From 7ea0060e3b5c0f4d261cf4291bcd160ec94164c2 Mon Sep 17 00:00:00 2001 From: graham.gower Date: Thu, 26 Nov 2009 23:09:44 -0500 Subject: Remove enum opkg_error. The return codes aren't particularly useful and trying to have a useful one for every error scenario would be like extending errno. Good error messages via opkg_message() are far more appropriate. git-svn-id: http://opkg.googlecode.com/svn/trunk@395 e8e0d7a0-c8d9-11dd-a880-a1081c7ac358 --- (limited to 'libopkg/opkg_install.c') diff --git a/libopkg/opkg_install.c b/libopkg/opkg_install.c index 819410f..303877e 100644 --- a/libopkg/opkg_install.c +++ b/libopkg/opkg_install.c @@ -70,7 +70,7 @@ satisfy_dependencies_for(opkg_conf_t *conf, pkg_t *pkg) "mentioned above do not yet exist (try 'opkg update').
