&gt;&gt;&nbsp;on&nbsp;both&nbsp;Windows&nbsp;and&nbsp;Ubuntu.

&gt;&gt;&nbsp;Please&nbsp;help,&nbsp;thanks&nbsp;in&nbsp;advance.

&gt;&gt;&nbsp;Fatal&nbsp;error:&nbsp;C3900U:&nbsp;Unrecognized&nbsp;option&nbsp;'-fPIC'.

&gt;&gt;&nbsp;

&gt;&gt;&nbsp;My&nbsp;question:

&gt;&gt;&nbsp;I&nbsp;don't&nbsp;know&nbsp;why&nbsp;such&nbsp;compiling&nbsp;options&nbsp;have&nbsp;been&nbsp;added&nbsp;automatically&nbsp;by

&gt;&gt;&nbsp;CMAKE?&nbsp;armcc&nbsp;doesn't&nbsp;recognize&nbsp;it.

&gt;&gt;&nbsp;

&gt;&gt;&nbsp;2.&nbsp;On&nbsp;Windows&nbsp;XP.

&gt;&gt;&nbsp;My&nbsp;Question:

&gt;&gt;&nbsp;I&nbsp;have&nbsp;set&nbsp;CMAKE_C_COMPILER&nbsp;already,&nbsp;why&nbsp;does&nbsp;it&nbsp;still&nbsp;can't&nbsp;find&nbsp;it?

&gt;&gt;&nbsp;set&nbsp;CMAKE_CXX_COMPILER&nbsp;to&nbsp;a&nbsp;valid&nbsp;compiler&nbsp;path&nbsp;or&nbsp;name.

&gt;&gt;&nbsp;

&gt;&gt;&nbsp;

&gt;&gt;&nbsp;CMakeLists:

&gt;&gt;&nbsp;

&gt;&gt;&nbsp;cmake_minimum_required(VERSION&nbsp;2.8)

&gt;&gt;&nbsp;PROJECT&nbsp;(HELLO)

&gt;&gt;&nbsp;

&gt;&gt;&nbsp;SET(CMAKE_CXX_COMPILER&nbsp;&nbsp;${CMAKE_C_COMPILER})

&gt;The&nbsp;above&nbsp;cross&nbsp;compiler&nbsp;settings&nbsp;should&nbsp;occur&nbsp;before&nbsp;the&nbsp;PROJECT()&nbsp;statement&nbsp;
