What does the -Vaxlib option do?

[john_low]

I have noticed this in some makefiles i am using. It appears to have something to do MPI or linking routines written in C with Fortran routines. What does -Vaxlib ifort option do?

-Vaxlib is an older option for the version 9.0 and older compilers and no longer exists. It linked in a compatibility library to provide routines supported on Vax Fortran amongst other routines. It really had nothing to do with MPI or C, although you may find some web search engine hits on these topics. It really was needed to bring in functions like GETARG and IARGC.

These routines are folded into the base libraries (libifcore) and thus -Vaxlib is no longer needed.

What version of the Intel Fortran compiler no longer needs -Vaxlib option? ifort 9.1 and later? 10.0 and later?

I'm not sure it was needed as of 8.0 - it was certainly misnamed.
