From: Paul Eggleton Date: Wed, 19 Jun 2013 16:53:06 +0000 (+0100) Subject: classes/buildhistory: fix error when no packages are installed X-Git-Tag: 2015-4~6116 X-Git-Url: https://code.ossystems.io/gitweb?a=commitdiff_plain;h=03d86123e9e804e62de38effd307f070d7863080;p=openembedded-core.git classes/buildhistory: fix error when no packages are installed "xargs -n1 basename" will execute basename even if there are no lines piped into it, causing a "basename: missing operand" error if no packages are installed, which will happen for the target portion of buildtools-tarball. (xargs' -r option could have been used here, but it is a GNU extension and I thought it best to avoid that for the sake of future interoperability).
