gcc cross compiling

gcc cross compiling

[rudy_b]

Hi, 
I would really appreciate some help.
I have a VERY simple C++ program, it is probably not even more than 30 lines
of code, and all it is doing it is mostly dealing with File IO's. I will be
honest, and the only library that I included is something called
boost::filesystem, but I did search and found out that the "boost" library
should run on all platforms. Granted that if this is true, is there a simple
way for me to cross platforms.
As I said, I don't have anything fancy, it is just simple c++ code, with
opening files, and reading files, and maybe renaming some files, and that is
about it. It is a command line C++ code, and doesn't involve any fancy
GUI's.
I developed this C++ code on a linux machine, with the following version
info:
Linux 2.6.18-164.el5 x86_64
And, I have access to most of gcc versions (4.3.5, 4.4.0, 4.5.1, 4.5.2,
4.6.0)

And, all I want to do is to bring this code over to my classic Mac:
Mac OS leopard 10.6

I tried to read more about this, and I came across the following link:
http://www.sandroid.org/imcross/

This looks very complicated, and just to do that it will take me days, to
get it going, and plus I would need a huge storage place on my disk to
install all these packages.

I am really hoping there should be a way to bring my simple code over from
Linux to Mac, without going through all these massive steps listed above. 

my c++ code, has only one function() and then the main().
My guess would be that there should be way simpler method of doing this,
since my  code is fairly simple.

I really appreciate some help.

thanks, 
RB

Just install a compiler on your Mac, then compile the code on the Mac.

No need for Boost for simple programs since you probably have what you need.

For what its worth, I took a quick look at boost yesterday. I found
four problems with their threading and synchronization code in about
15 minutes. I don't believe Boost gets the same scrutiny from the same
caliber of folks that other projects, such as OpenSSL GDB, and GCC do.

Xcode. Its a free download at http://developer.apple.com/xcode/ (and
might already be installed). Best of luck with Xcode 4.x.

Looks like a lot of work to me. Stick with Xcode and a Terminal.

After installing Xcode (for the development files and libararies), you
can work from a Terminal.

Ditch Boost.
