I'm not aware of any tool in gentoo right now that x-compiles and then makes the flash image. Mostly we all merge into an alt ${ROOT} and then go run genext2fs/mksqushfs/mkfs.jffs2 or whatever suits your needs for the type of flashable image you are creating. The gnap project does do building, merging and dumps out a flashable image when it's all done. But afaik gnap is mostly targeted at native compiles vs x-compiles. The qmerge util from portage-utils is an ipkg/apt* work alike. > So what's the approach for embedded > gentoo? Provide the tools & development environment for users and let them figure out what's best for the device they own. -- Ned Ludd Gentoo Linux -- gentoo-embedded@gentoo.org mailing list
