Help re compiler options in Visual Studio

[simonwoodward]

I have fiddling with the compiler options in Visual studio to try and get some better diagnostics on my code. In particular I am wanting the compiler to check such things as:

- unused variable declarations

- unused COMMON blocks

- correct arguments in subroutine calls

Are their compiler options for these things?
Also, how do I restore the default compiler options for release/debug configurations?

Thanks

There is an option /warn:unused that will complain about unused declared variables. The option /warn:interface, which is on by default in a Debug configuration, will check argument consistency. There isn't an option that will check for unused COMMON blocks.

The /warn options are on the Diagnostics property page.

There is not an automated way of resetting project properties.

Thanks!

I have these options switched on, but I'm not getting any warnings. The code has a lot fo undeclared variables, and I have introduced a bug in the form of a missing argument in a subroutine call, but it's not reporting these. The build is producing no errors or warnings. And the *.diag file is empty, and the build log doesn't have any errors of warnings either.

This is the build log:

Oh - you're using 10.0! You willl also have to add /gen-interface under Command Line > Additional Options. This may not work well in that old release.

[simonwoodward]

What does that do? I added it and now I'm getting a fatal error (Code 1) on the first line of the code, which is a comment line.

[Steven_L_Intel1]

In version 10 (which is several years old), that would cause the creation of generated interfaces that the /warn:interface option would check. In the current version 12 (aka Intel Visual Fortran Composer XE 2011), /warn:interface implies /gen-interface.

There were many bugs related to this feature in earlier versions of the compiler, and you evidently hit one. Please obtain and use a current compiler version for best results.
