Re: Cross-compiling hosted on Linux
Erm, no. Go to pipmak.sourceforge.net to see what the program I had in mind is. It's supported on Mac OS X, Linux, and Winblows, so what I was trying to to was use it's Xcode project file (or whatever it's called) to compile it on Linux for Mac OS X. I don't need to do this anyway, because it turns out that I can get it precompiled WITH the libraries, from the project site. So, never mind.

Re: Cross-compiling hosted on Linux
hmmm, however the requirements are: "Please note that in order to install and run MacPorts on Mac OS X, your system must have installations of the following components: 1. Apple's Xcode 3.0 Developer Tools for the Leopard platform or 2.4.1 for Tiger, found at the Apple Developer Connection site or on your Mac OS X installation CDs/DVD. [plus some others]" So as the OP was hoping to avoid Xcode, we are back to square 1.

Re: Cross-compiling hosted on Linux
The short of it is it is possible to cross-compile on linux using gcc, though it depends on whether or not the gcc on your Linux is compiled to permit cross-compiling. The long of it is I don't know anything about MacOSX's development environment, nor about how well gcc is integrated into it. And I don't know if MacOSX is one of the supported targets in gcc, though I suspect it is. The non-X Window System environment I am passingly familiar with - Win32 - requires its own libraries and headers, and I use the version known as MinGW instead of Cygwin; I assume there is something comparable for MacOSX? Eg, libraries for the various Macintosh operating system environments, Cocoa, etc? I do know gcc includes Objective C - *.m files - but I have never used gcc's Objective C myself, and would not know about its support for MacOSX. Likewise I don't know if Apple has made available a MacOSX cross-compiling development environment for Linux.
