i have a main.cpp in top directory and some modules in sub-directories. each
module compiled as a .a library and the main.cpp staticly linked with those
.a's. it work no problem for compile/link.

but, now i want to add gprof capability to the resulting executable. so i add
'-pg' to _CXXFLAGS for each modules's as well as to the main
program's  automake reported no error and produced an
executable. but after i run the executable, there is no .out profile
generated. so i think '-pg' flag has not take effect.

what's wroing with my steps?  thanks for your help.
