RT

Build the OpenWrt SDK
就能编译出来sdk，把sdk解压然后在里面make menuconfig  后出现了这个错误！！

1. <a href="mailto:jack@ubuntu:OpenWrt-SDK-ar71xx-for-linux-i686-gcc-4.6-linaro_uClibc-0.9.33.2$">jack@ubuntu:OpenWrt-SDK-ar71xx-for-linux-i686-gcc-4.6-linaro_uClibc-0.9.33.2$</a> make menuconfig

我写了测试用的helloworld，调用了pcap库，然后出现这个错误

1. install -m0755 /home/jack/OpenWrt-SDK-ar71xx-for-linux-i686-gcc-4.6-linaro_uClibc-0.9.33.2/build_dir/target-mips_34kc_uClibc-0.9.33.2/helloworld/helloworld /home/jack/OpenWrt-SDK-ar71xx-for-linux-i686-gcc-4.6-linaro_uClibc-0.9.33.2/build_dir/target-mips_34kc_uClibc-0.9.33.2/helloworld/ipkg-ar71xx/helloworld/bin/

Package helloworld is missing dependencies for the following libraries:
libpcap.so.1.3    缺少依赖库！
但是我确实是加上了啊！
package/helloworld/Makefile

1. define Package/helloworld
   
2.         SECTION:=utils
   
3.         CATEGORY:=Utilities
   
4.         TITLE:=Helloworld -- prints a snarky message
   
5.         DEPENDS:=+libpcap
   
6. endef

复制代码

1. <p>=======package/helloworld/src/Makefile</p><p>helloworld: helloworld.o
   
2.         $(CC) $(LDFLAGS) helloworld.o -o helloworld -lpcap</p><p>helloworld.o: helloworld.c
   
3.         $(CC) $(CFLAGS) -c helloworld.c -lpcap</p><p># remove object files and executable when user executes "make clean"
   
4. clean:
   
5.         rm *.o helloworld
   
6. </p><p> </p>

复制代码

都加上了对libpcap的支持！
为嘛还是找不到....
