[cfe-dev] STL from libcxx looks for libc?

[salvatore benedetto]

I'm developing on a bare-metal cortex-m3 in C++ for fun and profit.

I recently decided to switch from GCC to clang.

I managed to set-up clang for cross-compiling for thumb2 (thanks to the
guys on llvm-dev mailing list).

Since I also needed to use the list container from STL, I installed libcxx.

I thought that as long as I give my own allocator, I shouldn't get anything
else more the what I use.

The compiler does find the library, but I get the following error

In file included from /home/emitrax/bin/llvm/lib/c++/v1/list:177:
In file included from /home/emitrax/bin/llvm/lib/c++/v1/algorithm:596:
/home/emitrax/bin/llvm/lib/c++/v1/cstdlib:96:9: error: no member named
'lldiv_t' in the global namespace
using ::lldiv_t;

etc...

I don't understand why it uses the cstdlib in the first place?

The symbol is declared in stdlib.h (that's what I get from man lldiv_t).
Is there some header inclusion missing?
