    I have search over the google and forums. I have installed icu and other dependencies properly.

    Please help me to compile the Qt source successfully.

    Thanks

  • Hi,

    I have installed ICU for i386 in my ubuntu machine and added environment PATH. Also, I have used -icu in configure. Then the error was resolved.
