Can not get Codesourcery work

Hi everyone,
I am new to this forum as well as new to ARM development.
I have lpc2106 and I have some example projects from cmucam3 and WinARM. I wanted to compile the programs.

So, I installed cygwin and latest version of Codesourcery Lite for windows. I have installed both of them.Then I tried to test my installation by arm-none-eabi-gcc -v and the output is Using built-in specs.

Then I tried to compile the example downloaded from cmucam.org. I navigated to projects folder and typed make clean. This command was successful. But then I gave command make and it shows as following-

And I don't understand any of this. Just understand things are going wrong.

Can you please help me. I can't figure anything out. My OS is Windows 7 and it is a 64bit version. If you need anymore information just let me know.

Please help me.

***Sorry for my bad English.

    It looks like you have a couple of problems ...

    Some of the functions you are calling are expecting an argument of "uint8_t *", but you are passing them a "char *", even though both of these are probably byte width they are technically different types in C. By default the GNU compiler now uses strict type aliasing when running in C99 mode, so it will error if you alias two types like you have here. You can disable this using the "-fno-strict-aliasing" compiler option, but it is probably better to fix your code to use the data types the function is expecting.

    Secondly you seem to be missing the declation of "EBADFD"; you probably need to include the correct header to pull in this define.
