xcode - Xcode 7.1 中架构 armv7 的 undefined symbol

Question

我正在使用 Vuforia 和一个名为 Mobile Movie Textures 的 Unity 插件制作游戏。当我尝试构建我的 Xcode 项目时，一切都很顺利，直到它开始链接。我从同一个库中收到一堆错误，说它无法识别符号。

    Undefined symbols for architecture armv7:
  "_oc_idct8x8_arm", referenced from:
      _oc_state_frag_recon_arm in libtheorawrapper.a(armstate.o)
      _oc_state_accel_init_arm in libtheorawrapper.a(armstate.o)

      _oc_huff_tree_unpack in libtheorawrapper.a(huffdec.o)
      _oc_quant_params_unpack in libtheorawrapper.a(dequant.o)
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我可以让 armv7 arch 的设备不兼容，但它们占荷兰市场的 55%。

我不知道如何解决这个问题，你们能解决吗？

当前版本插件中的库 libtheorawrapper.a 已损坏，不包含所有需要的符号。

如果要使用该插件，则必须重新编译库。
为此，您需要结帐 this repository
.

然后编辑这个文件:
MMTPlugin/build/XCode/theorawrapper.xcodeproj/project.pbxproj
第 134 和 144 行的替换

/Users/dan/Documents/MobileMovieTexture/

使用您克隆 repo 的路径(例如):

/Users/MyUser/Code/git/MobileMovieTexture

然后，您可以使用 XCode 打开该项目并重新编译该库。

生成的文件将放置在:

MMTUnity/Assets/Plugins/iOS/libtheorawrapper.a

您应该将该文件复制到您的统一插件文件夹中:

Assets/Plugins/iOS/libtheorawrapper.a
