Subject: [PATCH v2] configure.ac: option for user-defined-trusted-dirs
Date: Thu, 2 Jan 2020 15:25:10 -0800 [thread overview]
Message-ID: <1578007510-24831-1-git-send-email-justinpopo6@gmail.com> (raw)
From: Justin Chen <justinpopo6@gmail.com>
User-defined-trusted-dirs is a variable used for adding additional
default library search dirs for the dynamic loader. Add the ability
to allow users to set it from the configure script.

produce a lot of output, some of which may look like errors from 'make'
but aren't. Look for error messages from 'make' containing '***'.
