+
+
+ The blacklist (blacklist) class prevents
+ the OpenEmbedded build system from building specific recipes
+ (blacklists them).
+ To use this class, inherit the class globally and set
+ PNBLACKLIST for each recipe you wish to blacklist.
+ Specify the PN
+ value as a variable flag (varflag) and provide a reason, which is
+ reported, if the package is requested to be built as the value.
+ For example, if you want to blacklist a recipe called "exoticware",
+ you add the following to your local.conf
+ or distribution configuration:
+
+ INHERIT += "blacklist"
+ PNBLACKLIST[exoticware] = "Not supported by our organization."
