Hi Bill,

I downloaded:


http://llvm.org/pre-releases/3.5/rc1/cfe.src-3.5rc1.src.tar.gz
http://llvm.org/pre-releases/3.5/rc1/llvm.src-3.5rc1.src.tar.gz
http://llvm.org/pre-releases/3.5/rc1/compiler-rt.src-3.5rc1.src.tar.gz

as well as the .sig files.  The signatures all checked.

I then unzipped and untarred all.  Then, noting there were symlinks:

~/dwnlds/llvm/3.5rc1 $ ls -ld llvm.src/tools/clang
lrwxrwxrwx   1 evansl         evansl         13 2014-07-22 21:19
llvm.src/tools/clang -> ../../cfe.src
~/dwnlds/llvm/3.5rc1 $ ls -ld llvm.src/projects/compiler-rt
lrwxrwxrwx   1 evansl         evansl         21 2014-07-22 21:19
llvm.src/projects/compiler-rt -> ../../compiler-rt.src
~/dwnlds/llvm/3.5rc1 $

I figured all I needed to do was the:

  Building Clang and Working with the Code
  On Unix-like Systems
  6. Build LLVM and Clang:

step as documented here:

  http://clang.llvm.org/get_started.html

However, when make was run, I got:

make[1]: Entering directory `/home/evansl/dwnlds/llvm/3.5rc1/build/lib/IR'

I've got the missing GLIBCXX; however, instead of being in /usr/lib,
it's in /usr/local/lib*:

/usr/local/lib64 $ strings libstdc++.so.6.0.20|grep GLIBCXX
GLIBCXX_3.4
GLIBCXX_3.4.1
GLIBCXX_3.4.2
GLIBCXX_3.4.3
GLIBCXX_3.4.4
GLIBCXX_3.4.5
GLIBCXX_3.4.6
GLIBCXX_3.4.7
GLIBCXX_3.4.8
GLIBCXX_3.4.9
GLIBCXX_3.4.10
GLIBCXX_3.4.11
GLIBCXX_3.4.12
GLIBCXX_3.4.13
GLIBCXX_3.4.14
GLIBCXX_3.4.15
GLIBCXX_3.4.16
GLIBCXX_3.4.17
GLIBCXX_3.4.18
GLIBCXX_3.4.19
GLIBCXX_3.4.20
GLIBCXX_DEBUG_MESSAGE_LENGTH
/usr/local/lib64 $

Is there something I should pass to the configure call to make the build
step look in the right place for GLIBCXX_3.4.20?

My operating system is ubuntu 14.04LTS:

TIA.
