如何成功将ImageMagick集成到iOS中？

Question

我目前有一个链接器错误，大约有44个引用引用了x86_64体系结构的未定义符号。 他们都是来自所以我试图寻找解决方案，以“为架构x86_64的未定义符号libmagickcore.a”我已经看到了这里的解决方案集成文件“libMagickCore.a” 适用于建筑x86_64的ImageMagick的Mac上的狮子未定义的符号 ，其解决了类似的Mac Lion上的问题。 我也曾在ImageMagick板上查看过类似的问题。 我发现的线程和Stack Overflow链接似乎在讨论包括或明确排除X11库。

我试图在构建设置下将“ -lX11”添加到“其他链接器标志”，但最终出现“找不到-lX11的库”。 因此，我还尝试将libX11.dylib从/ opt / X11 / lib拖到我的XCode项目中，无济于事。 对于ImageMagick板上类似问题的建议是使用“ --without-wmf”“-without-x11”标志，但是我不知道要在没有编译器错误的情况下将其添加到构建设置的哪个键/值对中说“不支持的选项”。

这些是链接器错误：

通过转到“构建阶段”并将“二进制链接与库”添加到项目中，可以将“ libxml2.2.tbd”添加到项目中，从而解决了该问题。
