Re: [OE-core] Creating a machine specific recipe for config file
Package management overhead seems like a small-ish price for being able to manage/coordinate custom configs with real depends. Did I mention I like 2) better?

Actually, that's not bad either. As long as the magic is documented, that sounds pretty good too.

What was your idea here - to replace the MACHINE-specific config for these packages - or to augment it with an optional mega-config package? The reason to get away from MACHINE-specific config changes to the regular package is from a re-use standpoint. If BSP_A and BSP_B both need different configurations of the FOO recipe, the right way today is for two machine specific versions of the FOO recipe/package to be generated. foo-ver-rel.BSP_A.rpm foo-ver-rel.BSP_B.rpm This eliminates a lot of potential re-use, and if it's a large package could add a lot of unnecessary space (and build time) to the system. Instead what we want is: foo-ver-rel.armv7.rpm foo-conf-ver-rel.armv7.rpm foo-conf-ver-rel.BSP_A.rpm foo-conf-ver-rel.BSP_B.rpm So the package management system will select the best package to meet the requirement automatically. You get to re-use the one foo package on all compatible system. And then you can choose from a default (not-configured), or a BSP configuration. Much quicker to package, install and takes (potentially) less space. (On a trivial hello-world example, it'll actually take more space, but get outside the trivial and it will be helpful.) I think it would help to provide a bit of background/motivation regarding what exactly we're trying to accomplish with this. That would help me form an opinion on 1 vs 2 anyway. So when talking with Saul I suggested that we do either #1 or #2.. and the base recipe (not configure) had a require or recommend of the configure file. The more I think about this, the more I think multiple small configuration files/packages makes sense.. due to various system configuration possibilities -- but using appropriate RPROVIDES we shouldn't prevent the system from allowing a single monolitic configuration for a BSP. --Mark -- ___ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.openembedded.org/mailman/listinfo/openembedded-core
