So you have to configure each package for each target manually, which leads the whole point of autoconf ad absurdum ;-o > But most embedded projects haven't that much number of "large tools" - > mainly because the space is limited. I'm probably not quite representative, but I'm using crosscompile techniques also for building to the same arch - mainly for QM reasons. > pkg-config generated (and generates? - I didn't check recently) > references to libraries including the full absolute path (which is the > one at build time.

So you simply build your .pc files as usual (w/o sysroot prefix) and set the sysroot prefix via env on the pkg-config call. > > Can you please explain ?

It does not install anything. Probably you're looking for sysroot ? cu -- --------------------------------------------------------------------- Enrico Weigelt == metux IT service - http://www.metux.de/ --------------------------------------------------------------------- Please visit the OpenSource QM Taskforce: http://wiki.metux.de/public/OpenSource_QM_Taskforce Patches / Fixes for a lot dozens of packages in dozens of versions: http://patches.metux.de/ --------------------------------------------------------------------- -- To unsubscribe from this list: send the line "unsubscribe linux-embedded" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
