I clean up my patch <a href="https://www.jfrog.org/svn-jfrog/openjdk/patch/SplashScreen_libpng12.patch">here</a>, and tested before/after on my <a href="http://www.jfrog.org/wiki/index.php/Fred:OpenJDK_Page">config</a> only.

Sorry, I missed the part where you stated the name of the macro ;-) I used ALT_EXT_LIB_PNG. By the way, I have a feeling that a movement to use more and more library from the host OS (especially on Linux) is going on. Am I wrong?

<br>Because, with this macro set the j2se image will not run on a system with no libpng12. That sounds a little strange to me.<br><br>Anyway, hope it helps.<br><br><div><span class="gmail_quote">On 10/12/07, <b class="gmail_sendername">

This is a known issue. Anyway, thanks for reporting it! Please refer to<br>the following bug to track the status of the problem:<br><br><a href="http://bugs.sun.com/view_bug.do?bug_id=6613927">http://bugs.sun.com/view_bug.do?bug_id=6613927

</a><br><br>Currently the bug is being fixed.<br><br>Concerning the possibility of using an external libpng library, we've<br>got the following bug report:<br><br><a href="http://bugs.sun.com/view_bug.do?bug_id=6565114">

http://bugs.sun.com/view_bug.do?bug_id=6565114</a><br><br>However, we're postponing the fix because the submitter of the patch<br>haven't prepared a clean patch yet. The main reason to use a slightly<br>more comprehensive patch is to be able to use both the internal version

<br>of the library and the external one (if the developer defines the<br>EXTERNAL_LIBPNG macro when building OpenJDK). It would be very helpful<br>if someone could provide a clean patch for the latter bug.<br><br>--<br>best regards,
