Hi All,<br> <br> I need to modify the autoconf scripts in the unix build to arrange to omit the -fomit-frame-pointer flag form on e of the files in Cog. 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> <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></div></blockquote><div><br></div><div>Right. Somewhere (and I haven't found out where) the autoconf configuration decides to apply -fomit-frame-pointer, which is fine as it generates faster code, etc. But I need (actually, want; I could work around, but shouldn't have to) a frame pointer for one file, and a subsequent -fno-omit-frame-pointer will override a preceeding -fomit-frame-pointer with the compilers I'm aware of.</div>

My problem, however, is how to get autoconf to generate a specific compile rule for one file. I can define the alternative COMPILEALT macro but I can't yet figure out how to spit out that rule for a specific source file withoput hacking it at the wrong place. But I'm getting closer :/</div>

So I think I have to duplicate the ${srcs} collection and processing in mkmf.</div>
