LDFLAGS += -Wl -Wall -lpthread -lc -ldl
LDFLAGS += -Wl -lpthread
在编译链接的时候出现了如下的错误：
gcc: error: unrecognized command line option ‘-Wl’
gcc: error: unrecognized command line option ‘-Wl’
通过gcc -v查看gcc版本如下：
root:~# gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/usr/lib/gcc/x86_64-linux-gnu/4.8/lto-wrapper
Target: x86_64-linux-gnu
gcc version 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04)
求大神帮助！

哪来的 Wl，什么意思？
#5
4L ，-Wl选项告诉编译器将后面的参数传递给链接器，如果连接器通过被编译器驱动来间接引用(比如gcc), 那所有的连接器命令行选项前必须加上前缀'-Wl'
#6
应该是 -Wl, 后面一个 逗号 吧
