[LLVMdev] make error building llvm/clang 3.2 on Linux

Tue Feb 26 14:32:32 PST 2013

Michael,

This behavior repeats itself on Debian Linux when I update GCC 4.7.2 to 
anything above the current pathways of the Sid branch release of 
GCC/Libstdc++ collection.

I've tested it twice with their latest updates for the 4.7.2 branch in 
Experimental and nothing on there end changes and from prior issues with 
this someone either has to update the pathways for these directory 
structures in LLVM/Clang or don't even bother first building LLVM/Clang 
with anything newer than

gcc-4.7.2-5 and all that includes with gcc-4.7-base, etc.

This is fine with me because I'd rather let Debian muck with all the 
llvm-toolchain-3.2 attempts they continue to try:

http://qa.debian.org/developer.php?login=pkg-llvm-team@lists.alioth.debian.org

before I update any release from them. I've just stuck with 4.7.2-5 and 
building trunk once and then configuring with cmake the necessary paths 
in the newest trunk to make everything build under /usr/local
