There's a fair chance that a host with a sufficiently old tar also needs other updates, and that's when buildtools is used (which includes tar).

The hosts we talk about (Debian 7, CentOS 6) work fine for normal usage without having to install buildtools. Really? You must have added *something* on top of CentOS 6 because last I checked its git, tar and python versions supplied out of the box were way too old to even get the build to start.

The hosts we talk about (Debian 7, CentOS 6) work fine for normal usage without having to install buildtools. Having to install them for a situation that could also be dealt with by bitbake automatically seems not very user friendly. On IRC, Ross suggested that I should rewrite the regular tar recipe such that it installs tar as opt-in binary and remove the (mostly obsolete) tar-replacement-native). I'll send updated patches based on that. -- Best Regards, Patrick Ohly The content of this message is my personal opinion only and although I am an employee of Intel, the statements I make here in no way represent Intel's position on the issue, nor am I authorized to speak on behalf of Intel on this matter. -- ___ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.openembedded.org/mailman/listinfo/openembedded-core
