Build fails with xcode 9.3 (Beta)

[skathiresan]

Description:

Building Fuzi with xcode 9.3 fails with error Redefinition of module 'libxml2' [ I think the issue is because of the file module.modulemap. The error should go way by renaming it to something else like Fuzi_module.modulemap.]

• Expected behaviour: Successful Build without errors.

• Actual behaviour: Build Failure.

  Environment

• Package Manager:

  • [ ] Carthage, version:
  • [X] CocoaPods, version:1.4
  • [ ] Manually

• Fuzi version: Latest (2.0.1)

• Xcode version: 9.3

How to reproduce:

Just include Fuzi to a new project using cocoapods and try building with xcode 9.3 Sample -> Fuzi_xcode93.zip

Same issue with Xcode 9.3

Maybe it's the same as https://github.com/tid-kijyun/Kanna/issues/176

[dan12411]

same issue as https://github.com/tid-kijyun/Kanna/pull/177, I temporary change the "libxml2" to "libxmlFuzi" locally, and build without error

I think the error is caused by Redefinition. Xcode 9.2 does not have the modulemap. Xcode 9.3 does have it. May simply removing repeated modulemap in Fuzi resolve this, instead of renaming it?

@banjun Not work for me, you can try and PR.

Use LiKui(https://github.com/ChaselAn/LiKui) to fix this problem

[cezheng]

Sorry folks I've been really busy lately and I'm thinking exactly what @banjun suggests. @SuperY what error did you get when you removed the modulemap?

@cezheng same error with xcode 9.3

Hi @cezheng , When I renamed libxml2 to libxml2Fuzi, I got this error:

Could you help me to solve this problem?

[banjun]

I have removed the modulemap in #83. Feedbacks are helpful, @cezheng & folks here!

@lovexiaov Undefined symbols is caused by missing -lxml2. We should eventually link with libxml2 in any way.

[SuperY]

@banjun You are right. Need add '-lxml2' to Linker Flags. @cezheng It's time to merge....

[lovexiaov]

@banjun @SuperY Thanks, add -lxml2 to Linker Flags solved my problem.
