I'm trying to build the GCC Cross-Compiler, following the wiki. I got as far as
../binutils-2.23.2/configure --target=$TARGET --prefix=$PREFIX --disable-nls

Running this with Cygwin, it gave me this error:
/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld: cannot open output file confest.exe: Permission denied
*** The command 'gcc -o confest -g -O2 confest.c' failed.
*** You must set the environment variable CC to a working compiler.
rm: cannot remove 'conftest.exe': Permission Denied
rm: cannot remove 'a.exe': Permission Denied

I did some research and learned that it has to do something with Win7's file sharing, but I still failed to find a solution. Do not suggest Ubuntu, I don't have an available machine to install it right now.

Run it as administrator.

I did and it gave me:
checking whether the C compiler works... configure: error in '/usr/src/build-binutils':
configure: error: cannot run C compiled programs.
If you ment to cross compile, use '--host'

For some reason it now gives me the error regardless of whether I'm running it as Admin or not.

What does the config.log file have to say about the failure? It sounds like your PATH isn't correctly set or your C compiler isn't properly installed.

I tried it on a different computer and it gave me this error.

Try disabling any anti-virus programs. And try Googling the error message.

With the antivirus disabled on WinXP it builds beautifully.

Following the Bare Bones, I tried to compile kernel.c and got this:
$ $CROSS/$TARGET-gcc -o $PROJECT/kernel.o -c $PROJECT/kernel.c -Wall -Wextra -Werror -nostdlib -nostartfiles -nodefaultlibs
/usr/local/cross/bin/i586-elf-gcc.exe: error while loading shared libraries: ?: cannot open shared object file: No such file or directory

I'm using "CROSS" because the person this thread said that the problem disappeared when adding the cygwin bin directory to the PATH environment variable. That didn't work in my case.
http://forum.osdev.org/viewtopic.php?f= ... 85&start=5

And he also explained what the problem was and why that solution worked, and you ignored that all-important part.

I added the cygwin bin directory to PATH and it still shows me the error.
When it says "cannot open shared object file: No such file or directory", what directory is it looking in by default?

Personally, I would stop messing arond with cygwin on Windows and use Linux as your development environment. But that's just because I'm lazy and like to do things the easy way.

I was unable to make the cross compiler with cygwin, but it worked with MinGW.

couldn't find cygwin1.dll
After adding the cygwin bin directory to my PATH the error went away

Well unless I'm setting the PATH wrong, that method didn't work. I went as far as setting the PATH for Cygwin and Windows environment variables.

use Linux as your development environment.

Do not suggest Ubuntu, I don't have an available machine to install it right now.

You can install Linux in a Virtual Machine on your Windows computer and get on with development. Or you can mess about with cygwin. Either way is fine by me.
