我正在用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,一切顺利,直到它开始链接.我从同一个库中得到一堆错误,说它不能识别符号.

我可以让装备与armv7拱不兼容,但它们占荷兰市场的55％.

我不知道如何解决这个问题,你们中有谁能想出来吗？

解决方法

当前版本的插件中的库libtheorawrapper.a已损坏,并且不包含所有必需的符号.

如果要使用该插件,则必须重新编译该库.
要做到这一点,你需要结帐this repository
.

然后编辑此文件：
MMTPlugin /编译/的XCode / theorawrapper.xcodeproj / project.pbxproj
第134和144行的替换

/Users/dan/Documents/MobileMovieTexture/

用你克隆回购路径的路径(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库.

生成的文件将放在：

MMTUnity/Assets/Plugins/iOS/libtheorawrapper.a

你应该将该文件复制到unity插件文件夹：

Assets/Plugins/iOS/libtheorawrapper.a
