The following header is included in order to provide one instance of the symbol vcos_deprecated_code.
|
||
|
|
Any other inclusions of this header (or "vcos_deprecated_code.inc" for assembly language) will cause the linker to warn
|
||
|
|
about multiple definitions of vcos_deprecated_code.
|
||
|
|
The idea is to include this header file for the source files which are deprecated.
|
||
|
|
Therefore the above warnning in a build indicates that the build is using deprecated code!
|
||
|
|
Contact the person named in the accompanying comment for advice - do not remove the inclusion.
