Charm++ parallel programming system

[Phil Miller <mille121 AT illinois.edu>]

That is a warning message (indicated by the "(W)"), and occurs in a system header provided by IBM over which we have no control.

Did Charm++ build successfully for you on this system? If not, please quote us the actual error message(s) for the last object that failed to compile.

As a side note, if you want to obtain the best performance from NAMD or other Charm++ applications on Bluegene/P and most other systems, it is preferable to use a native network layer rather than one layered over MPI. In your case, that would be named simply "bluegenep", rather than "mpi-bluegenep"

Dear Sir/Madam,
On our BlueGene/P machine,we are trying to compile NAMD version 2.9, and at the first step to compile CHARM++.

We use the command line as:
./build charm++ mpi-bluegenep xlc --incdir /bgsys/drivers/ppcfloor/comm/fast/include --libdir /bgsys/drivers/ppcfloor/comm/fast/lib -O2 -optimize -DCMK_OPTIMIZE -Q -qarch=450 -qtune=450

During the compiling, we met such error message:
/bgsys/drivers/ppcfloor/comm/include/dcmf.h", line 244.7: 1540-1608 (W) An anonymous union should only define non-static data members.

could you help to figure out such error? thanks.
