[cfe-dev] another try: lastest ubuntu 14.10 + gcc4.9.1 can't build clang

[Dennis Luehring]

i have found no solution to build clang svn under my ubuntu 14.04 x64 + 
gcc 4.9.2
still getting this error

/usr/bin/../lib/gcc/x86_64-linux-gnu/4.9/../../../../include/c++/4.9/cstddef:51:11: 

error:
        no member named 'max_align_t' in the global namespace
    using ::max_align_t;
          ~~^

today i tried a fresh ubuntu 14.10 x64 (lastest + updates) default: 
gcc.4.9.1 installation with clang svn 228566 in a virtual machine
the max_align_t problem does not occure but i was still not able to 
compile clang out of the box getting this error from make

i've built svn clang serveral times before on former ubuntu version 
without any problem
is there something still to fix in the svn version or should i use cmake 
or is the description
on http://clang.llvm.org/get_started.html only for release revisions?
