Dear Bob, Thanks for your reply. I already fix second issue. For first one, because I can’t execute edksetup.bat directly so I modify a little content of edksetup.bat, please see attachment and search “clouddai-test”. In addition, because there is no win32 bin file in I original edk2-master.zip, so I download it from Github, maybe this is key point. Waiting for your response. 寄件者: Feng, Bob C 傳送時間: 2019年7月1日 下午 06:10 收件者: Ni, Ray; ?,?? 副本: Justen, Jordan L; afish@apple.com; devel@edk2.groups.io 主旨: RE: May I become a contributor in EmulatorPkg ? For the second issue, you have to set the NASM_PREFIX to a path which ends with a slash. For the first one, could you provide the steps to reproduce it?

Dears, I live in Taiwan so please forgive my English pool. I download edk2 source code from Github recently and I encounter two build error when I build EmulatorPkg (I use Visual Studio 2017 ). First is in GenPcdDb.py, this error means parameter used to unpack is zero, please refer below : Second is in tools_def.txt, this error means there is missing slash before nasm.exe, please refer below : You can search “clouddai-test” in Attachment so that you will easy understand what I say. If I need submit more official document for become a contributor please let me know, or if my modification need obey some rule please also let me know, I am waiting your response
