如果你在iOS上使用curl碰到不能编译的问题，请呼叫我

Cocos2d-x
#21

改哪个设置啊， 求指点

#22

hello～ 麻烦问下，我这边cocos2dx 版本的2.2.6 ，在arm64下编译，其他问题都已解决，但是libcurl死活链接不过去，直接用3.x版本的头文件＋libcurl.a和libcurl_arm64.a，报错说
Undefined symbols for architecture x86_64:
“_opendir$INODE64”, referenced from:
_OPENSSL_DIR_read in libcurl.a(o_dir.o)
“_readdir$INODE64”, referenced from:
_OPENSSL_DIR_read in libcurl.a(o_dir.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

如果用网上的一个 ioscurl-7.40.0.tar.gz ，它本身编译运行都没问题，armv7 7s，64都ok，但是我移到cocos2dx里就会报错

然后我下载了curl源码，再不用arch直接make出不同架构的静态库，添加到工程中，又说新的头文件报错：
/*

  • Verify that the size previously defined and expected for long
  • is the same as the one reported by sizeof() at compile time.
    */

typedef char
curl_rule_01
;

/*

  • Verify that the size previously defined and expected for
  • curl_off_t is actually the the same as the one reported
  • by sizeof() at compile time.
    */

typedef char
curl_rule_02
;

有点崩溃，请问如何解决？
另求楼主QQ

#23

分别为i386，x86_64，armv7，armv7s，arm64这些cpu架构编译静态库和生成头文件，
然后把所有静态库用lipo合并成一个静态库。

上面这个是怎么做的啊？？？？求指导

#24

请问你问题解决了吗？？？？我也遇到一样的问题，从网上下的ioscurl-7.40.0.tar.gz，替换掉就出现Undefined symbols for architecture x86_64

#25

xcode-select --install，执行这个命令即可

#26

楼主,我现在是Xcode7,iOS9.翻了N多的教程,没弄成功,麻烦楼主发一份给我~983174628@qq.com
谢谢啦~Xcode高一点的版本没问题吧?

#27

别用百度，用谷歌。 ios curl 第一个就是开源库。运行下，自动编译最新的库。直接用就行。

https://github.com/biasedbit/curl-ios-build-scripts

有小问题，看issues。

#28

这个时间有点久远了,不过能用就好~我照着楼主大神的方法做了,结果出现如同楼主那样的错误,还在调试中…

#29

刚刚看了一下,这个是更新到最新的.我等下试试~

#30

#31

请查看： http://www.cocoachina.com/bbs/read.php?tid-456515.html

#32

https://github.com/biasedbit/curl-ios-build-scripts我使用github上的这个脚本自动编译以后，引入.a 和includ头文件之后出现libcurl linker command failed with exit code 1的错误。困扰很久了…

#33

对啊，之前好像有一个简单方法，不需要每个编译的，忘了，这个方法不是很靠谱，xcode不能用旧的编译

而且mac自带curl因为可以通过curl "http://github.com"直接下载项目的

#34

我也不会编译多个curl，我现在想到的方法就是直接引用源码
如果有编译curl _x86_64 | arm64 | i386 的方法，请帖出来
