Short answer: check out aclocal.m4 around line 869. We just use grep and sed to figure out what the petsc version is during configure. You could probably do the same for HYPRE_foo... Long answer: So, this is a really good question. Right now we just blanket-include petscconf in our Makefile as you have seen. (As of 3.0.x this changed again anyway to petscvariables...sigh) This has a couple potential drawbacks. One is that, if there are any variables set incorrectly in petscconf, for example $(AR) or some other system thing, we inherit those errors in our Makefile. The other problem is that we can't do anything very clever during configure since petsconf/variables/whatever only comes in at the Makefile stage. There are some potential workarounds for this, for example petsc used to have a 'make getlinklibs' or some such make target which would give you this stuff. A big problem with that was a 'make install' of PETSc didn't always include the Makefile, so we couldn't rely on it, etc. Someone with a lot of time could probably write a really good configure test (backwards compatible of course) which would grab any and all PETSc variables from the petscconf and related files. This way we would also not have to hard code the petsc link libraries as is done at line 488 of Make.common.in... -- John ------------------------------------------------------------------------------ Create and Deploy Rich Internet Apps outside the browser with Adobe(R)AIR(TM) software.
