https://sourceforge.net/p/libjpeg/bugs/12/Recent changes to 12: x86_64 CPU is not recognizedenTue, 15 Sep 2015 13:26:53 -0000https://sourceforge.net/p/libjpeg/bugs/12/?limit=25#9cee<div class="markdown_content"><p>This project is a dead project. Look at <a href="http://www.ijg.org/" rel="nofollow">http://www.ijg.org/</a> or <a href="http://www.libjpeg-turbo.org/" rel="nofollow">http://www.libjpeg-turbo.org/</a> for projects which are still alive. The former is the official IJG version and supports major new features (rarely used) and the latter is a performance refinement of the 6b version to be quite a lot faster. There is also the Mozilla JPEG project at <a href="https://github.com/mozilla/mozjpeg" rel="nofollow">https://github.com/mozilla/mozjpeg</a>, which focuses on producing smaller files.</p></div>Bob FriesenhahnTue, 15 Sep 2015 13:26:53 -0000https://sourceforge.net912f45f5d75b433a7182af6935ab13ddfc8c6c22https://sourceforge.net/p/libjpeg/bugs/12/<div class="markdown_content"><p>While compiling release 6b on a Linux box (RHEL4 in my case) I get the following error message:</p> <div class="codehilite"><pre><span class="nv">$ </span>./configure --enable-shared --enable-static ... checking <span class="k">for</span> ranlib... ranlib checking host system type...
