I'm having an issue with BusyBox v1.21 and piping. It seems as though piping is causing busybox to restart/crash.

This is for an arm platform cross compiled using gcc v3.4.1.  I don't know if it happens on i386, since I haven't built for that arch, just arm.  My .config is attached.  </blockquote> FYI, I recompiled with "CONFIG_TR=y" in my .config and the pipe is working now.   find . -name *.c -exec grep -Hi "CONFIG_TR" {} \; doesn't result in anything, so I'm not sure where the dependency is, if there even is one. - Coleman <blockquote cite="mid46144786.4080306@comcast.net" type="cite"> <blockquote cite="mid200704042011.01576.vapier@gentoo.org" type="cite"> <pre wrap=""><hr size="4" width="90%"> _______________________________________________ busybox mailing list <a class="moz-txt-link-abbreviated" href="mailto:busybox@busybox.net">busybox@busybox.net</a> <a class="moz-txt-link-freetext" href="http://busybox.net/cgi-bin/mailman/listinfo/busybox">http://busybox.net/cgi-bin/mailman/listinfo/busybox</a></pre> </blockquote> <pre wrap=""> <hr size="4" width="90%"> _______________________________________________ busybox mailing list <a class="moz-txt-link-abbreviated" href="mailto:busybox@busybox.net">busybox@busybox.net</a> <a class="moz-txt-link-freetext" href="http://busybox.net/cgi-bin/mailman/listinfo/busybox">http://busybox.net/cgi-bin/mailman/listinfo/busybox</a></pre> </blockquote> </body> </html>
