wic missing squashfs

I keep getting this error:

| ERROR: A native program mksquashfs required to build the image was not 
found (see details above).

|

| Please make sure wic-tools have squashfs-tools-native in its DEPENDS, 
build it with 'bitbake wic-tools' and try again.

|


I have tried adding squashfs-tools-native to WKS_FILE_DEPENDS, but I get 
the same error.  any thoughts?

Hello.

Try using IMAGER_INSTALL:wic += "squashfs-tools"

Hello. 

Try using IMAGER_INSTALL:wic += "squashfs-tools" 


I have recently run into this (and did this in my layer)

IMO the wic imager should pre-install packages for everything file-systems 
it supports / usable in .wks files. I was going to submit a patch along 
these lines so that I could get rid of this directive in my downstream 
layer. Should I? This would improve usability / user-experience if you ask 
me. 

Thanks
Cedric

Hmm... I tend to disagree. Installing these tools takes time and
increases the attack surface of the build itself. By that we basically
penalize all users just because it makes things a bit easier for some.

Hmm... I tend to disagree. Installing these tools takes time and 
increases the attack surface of the build itself. By that we basically 
penalize all users just because it makes things a bit easier for some. 


attack surface? isn't the sbuild environment of the imager ephemeral?
moreover, users are encouraged to build within a (kas-)container, this adds 
another line of defense

as for build-times, we can quantify but I believe it is negligible.
little gains but increased pains (for some at least)?  

I believe we are reaching out to developers with varying levels of 
knowledge and that's ok because some just want to focus on their 
application development duties and do not care about the platform-level 
stuff, yet they have to use the platform tools (bitbake / isar) to get 
their job done. From that perspective, I would vote for lowering the 
barrier of entry
 
of course one approach could be to add some pre-processing task where we 
parse the wks file upfront to check file-systems that were selected 
(possibly with some shortcuts to avoid re-implementing a full wks parser in 
isar/meta/imagetypes*) but that sounds like adding unnecessary complexity.

anyhow, that's my view of the matter.

Yes, my concern is probably more of a theoretical nature. More packages
always increases the risk, but here it probably can be neglected.

If we can come up with a not too long list of packages that are
convenient for imaging, this trade off also might be fine.

Agree.

If the cost of including the packages is high, we likely need this. If
not, it is just over engineering.

Dude, **over engineering**... seriously?

Making your {customers, comrades, girlfriend} happy in letting them
live a smooth life without begging for your support can be considered
"over engineering" or a form of?

Think about it, all the time you need. Twice before answering, seriously.

I would recommend aligning with OE/yocto here, and it appears to me like
they demand quite a few tools by default:
