[Trilinos-Users] Aztecoo question

[Heroux, Michael A]

Jason,

This statement is from f2c-generated code.  I am not sure why it is part of the boilerplate, except maybe to protect against expansion of variable names in the generated C code to the macro definition.  I think the right way to shut this off is to add -DSkip_f2c_Undefs to CFLAGS.

We should be able to safely remove the entire section of #undef's in future versions.  For now you could easily just comment out the offending line.

I'm compiling aztecoo using the cray compiler and I came across an error when compiling az_c_reorder.c(its in the src directory in aztecoo):

/trilinos-10.0-Source/packages/aztecoo/src> cc az_c_reorder.c
/opt/cray/xt-asyncpe/3.5.17/bin/cc: INFO: linux target is being used

  An attempt is made to undefine a predefined macro.

  #undef unix
         ^

I wonder if I can just comment out this line? It doesn't seem to affect anything else in the code.
