[LLVMdev] Building llvm using non-system gcc/binutils

[john blair]

Hi Eli,

I tried to build llvm with gcc-4.4.3 and binutils-2.20.1. This time it failed with 
/build/toolchain/src/llvm-2.7/objdir/Release/bin/tblgen: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by /build/toolchain/src/llvm-2.7/objdir/Release/bin/tblgen)
make[1]: *** [/build/toolchain/src/llvm-2.7/objdir/lib/VMCore/Release/Intrinsics.gen.tmp] Error 1
make[1]: Leaving directory `/build/toolchain/src/llvm-2.7/objdir/lib/VMCore'
make: *** [all] Error 1

Hmm, it shouldn't be looking for libstdc++ in /usr/lib
