<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">Hi all,<br><br>I made the mistake of upgrading to OSX 10.5 (had to rebuild my entire system) and am trying to get ITK/VTK/FLTK/InsightApplications up and running again. ITK and VTK built flawlessly. FLTK gave me some headaches (error: libGL.dylib related; solution:<a href="http://developer.apple.com/qa/qa2007/qa1567.html)">http://developer.apple.com/qa/qa2007/qa1567.html)</a>, but I finally got it to built.<br><br>InsightApplications (CVS) is a no go. At 30% (DicomImageViewer) I get the following error:<br>ld: library not found for -lpng<br>collect2: ld returned 1 exit status<br>make[2]: *** [DicomImageViewer/DicomImageViewer] Error 1<br>make[1]: *** [DicomImageViewer/CMakeFiles/DicomImageViewer.dir/all] Error 2<br>make: *** [all] Error 2<br><br>I have FLTK and VTK enabled. I don't see any CMake options for PNG libraries. I had the USE_SYSTEM_PNG options turned OFF when building FLTK and ITK. (CMakeCache.txt file makes email too big)<br><br>Any insight is greatly appreciated.<br><br>Regards,<br>Robert<br><br></body></html>
