Subject: Verify --with-linux source directory exists
X-Git-Tag: debian/0.7.9-2~135^2
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=251677e98fd41170a885095626a9247d609661b0;p=mirror_spl-debian.git

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.

Closes #162
