Re: Front end development question

[Josh Reese <jreeseue at gmail dot com>]

Ah perfect. It turns out there was a typo in my Make-lang.in so oasspec.c wasn't getting recompiled. 
If I can trouble you with a couple more questions. The first is simple:  for what architecture was gcalc 
developed? I am not able to compile some of it natively on OS X. Second, I am wondering at what point
gcc calls lang_parse_file()? My goal for this front end is to parse a language I wrote into C and then have 
gcc take over from there. So, if there is anything in there that you might have some advice about I would be
most appreciative.

As always thank you for your time,
Josh

So, after looking much through gcalc I realized my error and was able to get everything running for the most part. However, once everything was installed and I run my driver:

I've created basically a skeleton version of gcalc but am not sure what is preventing gcc from calling my driver. I haven't seen anything in the language configuration files or anything that seems to have any relevance to this. I'm wondering if you guys have any ideas on this one. Thanks again for the help, I do sincerely appreciate it.
