[mvapich-discuss] MVAPICH Error

[OShea, Thomas T.]

Hello,

Actually we would like to be running 1.0-beta, but we are having trouble
compiling it. The configure script bombs out while trying to find the
size of 'bool' or something. 

The version we are currently using is the 0.9.8p3 with the patch you
gave me earlier applied. 

Thanks,
Tom

Hi Thomas, 

Are you seeing this behavior with MVAPICH2 0.9.8p2 with the patch
Gopal had sent to you on July 7th?

Have you tried MVAPICH2 0.9.8p3 or the latest release MVAPICH2
1.0-beta.  Do you see the same behavior with these two versions
also. In these versions we have applied a better solution to the
problem you had reported originally.

If you can let us know which version you are using currently, it will
help us to narrow down the problem further.

Best Regards, 

DK
