Dear all,
Would you please show me how I can build the final Astrobox SD image (like those from https://www.astroprint.com/downloads) from source code (https://github.com/AstroPrint/AstroBox)? I’d like to try this by myself rather than only get the image from the download page. Thank you a lot.
Compiling images from source is HIGHLY NOT RECOMMENDED and a major pain in the ass. 
The likelihood that something will go wrong is very high.
With that said, only @daniel could give you a definite answer on the exact process 
May I ask: why do you want to do this anyway? Are you trying to get it working on custom hardware?
@dilanka：
Thank you for your quick response for such a nightmare:-)
Actually I am expecting to do some debug or learning on Astrbox + Raspberry.
Till now I’ve built a Astrobox by myself, and also read some source code of https://github.com/AstroPrint/AstroBox. And I am trying to change the source code, such as .js and .py files. But don’t know how to check the effect.
So if there are some guide on the exact build/release process from source code to image, it would be a benefit for me.
I have been looking into this as well, hoping to get it working on a BBP fastbot board.
@dilanka,
Seems that Daniel is absent right now:-) And would you please help me on such below small question?
In the source code, there are many .js files, such as AstroBox\src\astroprint\static\js\app\views\control.js, but in the final image on Raspberry board, there is no such file.
And I know actually it is combined into the app.js in image with many other .js files.
So my question is how I can verify my own changes in control.js in source code? I mean how can I get such changes into the final images.
Thank you a lot.
Other than known customizations – I have done zero exploring of the Astrobox source code, nor do I have any interest in doing so anytime soon 
You are on your own on this one my friend 
– if you do discover a solution, feel free to post it here though!
@dilanka
Ok, I will be on my own way, and keep trying.
@daniel,
Any suggestion for us? Thank you a lot.
We haven’t yet focused on making the source easy to build as-is (something we need to do but haven’t had time).
Try editing or creating application.cfg file in the same directory as your config.yaml. The contents of that file should be:
ASSETS_DEBUG = True
ASSETS_AUTO_BUILD = True@Daniel,
Thanks. But I don’t quietly understand some part of your reply. Sorry for I am totally newbie here. Actually I have two questions here.
The 1st one is the source build step. I know this could not be easy. So let’s ignore this one now. Maybe someday you could give us more about this:-)
The 2nd one could possibly be easier. Let me explain more. As seen in the source code, we have these two folders, And in both, there is a gen\ folder with empty file there.
src\astroprint\static\css\gen
src\astroprint\static\js\gen
When we come to the Raspberry board, there are also two relevant folders, and I found many .js files in source code are combined/merged into fewer ones in image.
/AstroBox/src/astroprint/static/js/gen
/AstroBox/src/astroprint/static/css/gen
So my question is how these happens, and how I can merge/combine my change in source code level into the final image?
Thank you very much in advance.
@Daniel,
I can hack the final .js(eg, /AstroBox/src/astroprint/static/js/gen/app.js) in image directly to verify some change, but actually it is almost unreadable.
And I know this is absolutely NOT the normal way for development.
So could you pls help me on this newbie problem? How to combine/merge those changes of readable .js files in source code into the final unreadable .js in the final image? Any build script/tool to do such thing?
If you change the application.cfg file that I mentioned before, the software will use the individual .js files instead of the generated and combined .js one.
Do you mean the following steps?
-
Change the /etc/astrobox/application.cfg in image into
ASSETS_DEBUG = True
ASSETS_AUTO_BUILD = True -
For /AstroBox/src/astroprint/static/js/ and /AstroBox/src/astroprint/static/css/ folders in image, directly use the corresponding source code folders to replace them.
-
reboot my raspberry board
No, you need to clone the AstroBox repo on your raspberry pi first.
After you’ve cloned the system, you should stop the current one with:
sudo service astrobox stop
and start the new one using the repo you cloned. From the astrobox cloned directory:
python ./run --config /etc/astrobox/config.yaml
OK, let me try. Thank you a lot, and I will come back with the result soon:-)
@Daniel,
I tried your steps, but I failed with below errors, and seems fail to start the astrobox service. Any suggestion for me to move on?

@Daniel,
The above error of “OSError: [Errno 2] No such file or directory” is due to sass missing.
After I apt-get install ruby and apt-get install ruby-sass, the astrobox service can be started, and I can access the Astrobox’s web page from browser. Thank you a lot.
And I will continue to change those source code files, eg, .js files to see the result.
@Daniel,
Thank you a lot. Finally I can change the source code on raspberry board directly now.
On the other hand of our discussion, could you please show us how to generate the combined/compressed .js files and the .css files just like those in the downloaded image? I mean /AstroBox/src/astroprint/static/js/gen and /AstroBox/src/astroprint/static/css/gen.
We’re not planning on releasing our packaging tools at the moment but you don’t really need them to develop on the astrobox.
Please do create a pull request is what you’re doing should be consider part of the official release.
Ok, got it. Thank you again on the way.

Hey there, I followed all the steps mentioned above but still I am unable to run Astrobox from the source code. I am getting the following errors:

Help me figure this out, I have even installed sass and ruby as @dingcatdang mentioned still no luck.
