[Buildroot] How does an offline build work?

[Buildroot] How does an offline build work?

[Arun Reddy]

I was curious as to how an offline build works.

When I first starting using Buildroot, I downloaded a snapshot for that day.
As I used that same snapshot for about a month, I would run into different
Buildroot issues, which came up whenever new changes were implemented. I
assumed that whenever I typed "make" Buildroot is automatically being
updated with those changes which could be affecting certain things.

I am now using Subversion access so I can update the source tree whenever I
want, but if I were to go back to using the Buildroot snapshot image, will
doing an offline build "make source" allow me to do a build without
Buildroot being updated? Or is it just a way for all the files, packages,
etc, to be downloaded first so that I can continue the build in a place
where I do not have network access?

Could someone clarify this? The Buildroot documentation doesn't have a
detailed explanation on how the offline build is supposed to work. Thank
you!

Buildroot itself never gets updated by running make.

make source downloads the tarballs (E.G. source code) of all the
enabled packages into the download directory (dl by default). It is
indeed meant for offline use, E.G. you connect to the internet and run
make source, and once it is completed you will have all the needed
tarballs in your download directory and you can do the build without
network access.

offline has nothing to do with this.

It may not be detailed but answers all you asked above.
$ make help

and read everything (at least below "Miscellaneous:"). Twice. :)
And then, right in the mentioned README the above is documentend
extensively.

HTH,

Thank you for the explanations. Looks like a snapshot will remain as it is
which is good news.
