With two exceptions, I have successfully compiled what I believe to be all of the llvm toolchain packages on my Mac.
One exception is lang/compiler-rt; for that I needed the patch the PLIST.Darwin file as below. Is that ok to commit or is there some reason this is incorrect?
The second exception is devel/lldb, which had the following error during compilation:
[ 36%] Building CXX object source/Plugins/ExpressionParser/Clang/CMakeFiles/lldbPluginExpressionParserClang.dir/ClangHost.cpp.o
/Volumes/NetBSD-boost/NetBSD/pkgsrc/pkgsrc-cvs/devel/lldb/work/lldb-7.0.1.src/source/Plugins/ExpressionParser/Clang/ClangHost.cpp:78:17: error: no matching function for call to 'next'
auto parent = std::next(rev_it);
^~~~~~~~~
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1/iterator:521:25: note: candidate template ignored: disabled by 'enable_if' [with _ForwardIter = llvm::sys::path::reverse_iterator]
typename enable_if<__is_forward_iterator<_ForwardIter>::value>::type* = 0)
^
The requirement for std::next() is that the first argument be a LegacyForwardIterator (until c++17) or a LegacyInputIterator (since c++17). In this case, it is a reverse iterator as indicated in the error. Clearly, the type traits in use claim that a reverse iterator does not meet the requirement, so the overload for std::next() is disabled because of SFINAE.
So, what should be done to make this compile on a Mac? The compiler in use is AppleClang 8.0.0.8000042.
Thanks for your help.
Cheers,
Brook
