aws-cpp-sdk-example1 broken ?

[bu2]

Hi,

I can't wait to build some C++ tools with your sdk, but right now I fail to build the example:

I am building on OS X Yosemite, with CMake (3.3.1) and Clang (Apple LLVM version 6.1.0 (clang-602.0.53) (based on LLVM 3.6.0svn).

And I get undefined symbols from the linker:

$ CPLUS_INCLUDE_PATH="../../aws-cpp-sdk-core/include:../../aws-cpp-sdk-dynamodb/include:../../aws-cpp-sdk-cognito-identity/include" LIBRARY_PATH="../../build/aws-cpp-sdk-core:../../build/aws-cpp-sdk-dynamodb:../../build/aws-cpp-sdk-cognito-identity"  make

It seems there is a little mismatch between version of the example and version of the SDK where, I believe, the code has been refactored to support custom memory allocator:

• Example for the first error:

The linker is looking for:

Aws::Auth::ProfileConfigFileAWSCredentialsProvider::GetAccountIdForProfile(std::__1::basic_string<char, std::__1::char_traits<char>, **std::__1::allocator<char> > const&**)

But libaws-cpp-sdk-core.dylib defines:

Aws::Auth::ProfileConfigFileAWSCredentialsProvider::GetAccountIdForProfile(std::__1::basic_string<char, std::__1::char_traits<char>, Aws::Allocator<char> > const&)

I hope to be able to provide a fix soon, by the way is there any roadmap for aws-cpp-sdk-samples ?

Best regards.

Those samples have been touched in months. I'd just disable them and
rebuild. I'll have a look when I get to the office.

It looks like when the sample is building, the macro
-DAWS_CUSTOM_MEMORY_MANAGEMENT is not defined.

Thanks Jonathan !

I have just added:

add_definitions(-DAWS_CUSTOM_MEMORY_MANAGEMENT)

in the CMakeLists.txt of the example project... and it build.

PS: definitely waiting for more examples :-)

Regards.

[JonathanHenson]

So, if you build it in the context of the entire project, (meaning add_subdirectory from the master cmake file), that will already be there. If you build it individually, or via your own build system, it will need to be added.

I would not add it to the cmake file in our repo, because it only uses that macro when custom memory management is enabled.

[JonathanHenson]

With regards to further examples. The integration tests, can show you how to use the low-level SDKs as well as higher-level utilities such as the TransferManager.

That example, if I remember correctly, was us playing around with trying to implement something to the document model dynamodb apis similar to the C# and Java sdks.

[bu2]

Ok I got it.

I just realised that the example is built with the build of the main SDK on Windows only (/CMakeLists.txt, line 153).

From my point of view you can close the issue.

Regards.
