如何将ImageMagick成功集成到iOS中？

标签： ios xcode linker imagemagick

我目前有一个链接器错误，大约44个引用x86_64架构的未定义符号。所有这些都来自一个集成文件＆＃34; libMagickCore.a＆＃34;所以我试图为架构x86_64 libmagickcore.a＆＃34;＆＃34;未定义的符号搜索解决方案。 我在这里看到了一个解决方案Undefined symbols for architecture x86_64 ImageMagick on Mac Lion，它解决了Mac Lion上的类似问题。我也看过ImageMagick板上的类似问题。我找到的线程和Stack Overflow链接似乎谈论包含或明确排除X11库。

我试图添加＆＃34; -lX11＆＃34; to＆＃34;其他Linker Flags＆＃34;在构建设置下，但我最终找不到＆＃34;找不到-lX11的库。＆＃34;因此，我也尝试将libX11.dylib从/ opt / X11 / lib拖到我的XCode项目中无济于事。关于ImageMagick板上类似问题的建议是使用＆＃34; - without-wmf＆＃34; ＆＃34; - 无需-X11＆＃34;标志，但是我不知道在没有编译器错误的情况下添加它的构建设置的哪个键/值对＆＃34;不支持的选项。＆＃34;

论文是链接器错误：
