[mvapich-discuss] Linking problems

[J R Jones]

Hi

This is the output at present.  I'll run it again with the -show option
shortly when the machine is less busy..  I also couldn't see anything
explicit in the scripts so I don't know if perhaps it is something to do
with our Intel Compiler.  I've built GotoBLAS2 with the Intel compilers
for 64-bit with the default options, and am now trying to build HPL-2.0
using the same compilers, the built GotoBLAS2 and MVAPICH2.  I am aware
however that this is using version 1.2 as supplied by our cluster vendor
so I don't know if this is something that has been fixed.
