Questions occurs in the EDK2 environment building process

[ZBCMars]

Hi, Im a beginner in it and faced some problems when I tried to build the environment.

My config:

• Ubuntu 20.04
• GCC 9.4.0
• nasm 2.14.02
• Python 3.8.10

And I followed this flow:

git clone https://github.com/tianocore/edk2.git
cd edk2
git submodule update --init
make -C BaseTools
export EDK_TOOLS_PATH=$HOME/src/edk2/BaseTools
. edksetup.sh BaseTools

I also modified 2 places in ～/src/edk2/Conf/target.txt:

• line 20: ACTIVE_PLATFORM       = MdeModulePkg/MdeModulePkg.dsc
• line 54: TOOL_CHAIN_TAG        = GCC5

Then I tried to run 'build' but I occured errors below:

`uild.py...
: error 7000: Failed to execute command
make tbuild [/home/uefibc/src/edk2/Build/MdeModule/DEBUG_GCC5/IA32/MdePkg/Library/BaseLib/BaseLib]

build.py...
: error F002: Failed to build module
/home/uefibc/src/edk2/MdePkg/Library/BaseLib/BaseLib.inf [IA32, GCC5, DEBUG]
`

Any ideas? Thanks.

Hi,

please use the latest version of nasm. 2.14 is too old.

I ran into the same problem, in my case I upgraded ubuntu to version 22, so the nasm package was newer, and it fixed the problem.

try to checkout to older stable branch of EDK2 like edk2-stable202005

also checkout my project, that tries to make sense of edk's build system.
