Hi, Thanks for your help. I am to build base tools and able to generate bin files. "Build" command is generated. Later, I am trying to build "EmulatorPkg". And running into VfrCompile error. 'VfrCompile' is not recognized as an internal or external command, operable program or batch file. NMAKE : fatal error U1077: '"VfrCompile' : return code '0x1' Stop. 'VfrCompile' is not recognized as an internal or external command, operable program or batch file. I can see VfrCompile.exe generated in "BaseTools". Attached build log for "Emulator Pkg". I tried checking the Env Paths .

If you look closely you will see in the CI process this required a change where stuart_setup is run before calling edk2toolsbuild.py. https://github.com/tianocore/edk2/commit/e1fbff3ded87704fb0086f9b5fb368080eb4db51#diff-6973939bf9ad6f6a3082d99ce3b32ff1 If you are using "stuart" to build then that is the suggested path as stuar_setup will init your submodules listed in the RequiredSubmodules (https://github.com/tianocore/edk2/blob/master/.pytool/CISettings.py#L136). Given that the edk2 project and ecosystem has numerous ways to setup your environment and build, you can also just make sure your workspace is complete prior to running Edk2ToolsBuild.py. In this case you only need to run "git submodule update --init" I just did this and it works fine with VS2019. Jim, Just as fyi as I know there are lots of reasons for toolchain selection. I believe the Visual studio build tools are available free of charge (not the IDE but the compilers). Directions here. https://microsoft.github.io/mu/CodeDevelopment/prerequisites/#visual-studio-2019-preferred Thanks Sean From: devel@edk2.groups.io > On Behalf Of Navdeeppal.Singh via groups.io Sent: Thursday, April 23, 2020 9:14 AM To: Bret Barkelew >; devel@edk2.groups.io Subject: Re: [EXTERNAL] [edk2-devel] EDK2 environment setup Hi Bret, Yes PIP requirements are up to date.

"pip install -upgrade -r pip-requirements.txt"? That's the first thing I would check. Otherwise, happy to look at the problem with you. - Bret From: NAVDEEPPAL_SINGH via groups.io Sent: Thursday, April 23, 2020 6:05 AM To: devel@edk2.groups.io Subject: [EXTERNAL] [edk2-devel] EDK2 environment setup I am trying to setup EDK2 environment setup from Tianocore/EDK2.
