I am trying to compile maloader <https://github.com/shinh/maloader> using
clang-3.4 on Ubuntu 12.04 (precise) amd64. The clang-3.4 were installed by apt
as instructed <http://llvm.org/apt/>. Here is my building process.

$ cd maloader

I don't think this is related to the upstream maloader source, since map.h
should be in path. 

I have installed gcc-4.8, which has the correspondent header at
/usr/include/c++/4.8/profile/map.h

But when I modified the CFLAGS from
GCCFLAGS+=-g -Iinclude -Wall -MMD -fno-omit-frame-pointer -O $(GCC_EXTRA_FLAGS)
to
GCCFLAGS+=-g -Iinclude -I/usr/include/c++/4.8
-I/usr/include/x86_64-linux-gnu/c++/4.8 -Wall -MMD -fno-omit-frame-pointer -O
$(GCC_EXTRA_FLAGS)

It cannot be linked:
