3.8打包安卓提示：error: no template named 'unary_function' in namespace 'std';

Creator 3.x

使用cocos自带的“生成”会提示该错误

又按照文档使用andorid studio打开·proj·目录后，进行build也提示：

error: no template named 'unary_function' in namespace 'std'; did you mean '__unary_function'?
    struct hash_base : std::unary_function<T, std::size_t> {};
                       ~~~~~^~~~~~~~~~~~~~
                            __unary_function

我搜索到了都是关于xcode打包ios的信息，没有找到安卓的问题，请问有什么好的解决办法吗？或者更换cocos 版本？

这是配置，都没怎么选，andorid api选的是29

俺3.7 打包也遇到这个问题 题主解决了吗

#4

我也是啊，引擎组有没有临时解决方案呢？等3.8.2太慢了

#5

3.7.0的也是这个问题

#6

3.8打包同问题…

#7

这个符号是引擎底层里面定义的, 我直接去引擎目录把这个符号改了。打包倒是正常了， 目前到没发现问题。只是如果需要打包其他原生可能还需要再改回来…

C:\ProgramData\cocos\editors\Creator\3.8.0\resources\resources\3d\engine\native\cocos\base\std\hash

struct hash_base : std::__unary_function<T, hash_t> {}

#8

我改了以后，还是不行，别的地方又出问题了

#9

NDK别用那么新的，用 android-ndk-r25c，就足够了。用最新的NDK，的确会出现这个问题。

#10

什么都不要改，就用老的NDK就行，然后build.gradle里指定一下NDK的版本就行。
