Build error

[zhanglianyu0911]

Hi @bwasti , @orionr When I clone I tried to build this demo, I got this error, where I am I missing when I configure it? Should I add more in gradle? My gradle version is 3.0.1

I also got the same error. I can see that the error is in the native compilation phase, in which there are a number of messages about undefined reference to the C++ std lib. I guess the prebuilt caffe may need to be rebuilt with Android libc++ STL?

[YiLin-Chen]

same issue...

[YiLin-Chen]

I found that it is an issue from latest NDK version. I solved the problem by downgrading the NDK version. Check this https://groups.google.com/forum/#!topic/android-ndk/3iKT-kLEGpY

[zhanglianyu0911]

@YiLin-Chen You are right about that. I just downgraded NDK version as 15. Then it built successfully !

[detectRecog]

@zhanglianyu0911 Hey, bro. Can you give a list of configurations? After downgrading the NDK version to 15, I still get this error:

兄弟可以把你project的配置比如（NDK版本，ide版本，gradle版本）之类的配置发一下么

[codestar12]

I got the same error are detectRecog after downgrading to NDK 15. I also tried NDK 16 and got the same message. maybe it is a problem with setting up paths while downgrading? All I did was delete the ndk-bundle file in Andriod/Sdk/ and unzip the new ndk and rename it to ndk-bundle

[luisvega23]

Hi ! I tried downgrading to NDK 15 too, but i still got this error:

I'm ussing the lastest AndroidStudio and NDK15. My SO is Ubuntu 16.04.

[jorge-pessoa]

@luisvega23 Clean and rebuild your project for the new NDK version and it should work. Your automatically generated .ninja file was done so using a different NDK version

[luisvega23]

@jorge-pessoa I did it and work ! Thanks you

[winter1988]

my os is mac os and what i have done is to replace files in ndk-bundle with android-ndk-r15c
it work for me !!!!
