Hi Marshall
I’m just drawing your attention to this since I think you might have missed it in your lists inbox.
I probably should have just posted it here to begin with. Sorry.
Thanks
Hi Marshall
I thought you might want to know that libcxx has stopped being buildable with g++ as of 4.9.0.
The error output of the build is shown below.
The main error is:
c:/libcxx/include/string:1895:1: error: inlining failed in call to always_inline 'std::__1::basic_string<_CharT, _Traits,
_Allocator>::basic_string() [with _CharT = char; _Traits = std::__1::char_traits; _Allocator = std::__1::allocator<c
]': function body not available
Look for it in the full error output shown below.
If you need me to try out a patch, let me know. Sorry if I end up being a little slow in replying though, I don’t always follow so closely these days.
If I don’t hear anything in a day or two, I’ll post this on cfe-dev, assuming you’ve missed this email in the list deluge.
Thanks.
