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

Abhishek

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:

export PACKAGES_PATH=`pwd`/edk2-platforms/

build   -a AARCH64 -t GCC5 -p Platform/ARM/JunoPkg/ArmJuno.dsc -m Platform/ARM/JunoPkg/AcpiTables/AcpiTables.inf

Can anyone help understand this behavior?
