UE4 android packaging error

[leehh]

Hello.
First, I am sorry that I am not good at English.

I'm using the Unreal Engine 4 to create a mobile game for Android OS.

I want to use AWS Gamelift.

I succeeded in playing PC packaging.
I failed the android.

Look at the error log and help.

Plugins/GameliftSDK/Source/awsCore/Public\aws/core/utils/memory/stl/AWSAllocator.h:67: error: undefined reference to 'Aws::Malloc(char const*, unsigned int)'

Source/testdedi/AwsSdkManager.cpp:23: error: undefined reference to 'Aws::Client::ClientConfiguration::ClientConfiguration()'

C:/NVPACK/android-ndk-r12b/sources/cxx-stl/gnu-libstdc++/4.9/include\ext/new_allocator.h:127: error: undefined reference to 'Aws::GameLift::GameLiftClient::GameLiftClient(Aws::Client::ClientConfiguration const&)'

Hi, can you fill the following field so we can have a background story. Have you used an android-tool-chain.cmake?

What platform/OS are you using?

What compiler are you using? what version?

What's your CMake arguments?

Can you provide a TRACE level log? (sanitize any sensitive information)

[leehh]

i am sorry....
I am a beginner.
Should I use android-tool-chain.cmake?

What platform/OS are you using?
ue4 android

What compiler are you using? what version?
vs2015

What's your CMake arguments?
cmake .. -G "Visual Studio 14 2015 Win64"
and ALL_BUILD.vcxproj -> all build
I made ue4 awscpp plugin thirdparty...
and load lib, dll

Can you provide a TRACE level log? (sanitize any sensitive information)

Oh, you were trying to build aws sdk a dynamically loadable plugin? And you have successfully done that, but the error happened when you were trying to use it. Do I understand right?

[leehh]

Yes, that’s right.
I first found out if it was in the PC environment.
And then I tried to figure out whether Android was possible.
But that's an error.

Am I wrong?
It's hard because there's no example.

Please explain it briefly.

[singku]

Did you define USE_DLL_SEMANTICS and USE_IMPORT_EXPORT in your build script?

[leehh]

I'm using both.
Should CUSTOM_MEMORY _ MANAGEMENT be turned off?
Or is there another way?

-G "Visual Studio 14 2015 Win64"
creates a Win64 build which won't work.

Have a look at the cmake option related to Android within the SDK's readme.

You might want to start with the following command line and iterate:

cmake -G "NMake Makefiles" -DTARGET_ARCH=ANDROID ...

You'll need to run this from an NMake aware command prompt. One of the Visual Studio Command Prompts should work. You'll also want to limit the project generation to just the services you want to use (-DBUILD_ONLY=...) . Last time I checked, it took hours to build the whole SDK for Android on Windows.

Here's an old issue where someone was building for Android on Windows that might have some additional insight:

#230

Thank you Bret.
