I simply want to run an executable from the command line, ./arm-mingw32ce-g++, but then I get the error message,

bash: ./arm-mingw32ce-g++: No such file or directory

I'm running Ubuntu Linux 10.10. ls -l lists

-rwxr-xr-x 1 root root  433308 2010-10-16 21:32 arm-mingw32ce-g++

Using sudo (sudo ./arm-mingw32ce-g++) gives

sudo: unable to execute ./arm-mingw32ce-g++: No such file or directory

I have no idea why the OS can't even see the file when it's there. Any thoughts?

This error can mean that ./arm-mingw32ce-g++ doesn't exist (but it does), or that it exists and is a dynamically linked executable recognized by the kernel but whose dynamic loader is not available. You can see what dynamic loader is required by running ldd /arm-mingw32ce-g++; anything marked not found is the dynamic loader or a library that you need to install.
