"::malloc not found"

Clang Frontend
#1

Hi,

I can compile libmemcached-1.0.5 just fine with gcc/g++ (on Ubuntu 12.04). But when I try with Clang 3.0 I get:

   CXX libmemcached/csl/libmemcached_libmemcached_la-context.lo
In file included from libmemcached/csl/context.cc:38:
In file included from ./libmemcached/csl/common.h:40:
In file included from ./libmemcached/common.h:49:
/usr/include/c++/4.6/cstdlib:118:11: error: no member named 'malloc' in the global namespace
   using ::malloc;
         ~~^
/usr/include/c++/4.6/cstdlib:126:11: error: no member named 'realloc' in the global namespace
   using ::realloc;
         ~~^

Any pointers on whether this is a Clang or libmemcached problem? It compiles just fine with gcc after all...

Best,
Martin

glibc headers can be strange and gcc headers can be strange, so
"compiles fine with gcc" is not a very useful metric. I suggest you
start by using adding -save-temps and check when malloc/realloc are
defined. One item to look for: stray extern "C" blocks. GCC seems to
implicitly switch back to C++ mode for the C++ system headers, Clang
doesn't.
