Sir i tried what you told me but i am still getting the same problem while cross-compiling. The binaries generated for arm are the ones which i386 tries to execute. Can you elaborate me the technique and can you also throw more light as to what changes are needed to be brougth abt in build/autoconf/config.guess, mozilla/nsprpub/build/ autoconf/config.sub, directory/c-sdk/config/autoconf/config.sub, directory/c-sdk/config/autoconf/config.guess . I am still a beginner and so i need a little more elaborate description of solution. Hope to hear from you soon.
