编译时报错

[onlyJinx]

我用的是编译polarssl库那个方法，在编译polarssl库时能正常生成文件；然后也复制到ngrok-c下了，所有操作都和教程一样，在执行openwrtbuild.sh报错了，SDK的问题自己Google解决了，这个问题我搞不定，请大家提示一下哪里错了，哈哈 机器ubuntu16，编译给K2路由（mipsle）

openwrtbuild.sh里的CC=mipsel-openwrt-linux-g++我改成SDK里的g++(mipsel-openwrt-linux-uclibc-g++)也不行

[dosgo]

这个不是很简单，找不到头文件，直接把polarssl头文件复制到你sdk的include目录

[onlyJinx]

早上好~ 请问是把mbedtls-2.16.2里的全部文件复制到SDK的include里去吗？谢谢。。

[dosgo]

如果是meddtls得把config.h的常量打开来

[onlyJinx]

如果是meddtls得把config.h的常量打开来

大大有QQ交流群之类的吗？或者个人QQ之类的，加一下，哈哈，怕泄露的话那加我的925198583

[onlyJinx]

如果是meddtls得把config.h的常量打开来

常量我打开了，meddtls的编译完后生成三个文件（libmbedcrypto.a libmbedtls.a libmbedx509.a ）所以应该算2.0的吧，所以我都是按照2.0的教程操作的，所有不步骤都正常，就执行openwrtbuild.sh时报错了

[dosgo]

最重要的错误呢。。

[onlyJinx]

最重要的错误呢。。

我直接贴在下面了，麻烦看一下，已经把mbedtls-2.16.2/include里的文件都复制到SDK里的include了

那你找找sdk include有没有polarssl文件夹，没有的话就不用我说了吧

那你找找sdk include有没有polarssl文件夹，没有的话就不用我说了吧

sdk/include没有，在sdk/usr/include倒是找到一个polarssl，我把它复制到skd/include下去重新运行openwrtbuild.sh也是报错（复制ngrok-c/polarssl的也一样报错） 搜索polarssl结果如下 root@instance-1:~/op/staging_dir/toolchain-mipsel_1004kc+dsp_gcc-4.8-linaro_uClibc-0.9.33.2/incl ude# find / -name polarssl /root/ngrok-c/polarssl /root/op/staging_dir/target-mipsel_1004kc+dsp_uClibc-0.9.33.2/usr/include/polarssl

可是直接git clone的话就没有教程里的openwrtbuild.sh，只有一个V2的

那你就把1.48的拿过来用

大佬，polarssl库编译成功，我把polarssl里面的include/polarssl还有include/mbedtls 文件夹都复制到SDK/include了，常量config.h也修改了，代码是直接git clone的了，执行openwrtbuild.sh时报下面的错误，请再提示提示哪里有问题。。

[dosgo]

这个命令应该没问题，.a文件有问题，可能你是编译的linux用的.a文件，而不是用SDK编译的.a文件，记得编译polarssl的时候得吧CC 等编译器换成sdk的gcc g++等。。这样编译出来的才是交叉的.a文件，你可以执行lipo -info xx.a查看下文件的指令集

[dosgo]

如果有mips字样应该就对，

[onlyJinx]

如果有mips字样应该就对，

应该是交叉编译的才对，这是buildlib.sh内容

this build polarssl

export PATH=$PATH:'/root/op/staging_dir/toolchain-mipsel_1004kc+dsp_gcc-4.8-linaro_uClibc-0.9.33.2/bin' export STAGING_DIR="/root/op/staging_dir" make clean make CC=mipsel-openwrt-linux-uclibc-gcc CXX=mipsel-openwrt-linux-uclibc-g++ AR=mipsel-openwrt-linux-uclibc-ar RANLIB=mipsel-openwrt-linux-uclibc-ranlib

我机器换Centos7所以找不到你说的那个指令

[dosgo]

如果上步操作显示是mips的.a文件，nm --defined-only xx.a命令看下这3个文件是否有x509_crt_free,ctr_drbg_free这些符号表，如果没有，可能是版本问题，我之前用的polarssl版本是1.4X的好像，后面2.0我都没测试过了。。

[dosgo]

linux 用readelf -h xx.a吧

[dosgo]

没有linux实现不了的东西，哈哈，从内核到外层全是开源的。。唯一比较烂的就是gui

试试，没错

是不是我引用.a文件的方式有问题

[dosgo]

最后几个.a文件换下位置看下

[dosgo]

哪个.a文件提示缺少，就放哪个到最后

哪个.a文件提示缺少，就放哪个到最后

改了位置之后报错好像没有那么多了

[dosgo]

这里参照sendmsg.cpp 把udp.cpp也加上。。依葫芦画瓢

[dosgo]

整个文件，有sendmsg字样的，都得加上相同的叫udp这样的

[dosgo]

你应该大概能看懂吧，少了个udp.cpp没有编译导致的

[dosgo]

你已经踩完所有坑了，明天一定能编译好，实在不行就睡觉吧。。。

改漏了一点，但好像没有upd.o这个文件，先睡觉吧，幸苦了，哈哈

[dosgo]

你上面那行写成upd了。。应该是udp
