     =================
         If you just want to build Cppcheck without dependencies then you can use this command:
-            g++ -o cppcheck -std=c++0x -include lib/cxx11emu.h -Iexternals/tinyxml -Ilib cli/*.cpp lib/*.cpp externals/tinyxml/*.cpp
+            g++ -o cppcheck -std=c++0x -include lib/cxx11emu.h -Iexternals/simplecpp -Iexternals/tinyxml -Ilib cli/*.cpp lib/*.cpp externals/simplecpp/simplecpp.cpp externals/tinyxml/*.cpp
 
         If you want to use --rule and --rule-file then dependencies are needed:
-            g++ -o cppcheck -std=c++0x -include lib/cxx11emu.h -lpcre -DHAVE_RULES -Ilib -Iexternals/tinyxml cli/*.cpp lib/*.cpp externals/tinyxml/*.cpp
