I've asked Ian for help but he's not responded for whatever reason and I would like to solve the issue up front. Is anyone familiar enough with autoconf and has the free time to hold my hand through the process. I haven't got the patience to learn autoconf myself (fundamentally because I think its a heap of crap, waaaay too complicated to be worth the effort) but I would like to have the rest of the VM compiled with -fomit-frame-pointer, essentially for plugin performance, so I don't want to take the easy route and simply omit -fomit-frame-pointer throguhout, and I don't want to spend the time e.g. porting the Newspeak make framework, which would be a good thing in the long run.<br> <br> TIA<br> Eliot<br> </blockquote> <br> <br></div></div> Ian is on vacation.</blockquote><div><br></div><div>That explains it.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"><br> <br> Easiest might be to add -fno-omit-frame-pointer when your file is compiled, this should cancel a previous -fomit-frame-pointer.</blockquote><div><br></div><div>Right.</div></div></blockquote><div><br></div><div>Actually, no. -fno-omit-frame-pointer seems to *force* a frame pointer even on platforms that by default have none ... or is that what you need?</div><div><br></div><blockquote type="cite"><div class="gmail_quote"><div> My problem, however, is how to get autoconf to generate a specific compile rule for one file.
