Hello,
The following compilation condition in OpenPlatformPkg\Platforms\ARM\Juno\AcpiTables\Fadt.aslc #if ARM_JUNO_ACPI_5_0
causes the GCC error listed below k:\edk2\OpenPlatformPkg\Platforms\ARM\Juno\AcpiTables\Fadt.aslc:76:22: error: #if with no expression #if ARM_JUNO_ACPI_5_0 ^ when ARM_JUNO_ACPI_5_0 macro is defined in edk2\ArmPlatformPkg\ArmJunoPkg\Include\ArmPltaform.h: #define ARM_JUNO_ACPI_5_0
To fix the bug #if ARM_JUNO_ACPI_5_0 should be replaced with #ifdef ARM_JUNO_ACPI_5_0 (also see the previous usage on line #20 in the same file)
Alexei.
