could you please provide reproduction steps, if we can reproduce we can fix it. If i had to take a guess though wherever your application is linking from is linking a old version of aws-crt-cpp

Hi,

I am using https://github.com/aws/aws-iot-device-sdk-cpp-v2 as well. But it was not updated to latest. After updating the version to v1.32.6, most of the linking errors are resolved.

But now I am seeing

/usr/bin/ld: /ros_ws/src/install/tools/lib/libaws-cpp-sdk-core.so: undefined reference to Aws::Crt::Crypto::SymmetricCipher::GetState() const' /usr/bin/ld: /ros_ws/src/install/tools/lib/libaws-cpp-sdk-core.so: undefined reference toAws::Crt::ByteBufInit(aws_allocator*, unsigned long)'

This is because, in aws-iot-device-sdk-cpp-v2 aws-crt-cpp is not updated to latest one where GetState and ByteBufInit are added. So can you please check and do the needful.

[DmitriyMusatkin]

iot sdk bumped their crt dependency and that should resolve this issue. https://github.com/aws/aws-iot-device-sdk-cpp-v2/releases/tag/v1.32.7

[srinivasab3]

Now I am able to build my app successfully with v1.32.7.

But now I am getting following error while running the app..

Jun 06 12:58:28 localhost cis[16075]: s2n_init() failed: 402653268 (The libcrypto major version name seen at compile-time is different from the major version name seen at run-time) Jun 06 12:58:28 localhost cis[16075]: Fatal error condition occurred in /ros_ws/src/IhmJellyfishAwsSdkSource/aws-iot-device-sdk-cpp-v2/crt/aws-crt-cpp/crt/aws-c-io/source/s2n/s2n_tls_channel_handler.c:203: 0 && "s2n_init() failed"

[DmitriyMusatkin]

That error means that libcrypto present during runtime was different than the one used during compilation (ex. compiled against openssl 1.1.1, but running against 3.0). things like strace can tell you which lib is being loaded at run time
