Hello everyone,

I plan to port my xcode app to windows, and googling showed that cocotron
is the right solution.
My xcode is 4.3.1 and Mac OS X 10.7.4.

I follow tutorial from this
link http://lacquer.fi/pauli/blog/2012/02/win-win-with-cocotron-part-1/,
everything looks fine, until I ran this command,
 $sudo ./install.sh

where I got below errors,

Could someone please tell me what's wrong? What's the right steps to
install CDT?

Thanks you advanced.

You appear to have a gcc installed somewhere that is not configured to
support objective-C. Make sure to remove it from PATH so that the system
gcc supplied by Apple is found instead, which has objc support compiled in.
The output produced by gcc -v should then have
"--enable-languages=c,objc,c++,obj-c++" somewhere in it. Then start a new
install.

That should not be the problem, as Joyce is trying to build the Cocotron
cross-compiler gcc, which doesn't require Objective-C. There is a
long-standing problem with compiling gcc using Apple's standard llvm
compiler, hence my tutorial's instructions to use another compiler instead
to build gcc for Cocotron. Joyce appears to be using the "HPC"
(http://hpc.sourceforge.net/ ) gcc build, which has worked for me in the
past.

Joyce, are you on Mountain Lion? If so, that might be the issue: the HPC
GCC installer provided in my tutorial is perhaps not compatible with
Mountain Lion (10.8 was not out when I wrote the tutorial).

On the HPC GCC page, they appear to have a build specifically for Mountain
Lion:
http://hpc.sourceforge.net/

It's the download labelled "gcc-mlion.tar.gz (4.8)". You could install this
version of GCC and see if it works.
