How to successfully integrate ImageMagick into iOS?

Question

I currently have a linker error, roughly 44 references to undefined symbols for the architecture x86_64. All of them are from an integrated file "libMagickCore.a" so I attempted to search for solutions to "undefined symbols for architecture x86_64 libmagickcore.a" I have seen a solution here Undefined symbols for architecture x86_64 ImageMagick on Mac Lion which addresses a similar issue on Mac Lion. I have also looked on ImageMagick boards for similar issues. The threads that I found and the Stack Overflow link seem to talk about including or explicitly excluding an X11 library.

I attempted to add "-lX11" to "Other Linker Flags" under build settings, but I end up with "library not found for -lX11." Because of this, I also tried dragging libX11.dylib from /opt/X11/lib into my XCode Project to no avail. Suggestions for similar issues on the ImageMagick boards are to use a "--without-wmf" "--without-x11" flag, but I do not know which key/value pair of the build settings to add that to without a compiler error saying "unsupported option."

Theses are the linker errors:

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。
