[Trilinos-Users] gcc 4.7 compile error for zoltan package

Mon Aug 27 09:44:44 MDT 2012

Andre,

The flag -ansi should not be added to the compile line in a release of Trilinos (only in the development mode which should not be the default).  Can you cd into the directory and type 'make VERBOSE=1 <the target>' and see what compile options it is showing?  What is your configure line?  What Trilinos release version is this?

Otherwise, I believe that Trilinos does not assume the C99 standard, only the C89/C90 standard, so such code would have to be changed or be explicitly dependent on a C99 enable flag or something.  Trilinos needs a more clear policy on assumed C standards and a clear way to allow some code to require (or be conditionally enabled) for the C99 standard.
