Cannot locate symbol "rand" - ndk-r10d android-21

#1

Hi,

I have below error when starting cpp-tests:
dlopen("/mnt/asec/org.cocos2dx.cpp_tests-1/lib/libcpp_tests.so") failed: dlopen failed: cannot locate symbol “rand” referenced by “libcpp_tests.so”

cocos2dx-3.3, ndk-r10d, android-21
cpp-tests was compiler with cocos compile -android

How to fix it properly?
I read something about new C library in Android-L.

what compiler?

#3

Choose android-19 and it will work.
Do you really need android-21? Because if you do, you’re going to have trouble getting it working on Android 5.0 AND Android 4.x and lower…

#4

The NDK platform target should equals to your minSdkVersion

Thank you for answer.

android-19 fixed issue.
cocos compile -android --ap 19

Will cocos2dx work on Android 5.0 with --ap 19?

Hello,

I got similar problem. I’m using ndk-r10e and Android api 22, on Windows environment.
My question is whether there is a workaround without forcing me to switch to api 19?
