The rules do support an “Optional” keyword.  Does this rule format work before and after your INF change?

[Rule.Common.USER_DEFINED.ACPITABLE]
  FILE FREEFORM = $(NAMED_GUID) {
    RAW ACPI Optional               |.acpi
    RAW ASL Optional                |.aml
  }

Subject: Re: [edk2-devel] Question: module compilation failure with less number of files

I got an answer based on the other question I had posted.
I think "Rule" provided for given inf (using RuleOverride) forces certain files to be present:

[Rule.Common.USER_DEFINED.ACPITABLE]
  FILE FREEFORM = $(NAMED_GUID) {
    RAW ACPI               |.acpi
    RAW ASL                |.aml
  }

So, in this case, for given inf module, if either of .acpi or .aml file is not generated,
then below kind of error shows up:

: error F003: Output file for RAW section could not be found for Platform/ARM/JunoPkg/AcpiTables/AcpiTables.inf

Hi All,

I am trying to compile some ACPI tables, and I observed that
if I specify less minimal tables/asl as Sources for ACPI tables module INF file
(resulting in less size of overall module), compilation fails with below error:

build.py...
 : error F003: Output file for RAW section could not be found for Platform/ARM/JunoPkg/AcpiTables/AcpiTables.inf

To reproduce this issue,
1) Apply below patch (just keeping Fadt.c here as example;
Other ways: just keep ASL file after removing some objects to reduce file size; or keep combination of .c and .asl files - **as long as these files are small**):

2) Now compile the module:

Can anyone help understand this behavior?
