debian RT-AC68U 交叉编译链 编译 ChinaDNS 失败

[xzm1006]

我git clone完后使用./autogen.sh && CC=arm-uclibc-linux-2.6.36-gcc CXX=arm-uclibc-linux-2.6.36-g++ AR=arm-uclibc-linux-2.6.36-ar RANLIB=arm-uclibc-linux-2.6.36-ranlib ./configure --host=arm-uclibc-linux --enable-static && make进行编译

结果报错如下：

arm-uclibc-linux-2.6.36-gcc -DHAVE_CONFIG_H -I. -I.. -g -O2 -MT chinadns.o -MD -MP -MF .deps/chinadns.Tpo -c -o chinadns.o chinadns.c
mv -f .deps/chinadns.Tpo .deps/chinadns.Po
arm-uclibc-linux-2.6.36-gcc -g -O2 -static -o chinadns chinadns.o -lresolv
chinadns.o: In function `hostname_from_question':
/root/ChinaDNS/src/chinadns.c:727: undefined reference to `__ns_parserr'
chinadns.o: In function `should_filter_query':

chinadns.o: In function `dns_handle_local':

请问应该如何解决？本来想@ /t/124550 76L的szpunk，但是他似乎很久没上了

正确的交叉编译配置应该是 ./configure --host=arm-uclibc-linux-2.6.36 --enable-static，
不要再指定 CC=... 之类的。错误原因似乎是没有找到 libresolv，你应该把 configure 的 log 贴出来。

给个临时解决方案（不一定可行）：
cd src
arm-uclibc-linux-2.6.36-gcc -DHAVE_CONFIG_H -I. -I.. -g -O2 -MT chinadns.o -MD -MP -MF .deps/chinadns.Tpo -c -o chinadns.o chinadns.c -lresolv

[xzm1006]

@XiaoxiaoPu 谢谢你给出临时解决方案，我运行后不报错了，但是我不知道下一步应该做什么，请原谅我编译小白
因为我按照教程用该交叉编译配置成功编译了ss，并且放入路由器可运行，你的交叉编译配置之前已试过，成功生成了文件，但出现报错如下：
chinadns.o: In function `resolve_dns_servers':
/root/ChinaDNS/src/chinadns.c:326: warning: Using 'getaddrinfo' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking

放入路由器运行出现报错如下：
RT-AC68U-D9F8:/jffs# ./chinadns -m -c chnroute.txt
./chinadns: line 6: syntax error: unexpected word (expecting ")")
RT-AC68U-D9F8:/jffs# ./chinadns: line 1:ELF : not found

[XiaoxiaoPu]

有问题的原因主要就是 chinadns 用到了 libresolv，可能你的交叉工具链里没有 libresolv 的静态版本，你试试把 --enable-static 去掉。或者试试这个内嵌了 libresolv 的版本： https://github.com/XiaoxiaoPu/ChinaDNS

[yushiro]

lz，你是按照哪篇教程交叉编译SS的？我也是Ac68U，正需要～

[xzm1006]

@LazyZhu 感谢~试了能运行~话说18KB这么小……我以为路由器只能静态编译运行

[xzm1006]

@XiaoxiaoPu 试了编译你修改的版本，编译出来了！的确是缺少了libresolv，万分感谢！

[xzm1006]

@yushiro 教程可以参考/t/165064

[xzm1006]

@LazyZhu 能请教你是用什么交叉工具链编译的吗？发现我之前编译的ss-tunnel，放在路由器运行出现Segmentation fault错误……抓狂了

@XiaoxiaoPu
请问，你的内嵌libresolv的版本的chinadns能再次分享吗？
@LazyZhu
请问您是如果动态编译这个18k的chinadns的呢？能分享下吗？

[XiaoxiaoPu]

@kdrx 动态链接能运行就没必要静态链接了

[kdrx]

@XiaoxiaoPu
我不是需要静态链接啊，静态连接后能运行的，但是体积太大。
我是需要你这种内嵌libresolv的版本的动态链接编译。
我官方源码用 arm-linux-gcc 交叉编译动态链接后，目标机器ac68u提示缺少libresolv.so。
而lazyzhu的动态链接版本能在asus 68u 正确运行，而我用ldd观察，发现他根本就没有链接libresolv.so库，可能也是源码中嵌入了libresolv中的相应函数。

@kdrx 代码不在工作的电脑里，晚上给你

[kdrx]

@XiaoxiaoPu 好的，谢谢你！发我邮箱吧： [e-mail]

@kdrx @LazyZhu @XiaoxiaoPu 您好！我交叉编译也遇到一些错误！是编译 tomato mips 平台的

可以直接下载 OpenWRT-SDK 来编译的:
http://downloads.openwrt.org/chaos_calmer/15.05-rc3/bcm53xx/generic/OpenWrt-SDK-15.05-rc3-bcm53xx_gcc-4.8-linaro_uClibc-0.9.33.2_eabi.Linux-x86_64.tar.bz2

[qq674949301]

@LazyZhu 好的！ brcm 53xx 的不是 ARM 平台的？

[qq674949301]

@LazyZhu 我的是 BRCM 4706,应该属于 BCM 47XX 的吧？

[qq674949301]

@还有 OpenWrt SDK 编译的放在 tomato 能运行吗？
