I  have to install SDCC for MSC12xx Texas Insruments family IC's .
        I am following the steps which is given in "MSC12xx Programming with SDCC".As per the guide lines I have installed CYGWIN and now I could access the GCC compiler.Next step I have to visit the website "http://sdcc.sourceforge.net" and in that I don't know how to SDCC exe for my instalation.
Can anyone give me an idea how to complete this?
once this is done have to Build SDCC from source from GCC compiler.
Thanks in Advance,
S.Suganya.
