linux下C/C++编译脚本。本源码封装makefile系统的格式的命令，只需对源码进行少量修改（修改make/head.mk）便可以进行交叉编译。不进行交叉编译的同学可以直接修改makefile文件里面的字段（字段意义在对应文件内有说明）即可。本系统支持多级目录递归编译。-C/C++ Linux compiler scr ipt. This source code package makefile system format command, simply a small number of source code changes (modified make/head.mk) can be cross compiled. The students who do not cross compile can directly modify the field in the makefile file (the meaning of the field can be described in the corresponding file).. The system supports multi-level directory recursion compiler.
