Hi Linus,

The problem you are seeing appears to be with your development environment setup. It may be worth trying the settings described in ‘Laszlo's unkempt git guide for edk2 contributors and maintainers’ at https://github.com/tianocore/tianocore.github.io/wiki/Laszlo%27s-unkempt-git-guide-for-edk2-contributors-and-maintainers

Also, you could try setting the GCC_HOST_PREFIX environment variable to force the build system to use nmake.

set GCC_HOST_PREFIX=n

call %WORKSPACE%\edk2\edksetup.bat Reconfig

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

Dear Sir

After switching python 3.7. Still can’t work.

Has other error.

Thanks.

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
