为iOS（设备和模拟器）构建静态库并在XCode中使用

我是XCode-/iOS开发新手（不是编程本身），我想制作一些简单的应用程序来适应它

我目前的项目是一个简单的二维码生成。对于这个任务，我想使用开源库libqrencode。 ( ) 我在以前的编码项目中没有使用开源库，但我想我理解大多数“机制”；）

到目前为止，我一直试图构建静态库并将其包含在我的XCode项目中。但是当使用库中的函数编译代码时，我会收到错误消息

第一个问题：

但是，当我将它包括在我的XCode项目中并尝试使用该库中的两个简单函数时，我得到了以下错误（实际上与上面一样的错误消息）：

问题1: 我还尝试将主机和目标设置为i686，但也不起作用（相同的错误消息）。不幸的是，我只有“i686-apple-darwin10-llvm-g++-4.2”和类似的版本，但没有“i386 xxxx…”。这是问题所在还是我选择了错误的设置

问题2: 如何检查构建库的目标是什么？bash中有特殊命令吗？ 我记得第一次构建libqrencode时，我需要获取libpng12。到目前为止，我没有使用任何命令来创建PNG，但我没有为iPhone模拟器或iPhone设备重建PNG。libpng12库是否仍然由XCode链接，这是否会导致错误

谢谢你的帮助。很抱歉发了这么长的帖子，但我想尽可能彻底。准备好了

新增信息：

我使用以下配置设置为I386构建了libpng12：

对不起，没有帮助你解决编译问题，但是看起来你有一个更大的问题：LBQReNoCK是在LGPL下授权的，很多人认为它是（）。因此，在应用程序中使用libqrencode可能会给自己带来法律风险。

好的，我终于有时间完成这个问题了。这个问题以前已经解决了，我只是使用了一个错误的include路径。可以使用以下代码成功创建库：

再次感谢DarkDust对您的帮助

谢谢你的建议。再次提醒我，我多么讨厌许可证问题：）但这应该只是（也许）未来的问题，因为一开始我并不打算在苹果应用商店发布应用程序。如上所述，我的这个部分项目的意思是“开始使用XCode”。事实上，我甚至想发布整个源代码（因为大多数工作不是我的）。但至少我现在知道，我以后再也不用考虑把它提交到AppStore了。我已经和作者核实过了，他确认libqrencode可以在bsd风格的许可下使用。如果你对此有更多的了解，我会回击他的观点，虽然环境变量看起来不错，但生成的静态库似乎无法识别。查看命令的输出

otool-hv/Users/johnny/Desktop/MyProjects/myQRencode/libqrencode/Release iphoneos/lib/libqrencode.a

，它是否在输出的第二列和第三列中列出了

ARM

和

V6

或

V7

？谢谢你的提示！否，它列出了所有条目的“X86_64”。因此，在建立图书馆时，显然存在一些错误，但为什么呢？很明显，我试图用配置定义正确的cpuytype（目标）。顺便说一句，iPhone模拟器库也是如此。@EliteTUM：这表明它不是用

arm-apple-darwin10-llvm-g++-4.2

编译的。您需要检查生成的

Makefile

（应该在变量

CC

和/或

CXX

中）@DarkDust:在

的末尾/configure…

我得到了

CC=gcc

和

CXX=/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/i686-apple-darwin10-llvm-g++-4.2

@EliteTUM:你是说在

的末尾配置
的输出吗？如果它在Makefile中，则尝试编辑它并设置
CC=/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/i686-apple-darwin10-llvm-gcc-4.2
