Cygwin but not really question

Cygwin but not really question

[Vince Rice]

This is a "do I even need to go further" question, but since it's related to a Cygwin source file but not on Cygwin, I thought I'd ask here rather than the main list (which doesn't deal with non-Cygwin questions), on the off chance someone might have pity on me and answer, all the while avoiding the hippos.

I'm a longtime cygwin user, and recently switched to a Mac (still using Cygwin in the Win/VM; does that count?). I would like use the conv.c program (u2d/d2u/etc.) on the OS X side. So, I dl'd the cygutils source, untarred it on the OS X side, and did a configure and make. The 'make' vomited all over the place (first four errors src/conv/conv.c:74: error: syntax error before ‘optCon’, replacing the 74 with 74-77).

I'm not much of a C programmer, but I tried to look around and see if I saw anything obvious, i.e. line endings, etc., but I didn't see anything. I looked on the line in question (static void usage(pOptContext optCon...), but there's nothing obviously wrong syntactically there. I went back and looked at the config.log, and saw that although getopt.h is present, popt.h isn't. But, it was just a configure test, so I guessed that should be OK, although, given the error above, maybe not.

I have XCode installed, so I have gcc (4.0.1) and all of the other unix-y tools.

So, before I spend any more time on this, is there a reason this WON'T install? I.e., does it depend on anything in the cygwin DLL or anything else that doesn't exist in a normal Unix-y environment? If so, then I'll give up and go find other tools to do the same thing (I just really like having everything in one program).

If not, I'll try to read up enough to see if I can figure out what's going on.

Thanks, and loose the hippos!

To extend the OS X's base Unix environment to be more Linux-like -- or 
Cygwin-like, if you prefer -- install Fink: http://fink.sf.net/  This is 
an APT-based packaging project which pulls in a lot of stuff that you 
find Linux and Cygwin, which was left out of OS X.  There is a dos2unix 
package:

	http://pdb.finkproject.org/pdb/package.php/dos2unix

So, after Fink is installed and configured for the first time, you just 
say "fink install dos2unix", and there you are.  You can use Bash 
aliases to get 'd2u' and 'u2d' if you don't want to retrain your 
fingers.  I find 'dos2unix' and 'unix2dos' a little more common.

Some people prefer MacPorts (http://www.macports.org/) which does much 
the same thing.  I happen to have started with Fink and have been happy 
with it, so haven't bothered to even try MacPorts.

And, in case it isn't obvious, this stretches the "vaguely Cygwin
related" to an atom thick thread.

This really is the kind of thing best discussed in a Mac OS/X forum not
a Cygwin forum.

While the configury checks for popt, some of the applications in
cygutils *require* popt. I should probably change the configury to fail
when it isn't found.

Note that the dos2unix package from fink, as recommended by cgf, is not
the same program as the one in cygutils. But that's okay; it's a very
simply task and any package you download will work fine, provided you
get it to compile.

For that matter, some other package might actually suit your needs
*better* -- because the cygutils tools do /not/ handle converting
to/from *MAC* line-endings.
