利用 autoconf 和 automake 自動生成Makefile

利用 autoconf 和 automake 自動生成Makefile

---

想起來自己寫的一些代碼，不想用IDE，還不會寫makefile。所以：

工具

autoconf automake # 沒錯就是在編譯 Protocol Buffer 時安裝的那幾個

生成流程圖一覽

具體步驟

$ cd SRC_DIR
$ autoscan
$ emacs configure.scan
$ mv configure.scan configure.ac
$ emacs makefile.am
$ aclocal
$ autoconf
$ automake --add-missing
$ ./configure
