[mpich-discuss] misc.h(28): catastrophic error: #error directive: "unknown size forunsigned int."

[Gilles Gouaillardet]

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
