llvm dev - Nov 2013 - [LLVMdev] LLVM compilation problem

I am using gcc 3.4.6 to build LLVM, and am encountering overloaded/ambiguous
errors in several files...

% gcc -v
Reading specs from /usr/lib/gcc/i386-redhat-linux/3.4.6/specs
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man
--infodir=/usr/share/info --enable-shared --enable-threads=posix
--disable-checking --with-system-zlib --enable-__cxa_atexit
--disable-libunwind-exceptions --enable-java-awt=gtk --host=i386-redhat-linux
Thread model: posix
gcc version 3.4.6 20060404 (Red Hat 3.4.6-11)

The errors I am seeing during compiler w/ gmake are all the same (more or
less)...

% ../llvm/configure  --prefix=$HOME/local  --exec-prefix=$HOME/local/$MACHTYPE
...
% gmake ENABLE_OPTIMIZED=0
...

I can't say anything about your specific errors, but there are
definite plans that LLVM 3.4 will require GCC 4.7.x to compile (since
it'll use C++11 features). Regardless, 3.4 is ancient. Unless you're
in a particularly bizarre time-warp I'd suggest using a more recent
host compiler.

If you *are* in such a time-warp, your best bet is probably just
working backwards through the versions of LLVM until you find one that
compiles. Or reprioritising.

Cheers.

Tim.

Sorry, just in case this gives anyone a heart attack, I obviously
meant 3.5 (which will be released in spring 2014, and so subversion
trunk might start needing C++11 Any Time Now).
