make Clang on Fedora 23 work, like
overriding libstdc++'s _GLIBCXX_USE_CXX11_ABI setting, but I haven't
explored that.)
