嵌入式程式開發 萬能的Makefile檔

萬能的Makefile檔案
　
　　據作者說是萬能的Makefile檔案,好像作者是這麼說的：「我還沒有發現當給出一個源碼檔案的目錄，這個 makefile 會失敗的情況，除非依存檔案被弄亂。如果這種弄亂的情況發生了，只要輸入 `make clean" ，所有的目標檔案和依存檔案會被刪除，問題就應該被解決了。當然，最好不要把它們弄亂。如果你發現在某種情況下這 個 makefile 檔案不能完成它的工作，請告訴我，我會把它整好的。」

### Customising

# Adjust the following if necessary; EXECUTABLE is the target
# executable"s filename, and LIBS is a list of libraries to link in
# (e.g. alleg, stdcx, iostr, etc). You can override these on make"s
# command line of course, if you prefer to do it that way.

CFLAGS := -g -Wall -O3
CXXFLAGS := $(CFLAGS)
CC := g++
　
# The next bit checks to see whether rm is in your djgpp bin
# directory; if not it uses del instead, but this can cause (harmless)
# `File not found" error messages. If you are not using DOS at all,
# set the variable to something which will unquestioningly remove
# files.

# You shouldn"t need to change anything below this point.
