Description Paulo Neves 2022-08-08 13:39:20 UTC

The reference manual section for "required packages[1]" has more entries than the ones required. Specifically it includes entries like (iputils-ping, libegl1-mesa libsdl1.2-dev and  mesa-common-dev) which are likely related to running qemu, a process that is not required to build and use the Yocto project.

xterm is also not required for building anymore as well[2].

Finally python3-distutils should be added as per insane check[3].

Comment 1 Michael Opdenacker 2022-08-11 14:38:22 UTC

Will test which requirements are still necessary.
We are supposed to include packages that we need to run QEMU.
xterm is probably not necessary any more indeed.

Comment 2 Michael Opdenacker 2022-08-11 14:39:46 UTC

Note from Alex Belloni: we build libsdl:

#
# By default native qemu will build with a builtin VNC server where graphical output can be
# seen. The line below enables the SDL UI frontend too.
PACKAGECONFIG:append:pn-qemu-system-native = " sdl"
# By default libsdl2-native will be built, if you want to use your host's libSDL instead of 
# the minimal libsdl built by libsdl2-native then uncomment the ASSUME_PROVIDED line below.
#ASSUME_PROVIDED += "libsdl2-native"

Comment 3 Michael Opdenacker 2022-08-11 15:06:11 UTC

Would be useful to mention which packages are just needed for QEMU.

Comment 4 Michael Opdenacker 2022-11-03 15:15:01 UTC

A patch was sent by Jose Neves to remove xterm:

Comment 5 Michael Opdenacker 2023-05-03 08:50:02 UTC

Note that SDL host packages are no longer needed to run QEMU, even without the "nographic" option. This was tested on Ubuntu 22.04.

Comment 6 Michael Opdenacker 2023-05-03 09:03:00 UTC

Just sent a patch to remove no longer necessary host packages:

I had to install sdl2-image because of:

Bulk move of 5.1 M4 to 5.2 M2 as approved by AlexB.

Comment 9 Antonin Godard 2025-06-06 07:42:31 UTC

Bulk move of bugs I am assigned to from Milestone 5.2M4 to 5.3M1.
