Hi,

My build environment is:- rahulravi26@ubuntu2004-VirtualBox:~/qemu-buildroot/linux-kernel-module-cheat$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 20.04.2 LTS Release: 20.04 Codename: focal

I am trying to build using below command. ./build --arch aarch64 --download-dependencies qemu-buildroot

But getting the below error. ../../../../submodules/qemu/tests/fp/meson.build:27:0: ERROR: Include dir berkeley-softfloat-3/source/include does not exist.

A full log can be found at /home/rahulravi26/qemu-buildroot/linux-kernel-module-cheat/out/qemu/default/opt/meson-logs/meson-log.txt

Hmm, not too sure what is going on.

On my machine ./submodules/qemu/tests/fp/berkeley-softfloat-3/ exists, does it not exist for you?

That directory a submodule of QEMU as seen on .gitmodules:

[submodule "tests/fp/berkeley-testfloat-3"]
    path = tests/fp/berkeley-testfloat-3
    url = https://git.qemu.org/git/berkeley-testfloat-3.git

so I would try:

cd submodules/qemu
git submodule init --update

I'm going to try a Docker 20.04 build as well.

./submodules/qemu/tests/fp/berkeley-softfloat-3/ exits on my workspace too.

But inside that only .git file exits having content of gitdir: ../../../../../.git/modules/submodules/qemu/modules/tests/fp/berkeley-softfloat-3

OK. I did the Docker build right now https://github.com/cirosantilli/linux-kernel-module-cheat/tree/38eb67ad2ec46b58dbc701073ce0e980fad7788b#docker with --arch aarch64 on a fully clean repo and it just worked, so it isn't something I can reproduce, I can only give the unsatisfactory guess that the submodule update failed for a transient network reason.

Try to work around by using git submodule init --update manually inside submodules/qemu to ensure the submodule is update, and then try running again. Let me know if you find anything else.

Fresh clean build actually solve the issue. Thanks for your support.

Do you have any command to clean the complete repo, instead of making fresh build?

The build is under out/, so rm -rf out cleans it. But in your case it was a submodule issue, so not sure what's the cleanest approach, I think this works:

rm -rf submodules
git checkout -- submodules
