Upcoming conda package changes may affect compiler detection.

[Former user]

I am not sure how much of an effect it is. But I was notified of this document

https://docs.google.com/document/d/103QY204eD82fJzpT7eXy_rV2bKwe6Hx5uAnkMg_xwkI/edit?ts=59d3dfc1#heading=h.p4o4zy619i0w

They basically started to rely on the environment variables to specify a cross compilation compiler for compiling 'many-linux' binaries on the native platform.

We currently propagate the compiler settings reported by mpi4py to our Python extension modules.

We currently propagate the compiler settings reported by mpi4py to our Python extension modules. What do you mean? What compiler settings? Could you point me to a code snippet doing that?

These flags are passed down to the fft C library.

I think most of these will work out just fine. I was able to compile this library after the mpich2 package is updated to properly use the cross-compilers. To mpi4py, nothing has changed at all.

I think we are safe for the most part.

[Lisandro Dalcin]

Yes, indeed, you should be safe.
