Editing a line in file helloWorldApp/Makefile could help.

Replace
        USR_SYS_LIBS += expat
with
	# USR_SYS_LIBS += expat

This should work since the code makes no reference to expat library. If
the code tried to do anything with expat library, there would be compile
time problems due to apparently missing expat.h header file.

If you needed expat header files and files required for linking, you
would need to install expat-devel package (yum install expat-devel).
