Some errors when build on ubuntu 20.04 (installed via virtualbox on windows)

[jundai20]

Tested on a brand new ubuntu 20.04 on Virutalbox, meet following issues:

./build --download-dependencies qemu-buildroot

1. Need to modify /etc/apt/sources.list to add back deb-src
   ==> uncomment deb-src

2. Need to manually install following packages
   builddeps:qemu : Depends: libgtk-3-dev but it is not going to be installed
   Depends: libvte-2.91-dev but it is not going to be installed
   Depends: libepoxy-dev but it is not going to be installed
   Depends: libgbm-dev but it is not going to be installed

3. The openssl git name has a typo. Instead of openssl, it should be openssl.git
   qemu/roms/edk2/.gitmodules ==> openssl-> openssl.git

4. It will kill ubuntu GUI mode, smash the host linux
   After ./build --arch aarch64 --download-dependencies qemu-buildroot, the ubuntu GUI is disspear. Still can login, but it is CLI mode.

5. Pending, DO not know what happened, give up here :)
   Later, the host out/buildroot/buid/default/host-uitl-linux-2.35.2 will fail, the error is,
   configure: error: C compiler cannot create executables

1 and 2: discussed at https://cirosantilli.com/linux-kernel-module-cheat/put-source-uris-in-sources and automated in Docker:

linux-kernel-module-cheat/build

Line 552 in 0acd34a

sources_txt = re.sub('^# deb-src ', 'deb-src ', sources_txt, flags=re.MULTILINE)

Not automated in other hosts because of fear of blowing up system :-)

3. I suspect that both openssl and openssl.git work since they are GitHub URLs and you can git clone either, and that instead it was a one off internet/github problem. I have also been able to checkout that version of QEMU just now.

4 and 5. Not sure about those. Is your simulated disk large enough?

Thanks for the information. Yes, I created a 42G VirtualBox fixed size vdi for this purpose.

BTW, follow the following link, I've brought back the GUI. There should be some gdm version confliction.

sudo apt purge gdm gdm3
sudo apt install gdm3 ubuntu-desktop
systemctl restart gdm
