[Libmesh-users] Compilation error in SVN head

[David K. <dkn...@se...>]

I just svn up'd and ./configure'd and I'm getting the compilation error:

Compiling C++ (in debug mode) src/base/dof_map.C...
In file included from 
/home/dknez/software/libmesh/include/base/dof_map.h:39:0,
from src/base/dof_map.C:30:
/home/dknez/software/libmesh/include/parallel/threads_allocators.h:103:13: 
error: ‘ptrdiff_t’ does not name a type
make: *** [src/base/dof_map.x86_64-unknown-linux-gnu.dbg.o] Error 1

Seems like a strange thing for the compiler to complain about, no? I'm 
using gcc 4.6.1:
gcc (Ubuntu/Linaro 4.6.1-9ubuntu3) 4.6.1
