Aditi Hilbert updated MYNEWT-499:
---------------------------------
Labels: Newt (was: )
> newt - APP_NAME value ambiguous for split images
> ------------------------------------------------
>
> Key: MYNEWT-499
> URL: https://issues.apache.org/jira/browse/MYNEWT-499
> Project: Mynewt
> Issue Type: Bug
> Security Level: Public(Viewable by anyone)
> Components: Newt
> Reporter: Christopher Collins
> Assignee: Sterling Hughes
> Priority: Major
> Labels: Newt
>
> Newt automatically creates a few macros on the command line when it builds a
> target:
> * {{ARCH_<arch-name>}}
> * {{ARCH_NAME="<arch-name>"}}
> * {{APP_<arch-name>}}
> * {{APP_NAME="<arch-name>"}}
> * {{BSP_<arch-name>}}
> * {{BSP_NAME="<arch-name>"}}
> There is a problem with the two APP defines. A split image consists of two
> apps (the "loader" and the "app"), so there is not a single correct value to
> specify during compilation.
> There are two issues here:
> * Code cannot rely on consistent values for the APP defines when it is part
> of a split image
> * Newt performs unnecessary compiling and linking operations for repeat
> builds of split targets. This is because the command-line invocation changes
> between builds, as the APP name is not consistent.
