From 56a517ae3ab9b2d848a5e671d276396970ed4718 Mon Sep 17 00:00:00 2001 From: Brian Behlendorf Date: Thu, 29 Nov 2012 20:19:25 -0800 Subject: [PATCH] Verify --with-linux source directory exists Previously this check was only performed when ./configure was attempting to autodetect your kernel source directory. But we should also handle the case where --with-linux was provided and is obviously wrong. This way we catch the error before invoking make and compiling the source with an incorrect autoconf results.
