Koen just noticed that his eglibc was missing accept4(), due old kernel headers and likely something missing in eglibc's itself. That was not visible as a compile-time error, but was causing issues. I'd check if uclibc implements that as well. -- Gustavo Sverzut Barbieri http://profusion.mobi embedded systems -------------------------------------- MSN: barbi...@gmail.com Skype: gsbarbieri Mobile: +55 (19) 9225-2202 _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
