Hi Linus,

It looks like Python2.7 is not working with the EDK2 build system on Windows (at least for Arm builds). Can you try using Python 3.7 instead?

I am using Python 3.7.3 and the build is working. Please let me know if switching to Python 3.7 does not work.

Regards,

Sami Mujawar

Dear Sir

I’ve followed the attachment try to build UEFI on ARM platform.

But when I ran the below command.

build -a AARCH64 -t GCC5 -p Platform\ARM\VExpressPkg\ArmVExpress-FVP-AArch64.dsc -b DEBUG

It shows

Build fail.

Then

I’ve tried.

build -a AARCH64 -t GCC5 -p Platform\ARM\VExpressPkg\ArmVExpress-FVP-AArch64.dsc -b DEBUG  clean

It shows
