I've been having the same problem.  Here is what I know.<br>in the file <a href="http://config.in" target="_blank">.config</a> in /buildroot, there is a variable: <br>BR2_PACKAGE_LINUX_KCONFIG that is not set.  I have no idea what to set it to.  
<br><br>I posted the question which got me this answer:<br>grep -r BR2_PACKAGE_LINUX_KCONFIG target<br><br>should give you some clues in which <a href="http://config.in/" target="_blank">Config.in</a> it is defined.<br><br>
the result of that is this:<br>[ filtered for .svn exclusion and other devices ]<br><br>target/linux/Makefile.in:ifneq ($(strip $(subst ",,$(BR2_PACKAGE_LINUX_KCONFIG))),)<br>target/linux/Makefile.in:LINUX26_KCONFIG=$(strip $(subst ",,$(BR2_PACKAGE_LINUX_KCONFIG)))

<br><br>so maybe something like "/target/device/Arm/linux2.6.integrator926.config"<br><br><div class="gmail_quote">On Dec 15, 2007 10:41 AM, Lan Ngoc <
