On my Linux system, I cloned all the libraries and set the WORKSPACE and
PACKAGES_PATH env variables, sourced edksetup.sh and issued:
python3 edk2-platforms/Platform/Intel/build_bios.py --platform KabylakeRvp3
and got the following errors:
Traceback (most recent call last):
File "edk2-platforms/Platform/Intel/build_bios.py", line 1097, in <module>
main()
File "edk2-platforms/Platform/Intel/build_bios.py", line 1067, in main
platform_config = get_platform_config(arguments.platform, build_config)
File "edk2-platforms/Platform/Intel/build_bios.py", line 904, in
get_platform_config
path = platform_data.get(platform_name)
AttributeError: 'NoneType' object has no attribute 'get'
I don't know what I'm missing as to why this error pops up. How is this
done on a Linux system?
Did your build fail because of the VmgExitLib library not being specified?
If the platform includes the CpuExceptionHandlerLib or MpInitLib libraries
then it will now also need to include the VmgExitLib library.
I wish the build system could figure out that because the VmgExitLib
library is specified in the various CpuExceptionHandlerLib INF files and
the various MpInitLib INF files, it would automatically know to include it
in whatever uses those libraries. It doesn't seem right that you would
have to know and specify the library requirements of a library you are
including when the system could figure it out.
Thanks,
Tom
