Hi,
I have started using the Intel Fortran Compiler 11.1.038
What seems to be different from previous versions including the Beta releases of 11.1 is that the defult option seems to be -gen-inteface where for previous versions it was -nogen-interface
However, the man page and manuals for 11.1.038 still state -nogen-interface is the default.
I have done what I believe is a complete vanilla install.
Am I missing something?
regards
Mike Rezny

Yes, this was a deliberate change and I apologize for not noting it in the release notes. The separate option for -gen_interfaces was an artifact of the implementation and it caused many users to not get the checking they desired with -warn all. You can still disable generation with -nogen-interface if you want (but leave the checking enabled.)

Ok, thanks for this information. I know what is happening now. Thegen-interfaces behaviouris caused by -warn all which in 11.1.038 now seems to imply -gen-interfaces. This wasn't the case in previous versions.

Ok, I have the answer: I read the manual:
warn interfaces:
Tells the compiler to check the interfaces of all SUBROUTINEs called and FUNCTIONs invoked in your compilation against a set of interface blocks stored separately from the source being compiled.
The compiler generates a compile-time message if the interface used to invoke a routine does not match the interface defined in a .mod file external to the source (that is, in a .mod generated by option gen-interfaces as opposed to a .mod file USEd in the source). The compiler looks for these .mods in the current directory or in the directory specified by the include (-I) or -module option.
warn interfaces turns on the option gen-interfaces by default. You can explicitly turn it off with /gen-interfaces- on Windows and -no-gen-interfaces on Linux and Mac OS X.
This has changed since 11.0.074
warn interfacesTells the compiler to check the interfaces of all SUBROUTINEs called and FUNCTIONs invoked in your compilation against a set of interface blocks stored separately from the source being compiled.
