Cannot apply patches

[buddyman1]

Hey I am on Ubuntu, after the qemu repo had been cloned I moved the patch into the qemu folder and then ran "git apply qemu7.0.0.patch"

I got the error "warning: unable to rmdir 'roms/edk2': Directory not empty" I ran the cmd again and got the errors:

Any help will be appreciated.

The qemu7.0.0.patch can only be used on qemu version 7.0.0, check the branch tag please.

[buddyman1]

Hey, so I downloaded qemu 7.0.0, I used: git clone https://gitlab.com/qemu-project/qemu/ -b v7.0.0 --depth 1 --recursive Also do i need to have qemu already installed?

[buddyman1]

I am new to this, so if you could explain what i need to do that will be great.

Thanks

You needn't install qemu, you can do follows:

# If you did this , skip
git clone https://gitlab.com/qemu-project/qemu/ -b v7.0.0 --depth 1 --recursive 
cd qemu

#Check if is in qemu folder
pwd
#!!!!Must be current QEMU folder
rm -rf ./*
#Recovery QEMU sources
git checkout .
#Apply patch again

If you see warning: unable to rmdir 'roms/edk2': Directory not empty only at first, it is success.please don't apply again, or you will get errors.
