Amazon Linux:2 Docker- After install While using the sdk - Could NOT find crypto (missing: crypto_LIBRARY)

[mandeepsingh-private]

Describe the bug

While using the aws sdk in my code using Cmake, I get Could NOT find crypto (missing: crypto_LIBRARY) error since last 8 days, suddenly in Docker.

I dont get this error while building my code on Mac Os or Ubuntu Linux but see this error in Docker using Amazon Linux 2

Expected Behavior

Hello,
Could you please make sure that you have development packages for OpenSSL installed on your image/system?
Amazon Linux 2 is a yum-based distro and it has a dedicated package for OpenSSL crypto static lib called openssl-static (not included into devel package), i.e.:

sudo yum install openssl-devel
sudo yum install openssl-static

Best regards,
Sergey

[mandeepsingh-private]

Thanks for response

I did have this statement in the Docker
RUN yum install libcurl-devel openssl-devel libuuid-devel pulseaudio-libs-devel -y

as specified on instructions here
https://docs.aws.amazon.com/sdk-for-cpp/v1/developer-guide/setup-linux.html

but don't have "openssl-static"
I am wondering why would it suddenly give error ? It was working for past 4 months.

[SergeyRyabinin]

I am wondering why would it suddenly give error ?

We have updated our CRT dependency which brings quite some changes to our dependency tree.

Thanks for bringing up the documentation page, we will follow up with updating it.

[mandeepsingh-private]

Also noticed that docker file listed here in your repo is also not updated

(https://github.com/aws/aws-sdk-cpp/blob/master/CI/docker-file/AmazonLinux2/Dockerfile)

After the update
sudo yum install openssl-static

it worked thank you

I've got a project that builds the AWS SDK on Alpine 3.16.2 that started having an issue finding libcrypto while building the SDK precisely beginning with AWS SDK 1.9.235, which is right after fdf5a3c added cmake/Findcrypto.cmake to the AWS SDK project.

Then beginning with AWS SDK 1.9.255, it became exactly this issue, where the SDK is built but then when used by a project it couldn't find libcrypto as above.

That's right after e5cda3f (which also amends the erroneous commit 62c00f7 right before it).

Interestingly, the Alpine system where this is occurring, libcrypto.so remains exactly where it has always been:

$ ls -l /usr/lib/libcrypto.so*
lrwxrwxrwx    1 root     root            16 Aug 18 12:16 /usr/lib/libcrypto.so -> libcrypto.so.1.1
lrwxrwxrwx    1 root     root            26 Aug  9 08:47 /usr/lib/libcrypto.so.1.1 -> ../../lib/libcrypto.so.1.1

$ ls -l /lib/libcrypto.so*
-rwxr-xr-x    1 root     root       2609840 Jul  5 15:06 /lib/libcrypto.so.1.1

So, it looks like it is failing because it cannot find the static libraries if they are not installed. This is even though I'm building the SDK with -DBUILD_SHARED_LIBS=OFF.

Following the advice above, I did:

$ apk add openssl-libs-static 

This brings in:

$ apk info -L openssl-libs-static
openssl-libs-static-1.1.1q-r0 contains:
usr/lib/libcrypto.a
usr/lib/libssl.a

Now it works. The SDK builds, and the project builds.

So, it works because the static library is installed, even though the project I'm building ends up linking with the libcrypto.so shared object anyway.

So, perhaps it's a bug that the static library files must be installed even when only the shared library will be used.

In anyone is interested, this is the dockerfile that I'm using to build the build environment which works with the latest AWS SDK:

It is used to build lambda functions that interact with S3 and do some processing on image files stored there.

Hi Ildar,

Thanks a lot for deep investigation of the linking issue.
I'm sorry that you experience such complicated build process. We are working on improving our build system, it is tracked by this issue: Improvement to build, install, and distribution mechanisms #1888.

openssl-libs-static seems unnecessary, but currently the AWS SDK won't let the project build unless the static objects are installed

Unfortunately, static libcrypto is required by one of our dependencies: AWS CPP SDK dependency tree is complicated, we use AWS CRT libraries which includes s2n and (optionally) aws-lc libraries.
In particular, s2n library had (has in our case) the same static required dependency on libcrypto, changed in the following PR: Don't force static crypto dependency in case of a static build #3395.
At the same time, our CMakeLists always builds CRT in static mode, if OpenSSL libcrypto is selected, which triggers s2n to require a static libcrypto (what is changed by PR 3395 (same link as above), but not yet integrated in our SDK).
We will update our CRT dependency soon as mitigation and improve our overall build script in #1888.

Thanks again for your dive deep into the linking issue.

Best regards,
Sergey

I'm quite excited about #1888. I'll be watching the progress on that issue.

Starting with AWS SDK 1.9.255, I'm able to build the SDK without openssl-libs-static. I have also discovered that I can then get the downstream project to build using that build of the SDK by setting:

-Dcrypto_LIBRARY=/usr/lib/libcrypto.so

Or:

set(crypto_LIBRARY "/usr/lib/libcrypto.so") 

[specious]

I have an idea of how to maybe approach this nuanced situation.

Here's what I did:

diff --git a/cmake/Findcrypto.cmake b/cmake/Findcrypto.cmake
index 5425280d74..8b2014a718 100644
--- a/cmake/Findcrypto.cmake

         if (BUILD_SHARED_LIBS)
             set(crypto_LIBRARY ${crypto_SHARED_LIBRARY})
         else()

This carries the benefit that crypto_LIBRARY can be outright provided, but if the file is not found then the fallback will be to look for it.

However, the build crashes not while executing cmake/Findcrypto.cmake which is installed under lib/cmake/AWSSDK/Findcrypto.cmake, but lib/s2n/cmake/modules/Findcrypto.cmake:

./lib/cmake/AWSSDK/Findcrypto.cmake

./lib/aws-c-cal/cmake/modules/Findcrypto.cmake

The other two aren't in this repository. They come from here and here during the AWS SDK installation process.

These three files look like slightly different versions of essentially the same thing.

So, I amended the first one in the source code and patched the other two post-install like this:
