如何将C ++静态库正确包含到iOS项目中

Question

I have a project which contains C++ static library (mylib.a), header for it (mylib.h) and objc class which use functions of this library ( .h/ .m). I'm trying to copy this files to another project but every time I'm getting linking error.

Undefined symbols for architecture armv7
_ClassNameFromLibrary
referenced from:
      -[LibraryUserClass init] in LibraryUserClass.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

This library works correctly in another project. I tried to copy all setting from working project and it doesn't help.

Answer 1

Try to add libxml2.dylib and libz.dylib In Link Binary With Libraries.

If that does not work, please refer this question answer: Undefined symbols for architecture armv7

Answer 2

通过改变文件固定myclass.m到myclass.mm
