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

[Andrey Prokopenko]

Hi,

 I've also bumped into it, and also cannot access bugzilla. Some search
 showed that one of the problems was that you actually need to add
 inline keyword like
    inline __attribute__((always_inline))

 But it seems that you cannot do that because you need at least C99 for
 inline keyword, but some configs in CMake or Makefile.am cause the
 code to be compiled -ansi, or -c90. The code in question seems to be
 in public domain, but I'm not sure about how easy is to modify it and
 what are the issues related to copyright. The easiest thing would be
 to require gcc < 4.7, or removed -ansi for compilation.
