Ahh, if I had just thought for a moment before firing off that last email I would have realized what happened in time. Autoconf is probably detecting that your main compiler is gcc and using that. So it sets some combination of automake conditionals to use gcc-style dependency tracking rules that are emitted inline into the Makefile. However your mpicc is using a different compiler under the hood and pgcc doesn't understand the "-MT target" format, among other things. So the dependency tracking rules that are used here are incorrect when compiling the MPI wrappers. I suspect you can get past this particular error while still using the wrappers for pgcc by passing "--disable-dependency-tracking" to Valgrind's configure. You may still want to pursue the GCC-based-MPI strategy for other reasons. -Dave ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable.
