1. 进入目录
[plh@localhost build]$ cd /tmp/LwIP/contrib-2.1.0/ports/unix/lib/
[plh@localhost lib]$ mkdir build
[plh@localhost lib]$ cd build/
2.编译有两种方法
[方法1]: 默认是没有详细的编译日志和不能gdb调试的
[plh@localhost build]$ cmake ..
[plh@localhost build]$ make
[方法2]: 打印详细的编译日志和方便gdb调试
[plh@localhost build]$ vi CMakeCache.txt
CMAKE_BUILD_TYPE:STRING=Debug
CMAKE_VERBOSE_MAKEFILE:BOOL=ON
[plh@localhost build]$cmake ..
[plh@localhost build]$make clean && make
3.编译成功后的输出文件
[plh@localhost build]$ ls -al lib*
-rwxrwxr-x. 1 plh plh 442248 12月 23 11:07 liblwip.so
4.其中一条详细的编译log
