AWS::InitAPI fails on windows

[atitusfwd]

I'm trying to learn to use the AWS C++ SDK, windows platform, building with CMAKE. I have simplified this down to the basic skeleton defined here: https://docs.aws.amazon.com/sdk-for-cpp/v1/developer-guide/basic-use.html

The program source:

`#include <aws/core/Aws.h>

int main()
{
Aws::SDKOptions options;
options.loggingOptions.logLevel = Aws::Utils::Logging::LogLevel::Trace;
Aws::InitAPI(options);
{
printf("Hello CMake.\n");
}
Aws::ShutdownAPI(options);
return 0;
}`

The result is the same even if the options configuration is commented out. When running the executable, there is no output written to std out or std error, The log file is created but is completely empty (zero bytes). The return code from the program is
-1073741819 as obtained from %errorlevel% variable. If the program is run repeatedly, it will (infrequently) produce the following error stack trace to the console:

Fatal error condition occurred in C:\Temp\build\aws-sdk-cpp\crt\aws-crt-cpp\crt\aws-c-io\source\event_loop.c:74: aws_thread_launch(&cleanup_thread, s_event_loop_destroy_async_thread_fn, el_group, &thread_options) == AWS_OP_SUCCESS

I would really appreciate any suggestions as to how to determine the cause. Compiler info:
14.29.30037/bin/Hostx64/x64/cl.exe

Aws::InitAPI calls Aws::Monitoring::InitMonitoring which, apparently, somehow calls empty std::function... You can use debugger to figure out why

[KaibaLopez]

It seems to me like you got a linking issue, which can be due to a lot of things so...
Could you walk me through what steps you took to install the SDK and then how you're linking it to your application.

[atitusfwd]

My ultimate goal is to use the encryption sdk specifically. I followed the instructions that are in the readme of the git repo (these are the same steps that are in the aws docs). This repo: https://github.com/aws/aws-encryption-sdk-c/ . I had to make one change: when cloning the repo I had to add the recurse subprojects otherwise it was missing things and the cmake didn't work. I took the defaults and built 64 bit release libraries.

I created a new directory, grabbed the example string.cpp that is included with the encryption sdk, and using cmake with find exports to build it. When it didn't work (stuck in AWS:InitAPI, I made the simpler version to just isolate that and I get the same behavior. Here is the cmakelists that is building both:

cmake_minimum_required (VERSION 3.8)

project ("awsencrypt1")

find_package(aws-encryption-sdk-cpp)
link_directories(/apps/aws-encryption-sdk/lib)

add_compile_definitions(USE_IMPORT_EXPORT)

add_executable (awsencrypt1 "string.cpp")
target_link_libraries(awsencrypt1 PRIVATE AWS::aws-c-common aws-cpp-sdk-kms aws-cpp-sdk-core aws-encryption-sdk aws-encryption-sdk-cpp)
set_target_properties(awsencrypt1 PROPERTIES CXX_STANDARD 11 C_STANDARD 99)

add_executable (awstest1 "awsencrypt1.cpp")
target_link_libraries(awstest1 PRIVATE aws-cpp-sdk-core)
set_target_properties(awstest1 PROPERTIES CXX_STANDARD 11 C_STANDARD 99)

[atitusfwd]

For arguments to cmake, I'm specifying the following:
-DCMAKE_PREFIX_PATH="C:\apps\aws-encryption-sdk" -DBUILD_SHARED_LIBS=ON

The prefix path has the bin, lib and include folders with the header files, cmake packages, etc. It wants the BUILD_SHARED_LIBS property otherwise the cmake exports won't find everything.

[KaibaLopez]

Ok.. so the building seems fine to me, now I'm curious if it's a weird linking interaction between this sdk and the encryption-sdk (maybe some overwriting happening idk).
I'm not really familiar with the encryption-sdk so I'm not sure what the find_package includes for them....
So on that note could you try changing your CMakeLists to just use the cpp sdk?:

cmake_minimum_required (VERSION 3.8)

project ("awsencrypt1" LANGUAGE CXX)

find_package(AWSSDK REQUIRED COMPONENTS kms)
add_executable (awsencrypt1 "string.cpp")
target_link_libraries(${PROJECT_NAME} ${AWSSDK_LINK_LIBRARIES})
target_compile_options(${PROJECT_NAME} PRIVATE "-Wall")

Also, version 1.9 might have broken their sample, so you might also want to try using version 1.8 of this sdk when cloning, see if that works for you?

[atitusfwd]

I tried to build this with the cmakelists you specified. Cmake went OK

But the build failed; it could not find the header:

[atitusfwd]

I know I can manually specify the header location, but its supposed to get that automatically from the package, correct?

[KaibaLopez]

Ok I think I know what is going on, couple of things I'd like you to try:

1. Try adding -DCMAKE_INSTALL_PREFIX="C:\apps\aws-encryption-sdk" to your cmake argument. This should work but if it didn't, tell me the error.

2. Could you try using the default locations? Just remove -DCMAKE_PREFIX_PATH="C:\apps\aws-encryption-sdk" and -DCMAKE_INSTALL_PREFIX="C:\apps\aws-encryption-sdk". This should install in C:\Program Files (x86)\aws-cpp-sdk-all and cmake should be able to link with not extra instructions... I just want to make sure that there isn't something weird about your environment.

[atitusfwd]

I tried doing item number 1 first, The cmake worked, same as before. The build still failed. Same error.
