[petsc-users] PETSc with Julia Binary Builder

[Patrick Sanan]

As you mention in [4], the proximate cause of the configure failure is this link error [8]:

Naively, that looks like a problem to be resolved at the level of the C++ compiler and MPI.

Unless there are wrinkles of this build process that I don't understand (likely), this [6] looks non-standard to me:

	includedir="${prefix}/include"
	...
	./configure --prefix=${prefix} \
		...
		-with-mpi-include="${includedir}" \
		...


Is it possible to configure using  --with-mpi-dir, instead of the separate --with-mpi-include and --with-mpi-lib commands? 


As an aside, maybe Satish can say more, but I'm not sure if it's advisable to override variables in the make command [7].

One of the first things to get going is to use Julia's binary builder [1] to wrap more scalar, real, and int type builds of the PETSc library; the current distribution is just Real, double, Int32. I've been working on a PR for this [2] but have been running into some build issues on some architectures [3].

So a (desktop) user can get MPI, PETSc, etc. without the headache of having to build anything from scratch; obviously on clusters you would still want to use system MPIs and what not.
