I'm trying to use this feature as described in various edk2 documents with zero success.
For example, in the INF spec 1.25, the following is defined for the protocols section :
The formats for entries in this section is:
gEfiProtocolCName [ | FeatureFlagExpression] ## Usage comment
When a FeatureFlagExpression is present, if the expression evaluates to TRUE, then the Protocal entry is valid. If the expression evaluates to FALSE, then the EDK II build tools must ignore the entry.
The following is an example of the [Protocols] section.
[Protocols]
gEfiDecompressProtocolGuid
gEfiLoadFileProtocolGuid
Does anyone have any examples showing the use of a FeatureFlagExpression ?
Thanks,.....Frank
