Support for Openwrt Imagebuilder and SDK #649

Open FreifunkUFO opened 8 years ago

FreifunkUFO commented 8 years ago

on openwrt special changes or more packages are usually done with Imagebuilder / SDK.

Gluon as an openwrt-project should provide Imagebuilder and SDK!

belzebub40k commented 8 years ago

Would be very handy to have the imagebuilder as we build images for 3 communities with the same codebase and the main differences in site.conf. Imagebuilder would save us a lot of time and would make sure that binaries for all communities are identical.

Did you already made some progress in adding imagebuilder to Gluon?

neocturne commented 8 years ago

We probably won't have a distinct image builder with Gluon in the near future. A Gluon build will take just a few minutes - about the time the OpenWrt image builder would take - if a fully built Gluon tree is re-built without cleaning it inbetween.

To build multiple sites, just set GLUON_SITEDIR and GLUON_OUTPUTDIR to three different directories and re-run make for the desired targets.

As a general rule: when doing changes to site.conf or site.mk, a make clean is never necessary; this is also true for changing the GLUON_SITEDIR (unless the sites have different modules files). You only need to clean after a git pull/make update.

Thanks for the hint. Wasn't aware of that but sounds reasonable.

FreifunkUFO commented 8 years ago

the compiling time is NOT important. imagebuilder is for using openwrt in a normal "openwrt" way.

the SDK is even more important! its needed by almost everyone who wants to build own packages, other normal ("gluon-out-of-scope") openwrt packages and for rebuilding (updated) openwrt packages in the future!

p.s. did you read about that airos-virus? AirOS/UBNT didnt publish their SDK any more, so people are forced to use outdated firmware with that old SDK.

neocturne commented 8 years ago

I agree that the SDK would be nice (although I've never used the OpenWrt SDK, but always use a normal OpenWrt tree for package builds). Can the SDK build kernel modules?

For userspace packages, a "Gluon" SDK is not needed at all, you can just use an OpenWrt CC SDK.

FreifunkUFO commented 8 years ago

yes, SDK is for builing/compiling modules and packages. each gluon (f.i. download folder for a specific town) should contain IB+SDK! openwrt-cc-sdk cant be used, because gluon is mostly openwrt-cc-trunk or openwrt-bb
