Trying to build Gem5 on ubuntu 22: native-elf-format: Permission denied or not found

I am trying Gem5 for the first time and I am using Learning_Gem5 as guide. I have a dual boot system (Windows 11 and Ubuntu 22.04.2) and I am doing this on Ubuntu.

When I reach this step

python3 `which scons` build/X86/gem5.opt -j9

I encounter an error which terminates the building.

scons: Building targets ...

scons: building terminated because of errors.

I searched and I found some stuff about making a link to a python directory and changing from CRLF and LF but I couldn't figure out what is going on and what should I do.

Any help is appreciated!

Update: Barmar's right. I used

dos2unix cpt_upgrader.py

and it was fixed. But I encountered another problem :(

It says that "native-elf-format.h" does not have execute permission. When I give the permission, it says:

Any ideas?

  • I found the solution! I used this link and ran dos2unix over all of the files in the repository.
