openssh-dev package and populate_sdk conflicts

openssh-dev package and populate_sdk conflicts

[Matt Johnston]

Hi OE list,

Recently OpenBMC merged a change to install openssh-sftp-server package
alongside dropbear sshd [1]. That caused a conflict in "populate_sdk" which
installs all available -dev packages [2]. 'openssh-dev' pulls in an
'openssh' -> 'openssh-sshd' dependency which conflicts with 'dropbear' [3].

What would be the recommended way to handle that situation? For now OpenBMC
has merged a change to disable building openssh-dev (it's empty since
openssh doesn't have libraries) [4].

Should non-library packages handle -dev packages differently? The default 
-dev package comes from bitbake.conf .

Cheers,
Matt

perhaps set

RDEPENDS:${PN}-dev = ""

in openssh

I had a similar problem. It set the following in my rootfs image recipe:

# SDK: openssh-dev cannot be installed because dropbear is already installed.
PACKAGE_EXCLUDE_COMPLEMENTARY += "openssh"
