M-x compile RET C-a C-k make -C /home/chengqi/src/abc/Makefile all RET

next time you can just do:

M-x recompile RET

ECB is the most complete package to do that.

Otherwise, there are also tools such as tags (use etags(1) to build a
TAGS index, and use M-. to jump to the definition(s) of a symbol,
M-TAB to complete a symbol, etc).

Put this in your Makefile:

tags etags:
        find $(SRCDIR) \( \( -name \[#.]\?\* -prune \) \
                          -o -name \*.h -o -name \*.c  \
                          -o -name \*.hh -o -name \*.hxx -o -name \*.cc -o 
-name \*.cxx \) \
                          -print \
         | while read f ; do echo $$f ; etags -a -o $(SRCDIR)/TAGS $$f ; done

M-x compile RET C-e tags RET

and then type or move after the name of a function, and type M-.
