Hi, i cannot reproduce this in my environment, this should be something specific to yours can you please run grep HWLOC_SIZEOF_UNSIGNED_INT src/pm/hydra/tools/topo/hwloc/hwloc/include/private/autogen/config.h this should return #define HWLOC_SIZEOF_UNSIGNED_INT 4 then in src/pm/hydra/tools/topo/hwloc/hwloc/include/private/misc.h, at line 23, add the following four lines #define STRINGIFY(s) XSTRINGIFY(s) #define XSTRINGIFY(s) #s #pragma message ("HWLOC_SIZEOF_UNSIGNED_INT " STRINGIFY(HWLOC_SIZEOF_UNSIGNED_INT)) #pragma message ("HWLOC_BITS_PER_INT " STRINGIFY(HWLOC_BITS_PER_INT)) and then recompile : cd src/pm/hydra/tools/topo/hwloc/hwloc/src make traversal.o this should return /.../src/pm/hydra/tools/topo/hwloc/hwloc/include/private/misc.h:25: note: #pragma message: HWLOC_SIZEOF_UNSIGNED_INT 4 /.../src/pm/hydra/tools/topo/hwloc/hwloc/include/private/misc.h:26: note: #pragma message: HWLOC_BITS_PER_INT (4 * 8) Cheers, Gilles On 2014/04/06 21:53, 童伟 wrote:

I tried with gcc, got errors during make, too.
