Unable to load mod_aws_transcribe

[realsama]

Hello, thank you fro providing this libs. I have been able to install and use mod_google_transcribe successfully but I can't get mod_aws_transcribe to work properly. The below is my error.

2024-06-25 16:16:54.926542 73.60% [CRIT] switch_loadable_module.c:1750 Error Loading module /usr/local/freeswitch/mod/mod_aws_transcribe.so
**/usr/local/freeswitch/mod/mod_aws_transcribe.so: undefined symbol: aws_symmetric_cipher_destroy**

I have lifted the relevant parts in the provided configure.ac and Makefile.am files in your packer repository. I can't use the ansible/packer script because I have a custom build process. Can you help provide some pointers on how to solve this? Thank you.

Having the same issues with the deepgram and assemblyai modules.

freeswitch> load mod_assemblyai_transcribe
+OK Reloading XML
-ERR [module load file routine returned an error]

I'm building the module and then running on a separate system using the official 1.10.9 release for Ubuntu 22.04, libwebsockets-dev is installed on that system.

These modules are provided for use with jambonz (jambonz.org), unfortunately I no longer have time to troubleshoot other implementations.

I have been able to create a Cmake file that compiles the needed symbols properly.

You need to install the was cpp sdk before trying to compile.
