[SailfishDevel] Compile without Scratchbox2 environment

Mon Jan 8 09:27:41 UTC 2018

Hi Yuvraaj,

I think you mistakenly consider "Sailfish OS Platform SDK" and Scratchbox2 for the same thing. Sailfish OS Platform SDK is a root filesystem image with Scratchbox2 and other tools preinstalled. In theory you could install sb2 directly on your workstation but the SDK exists for your convenience. chroot and bind mount is used to enter the SDK but sb2 itself is not a chroot nor bind mount based - sb2 runs with normal user privileges.

Normally you enter the SDK using the /mer-sdk-chroot script which basically does bind mount and chroot. I am quite sure it is possible to repackage the SDK as a Docker image without the need for superuser privileges. Look into mer-sdk-chroot to learn what is needed to enter the SDK.

You can read more about the various components of Sailfish OS SDK e.g. here https://sailfishos.org/wiki/Platform_SDK_Target_Installation#Platform_SDK_Targets_and_Toolings

BR,
Martin

The plan is to package up each Sailfish target into a Docker image to be used in a CI system.
For my purposes, Docker is a easy-to-use chroot that's also easy to share and deploy as compared to a virtual machine with a toolchain in sb2.

I do know that sb2 is more than just a chroot with bind mounts, but thats all I really need: a pre-populated chroot with bind mounts. Docker fits that bill quite nicely.

No, I don't want multiple targets in the same image.
No, I don't need the management of multiple build targets within the same Docker image.
I don't want any of the other sb2 features: I dont need Xephyr, I don't need to automagically run the compiled binary under qemu, etc.

Necessity is the mother of this re-invention.
Can you help?

Thanks,
-Yuvraaj

I think however what you are trying to do is a bit unusual, to say the least.
Intending to use (at least as I understood it) docker as a substitute for SB2 is "wrong" (if you pass me the word).
sb2 is more than "just" a virtualization layer bind-mounting directories. It manages build targets, for one, which docker does not know about,
and never will. Yes, of course you can have a single docker image for a single build target, with all the replica which comes with it;
or you can have one docker image with multiple toolchains / target envs; but then you have rolled your own sb2.

I cant but recall the words : those who do not understand Unix, are doomed to reinvent it, poorly.

Best,

I know it is possible to create a Docker image with sb2 in it; I've done that for other sb2 toolchains - Maemo and Harmattan.
However, those images can only run as privileged Docker containers because of sb2 bind mounts (I think).

I'd like to avoid being forced to run privileged Docker containers.
Also, running sb2 inside a Docker container seems like inception.

If it is possible to install the Sailfish toolchain without sb2, it should be possible to capture that into a non-privileged Docker image. (I hope)

The documentation for anything related to scratchbox is either hard to google or has broken links to maemo.org<redir.aspx?REF=8iQEVyQxyFm_eS2gZlNYK5u_P4QpHfErlhTQ47Fpe_jEBSHKclbVCAFodHRwOi8vbWFlbW8ub3Jn> or is just non-existant.

As to why Docker and not sb2: "Why not?" and "Better documentation"

Thanks,

Out of curiosity, what's blocking you from using scratchbox?

Any other ideas?

Hi all,

Is it possible to compile for sailfish without using scratchbox2?

Thanks,

Sure, just compile in the device itself... :)
