Hello,

I am trying to change my top-level FDF file layout by conditionally including an FDF depending on a build time define being passed or not. The behavior I am seeing is as follows.

  1. I am passing the build time define and the included fdf.inc file gets included.
  2. I am not passing the build time define and the included fdf.inc file still gets included apparently.
    1. However, there is a strange behavior which is that in the conditional block if I have anything else other than the !include statement, it gets ignored.
    2. But if there is a !include statement inside a conditional (which should fail) the include statement is still processed.
Conditional statement in top-level fdf is:

!ifdef $(BUILD_PLATFORM_XYZ)
  !include Platform/NVIDIA/XYZ.fdf.inc
!endif

When we do not pass in -D BUILD_PLATFORM_XYZ during build, Platform/NVIDIA/XYZ.fdf.inc file should not be included as it could be totally absent as well. However, the build system tries to include the file and fails with the following log.

GenFds.FdfParser.Warning: The include file does not exist under below directories:
<Here it lists the root diectories included in the build>.
<Here it lists the line and column number of top level fdf file which has include statement for Platform/NVIDIA/XYZ.fdf.inc but under a conditional as mentioned above.

Any help getting around this if you think I am checking for the conditional incorrectly or checking the build script for a potential bug would be highly appreciated.

Thanks
