Databricks App deployment fails: mysqlclient build error (pkg-config not found)

[vamsi_simbus]

Hi Community Members,

I’m deploying a Python project as a Databricks App, but deployment fails during dependency installation with:

ERROR: Failed to build 'MySQL client' pkg-config: not found Exception: Can not find valid pkg-config name

The dependency is pulled indirectly via:

ibis-framework[MySQL]

From my understanding, Databricks Apps don’t allow OS-level dependencies, and MySQL client requires native MySQL/MariaDB libraries—so pip fails when trying to build it from source.

Questions:

1. Are there any supported workarounds for native dependencies in Databricks Apps?

   Thanks in advance for your help!
