linux@ubuntu:~/smb/lc_smarthome$ mipsel-openwrt-linux-gcc lc_tty.c lc_tty.h main.c -lpthread -o main

会出现一下错误：

/work/openwrt/trunk/bin/ramips/OpenWrt-Toolchain-ramips-for-mipsel_24kec+dsp-gcc-4.8-linaro_uClibc-0.9.33.2/toolchain-mipsel_24kec+dsp_gcc-4.8-linaro_uClibc-0.9.33.2/bin/../lib/gcc/mipsel-openwrt-linux-uclibc/4.8.3/../../../../mipsel-openwrt-linux-uclibc/bin/ld: warning: libdl.so.0, needed by /work/openwrt/trunk/bin/ramips/OpenWrt-Toolchain-ramips-for-mipsel_24kec+dsp-gcc-4.8-linaro_uClibc-0.9.33.2/toolchain-mipsel_24kec+dsp_gcc-4.8-linaro_uClibc-0.9.33.2/bin/../lib/gcc/mipsel-openwrt-linux-uclibc/4.8.3/../../../../mipsel-openwrt-linux-uclibc/lib/libpthread.so.0, not found (try using -rpath or -rpath-link)

collect2: error: ld returned 1 exit status

解决方法：在原来基础上加上 -ldl

即：mipsel-openwrt-linux-gcc lc_tty.c lc_tty.h main.c -ldl -lpthread -o main
