Statically link Hello S3 App with sdk libraries

[prateekpinisetti]

Hello, I am following the guide here: https://docs.aws.amazon.com/sdk-for-cpp/v1/developer-guide/build-cmake.html and am trying to statically link the c++ sdk libraries, as I intend to run the binary on a platform where I know the shared libraries will not be available (and I am additionally unable to install them on that platform). Compilation works fine with shared libraries. How can I go about doing this in the CMakeLists.txt file? I have compiled the SDK with the ENABLE_SHARED_LIBRARIES=OFF options, and I have confirmed that the aws*.a files exist under /usr/local/lib64. Right now everything in my CMakeLists.txt and main.cpp files are the same as in the example. Any help would be greatly appreciated!

I have compiled the SDK with both -DFORCE_SHARED_CRT=OFF and -DBUILD_SHARED_LIBS=OFF as well.

When I try to compile main.cpp I run into the following error:

/var/mnt/data/prateekpinisetti/toolchain/v2/bin/../lib/gcc/x86_64-pc-linux-gnu/10.3.0/../../../../x86_64-pc-linux-gnu/bin/ld: CMakeFiles/app.dir/main.cc.o: in function `Aws::Endpoint::DefaultEndpointProvider<Aws::Client::GenericClientConfiguration<true>, Aws::Endpoint::BuiltInParameters, Aws::Endpoint::ClientContextParameters>::OverrideEndpoint(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)':

Can you trying cleaning up your user directory before trying to do a fresh static install? I wasn't able to reproduce the error that you are seeing and I ran the following commands:

mkdir build_static
cd build_static
cmake .. -DBUILD_ONLY="s3-crt;s3" -DCMAKE_BUILD_TYPE=Debug -DFORCE_SHARED_CRT=OFF -DBUILD_SHARED_LIBS=OFF
make
make install
cd ..
mkdir sdk_static_test
cd sdk_static_test
vim CMakeLists.txt
vim main.cpp
mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Debug
make
./sdk_static_test

CMakeLists.txt

cmake_minimum_required(VERSION 3.21)
project(sdk_static_test)
set(CMAKE_CXX_STANDARD 23)
find_package(AWSSDK REQUIRED COMPONENTS s3)
find_package(ZLIB QUIET)
add_executable(sdk_static_test main.cpp)
set_compiler_flags(${PROJECT_NAME})
set_compiler_warnings(${PROJECT_NAME})
target_link_libraries(${PROJECT_NAME} ${AWSSDK_LINK_LIBRARIES})

main.cpp

#include <aws/core/Aws.h>
#include <aws/core/utils/logging/LogLevel.h>
#include <aws/s3/S3Client.h>
#include <iostream>

using namespace Aws;

int main()
{
    //The Aws::SDKOptions struct contains SDK configuration options.
    //An instance of Aws::SDKOptions is passed to the Aws::InitAPI and
    //Aws::ShutdownAPI methods.  The same instance should be sent to both methods.
    SDKOptions options;
    options.loggingOptions.logLevel = Utils::Logging::LogLevel::Debug;

    //The AWS SDK for C++ must be initialized by calling Aws::InitAPI.
    InitAPI(options);
    {
        S3::S3Client client;

        auto outcome = client.ListBuckets();
        if (outcome.IsSuccess()) {
            std::cout << "Found " << outcome.GetResult().GetBuckets().size() << " buckets\n";
            for (auto&& b : outcome.GetResult().GetBuckets()) {
                std::cout << b.GetName() << std::endl;
            }
        }
        else {
            std::cout << "Failed with error: " << outcome.GetError() << std::endl;
        }
    }

    //Before the application terminates, the SDK must be shut down.
    ShutdownAPI(options);
    return 0;
}

Hi, thank you for the response! I did manage to solve the error by moving the libraries to a specific folder, then setting -DCMAKE_PREFIX_PATH=.
