实用脚本 4 -- Makefile(不同文件下的多个可执行文件or静态库编译到同一目录下)

不同文件下的多个可执行文件编译到同一目录下，这样方便观察编译结果，从而方便进程操作。使用时根据自己的需要在进行局部修改（如 链接库、目标文件等等）。

1、.bashrc 中设置编译主目录（例如）

export MKHOME=$HOME

ORACLE_HOME=/oracle/10G; export ORACLE_HOME

2、主目录中创建一个mak文件夹，文件夹中创建以下三个文件（database.mak、mkstand.mak、platform.mak）：

（1）database.mak（嵌入数据库文件编译配置选项，其中libclntsh.so为数据库中的库文件）

（2）platform.mak（编译默认选项）

3、每个需要编译生成可执行的文件夹下创建makefile文件（内容如下）

4、执行make可执行文件会生成在（BINP    =   $(MKHOME)/bin）所指定目录下 O(∩_∩)O~

5、静态库生成需要编译的文件夹下创建makefile文件和可执行文件略有不同（make一行写在 ##STATIC LIB下，有时不需要链接其他库 PRGLIBS1）如下：
