epics-ca

Rust bindings for EPICS Channel Access protocol.

Requrements

This crate requires built epics-base or at least ca library.

During build you need to provide a path to a static library (libca.a or ca.lib). This could be done either by:

  • setting EPICS_BASE env variable that contains path to epics-base root, or
  • adding to RUSTFLAGS a path where static library file is stored (e.g. -L /opt/epics-base/lib/linux-x86_64).

At run time the crate also needs a dynamic library (libca.so or ca.dll). You need to provide path to its location (e.g. via LD_LIBRARY_PATH) or put it where it could be found automatically (e.g. along with executable).

Testing

To run tests you need to have dummy IOC running (located in ioc dir):

  • Set appropriate EPICS_BASE path in configure/RELEASE.
  • Build with make.
  • Go to iocBoot/iocTest/ and run script st.cmd and don't stop it.

In separate shell run cargo test.
