How to use AWS SDK purely statically

[HavenRemix]

Describe the issue

Basically I do not want to use .dll files, only the .lib files.

I am attempting to build the sdk statically by using the flags -DBUILD_SHARED_LIBS=OFF, -DFORCE_SHARED_CRT=OFF, and, if it is relevant, -DBUILD_ONLY="cognito-idp".

This however results in a lot of errors. After doing a fail amount of digging online, seems these errors occur when trying to build statically something meant to use built as a dll.

So, is it possible to use the library purely statically, or is using the .dll files necessary.

Steps to Reproduce

Build the sdk with the flags -DBUILD_SHARED_LIBS=OFF, -DFORCE_SHARED_CRT=OFF, and, if it is relevant, -DBUILD_ONLY="cognito-idp".

Current behavior

The project is built using the following command:

cmake "C:\AWS\aws-sdk-cpp" -G "Visual Studio 17" -A x64 -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH="C:/AWS/Install" -DBUILD_SHARED_LIBS=OFF -DFORCE_SHARED_CRT=OFF -DBUILD_ONLY="cognito-idp"

This is successful.

Then I execute the following command:

"C:\Program Files\Microsoft Visual Studio\2022\Professional\Msbuild\Current\Bin\MSBuild.exe" ALL_BUILD.vcxproj /p:Configuration=Release

I receive the following errors and warnings:

Update: I tried building it with a different mix of flags, and it finally built successfully.

It seems, though, that it can only be used with dlls, as now when using it in an actuall project I am received unresolved external errors referencing dllimports.

Am I correct in assuming the sdk can only be used will dlls and there is no way to use it without?

Thanks,

Hi @HavenRemix you can use static build and it should only require static libs which are .lib files. I see that you have been setting the correct flags off (BUILD_SHARED_LIBS and FORCE_SHARED_CRT). When you mentioned on second comment: Update: I tried building it with a different mix of flags, and it finally built successfully. What cmake command line did you use?

[HavenRemix]

Hi,

I build it using the following command line:

cmake "C:\AWS\aws-sdk-cpp" -G "Visual Studio 17" -A x64 -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH="C:/AWS/Install" -DBUILD_SHARED_LIBS=OFF -DFORCE_SHARED_CRT=ON -DBUILD_ONLY="cognito-idp"

This builds successfully, however, it does not compile when used in the project.
