--=-sA4HFO2L5L9Tiro52BTc Content-Type: text/plain Content-Transfer-Encoding: 7bit Hmmm, I guess I just assumed that since ldconfig had cached the absolute path to the library, ld would not need to know the library path as well, but for some reason it did. What ultimately fixed the problem was hardcoding the -L /usr/local/lib in the configure script, since it refused to pick up that directory any other way. Thanks for your help. As a point of curiosity, I'd still like to know why ld would still need the -L /usr/local/lib if the full path to the library is already in the cache? -- Justin Hopper jhopper@spry.com UNIX Systems Engineer http://www.spry.com --=-sA4HFO2L5L9Tiro52BTc Content-Disposition: inline Content-Description: Forwarded message - Re: Mysterious problem with ldconfig and ld Content-Type: message/rfc822 Return-Path: <matt@gsicomp.on.ca> Delivered-To: jhopper@spry.com Received: (qmail 13533 invoked from network); 4 Jan 2003 04:02:22 -0000 Received: from tomts21-srv.bellnexxia.net (209.226.175.183) by spry.com with SMTP; 4 Jan 2003 04:02:22 -0000 Received: from gabby.gsicomp.on.ca ([65.95.187.110]) by tomts21-srv.bellnexxia.net (InterMail vM.5.01.04.19 201-253-122-122-119-20020516) with ESMTP id <20030104040642.GXZT7873.tomts21-srv.bellnexxia.net@gabby.gsicomp.on.ca>; Fri, 3 Jan 2003 23:06:42 -0500 Received: from hermes (hermes.gsicomp.on.ca [192.168.0.18]) by gabby.gsicomp.on.ca (8.12.6/8.12.6) with SMTP id h0444wk5056314; Fri, 3 Jan 2003 23:04:58 -0500 (EST) (envelope-from matt@gsicomp.on.ca) Message-ID: <004001c2b3a6$b3c4fe10$1200a8c0@gsicomp.on.ca> From: "Matthew Emmerton" <matt@gsicomp.on.ca> To: "Justin Hopper" <jhopper@spry.com>, <freebsd-questions@FreeBSD.ORG> References: <1041652526.27245.29.camel@home.gusalmighty.com> Subject: Re: Mysterious problem with ldconfig and ld Date: Fri, 3 Jan 2003 23:06:47 -0500 MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 6.00.2800.1106 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Content-Transfer-Encoding: 7bit > This may be a very simple fix, but so far I've found no solution.
