LIN7-2784 : toolchain-wrappers are deprecated but not documented as such

Created: Jan 28, 2015    Updated: Sep 8, 2018

Fix Version:
Severity: Standard
Applicable for: Wind River Linux 7
Component/s: Build & Config, Documentation, Toolchain


As of WRL 7 the toolchain wrappers, enabled via the --with-template=feature/toolchain-wrappers option, are deprecated. However, there is nothing in the User Guide or the layer README to inform the customers of this.

It would be useful to have these documents updated.
If possible, it would also be good if a warning could be displayed when the template is enabled.
