#1667: ExternalLibraries/MPI should report error messages ---------------------+------------------------------------------------------ Reporter: hinder | Owner: Type: defect | Status: new Priority: minor | Milestone: Component: Cactus | Version: development version Resolution: | Keywords: MPI ---------------------+------------------------------------------------------
Comment (by hinder):
In fact, the problem is likely that the Cactus configuration script mechanism by default swallows any unexpected errors. Unless you explicitly wrap code with begin/end error etc, the error message is lost. This is poor design, as it means you have to proactively anticipate any possible error and write code to capture it and format it. The Perl configuration script for MPI could maybe install some sort of error handling function which did this? But this is over-engineering the solution in the configure script. Cactus should handle this.
