Android运行报错 about logan

[Richard-Cao]

你是自己本地编译的？

[z396431245]

是的

[Richard-Cao]

用ndk r16试试呢？

[z396431245]

ndk r16也试过了 也是报一样的错

[Richard-Cao]

电脑系统是？

[z396431245]

Windows 10

[Richard-Cao]

拉最新的代码编译试试？

[haizhiyun]

这个问题怎么解决，有解决的吗

[Richard-Cao]

这个问题我本地复现不出来……你们的环境有更详细的信息吗？

[haizhiyun]

int fd = open(_filepath, O_RDWR | O_CREAT, S_IRUSR | S_IWUSR | S_IRGRP | S_IWGRP)
我用的是13 找机会试试16 我们的环境 O_CREAT, S_IRUSR | S_IWUSR | S_IRGRP | S_IWGRP 没有这几个变量的申明处 O_RDWR | O_CREAT 是在fcntl.h 中申明的 这个文件找不到后面那几个的申明，不知道你的环境中，那几个常量是哪里申明的呢

[haizhiyun]

换16 好了 ~ 定义在stat.h 文件中

[Richard-Cao]

@haizhiyun Fine

[bright999]

我也碰到这个问题了，换成ndk16，还是那样，有其它解决办法的么？

windows系统吗 @bright999

[bright999]

@Richard-Cao 是的 win7 64位 使用的是android studio 3.0 beta 5

[Richard-Cao]

Windows机器我确实没试过…… @bright999 应该是和Windows的ndk有关系

[a1850524995]

所以问题解决了吗，内心崩溃搞了一天了。。。。同Windows

好的明天用我的Mac试一下。。。。谢了

[a1850524995]

除了降低NDK的版本外，降低OpenCV的版本同样有效，换回3.4.5版本就好了
