Hi Vaclav,
<div class=""><br class="">
</div>
<div class="">Thanks for the input. I've been out of town and have not been able to look into this until today. </div>
<div class=""><br class="">
</div>
<div class="">As far as I can tell, I do not have cpp anywhere in any of the Mac binaries I've done, although I do have a C++ compiler installed. All previous versions compiled and built without this error, and they run fine. So what was changed between 8 October
and the release of 7.4.2 that makes configure fail if cpp is not found? Where should I look?</div>
