[Trilinos-Users] Fwd: Spurious warnings in Trilinos debug builds

[Evans, Thomas M.]

This isn’t formally a bug, but in commit 9bc4d894 the following messages got added to DEBUG builds:

Using 1 processors

These get output at runtime, regardless if the current application actually instantiates any Trilinos objects or not.  All that is required is for one of the loaded libraries (or its dependencies) to have these symbols.  Can these be turned off (without doing non-debug)? It seems somewhat invasive for a downstream library to output to stderr when the application isn’t even using any of these services.
