Change 19150 by [EMAIL PROTECTED] on 2003/04/05 21:10:00
Subject: LD_PRELOAD hack, still badly flawed / a solution
From: Enache Adrian <[EMAIL PROTECTED]>
Date: Thu, 3 Apr 2003 15:50:48 +0300
Message-ID: <[EMAIL PROTECTED]>
On linux, when building a shared library, generate
a small shell wrapper, "preload", that preloads libperl.so
only if it exists. Useful when the 'make' process stops
before the link phase.
