epicscorelibs

Not an end user library.

This repository contains the source used to build

https://pypi.org/project/epicscorelibs/

pip install epicscorelibs

If you plan to use this for local compilation then it is will be necessary to skip the pre-built wheel binaries.

pip install --no-binary :all: epicscorelibs

Please report issues first to https://github.com/mdavidsaver/epicscorelibs/issues before code.launchpad.net or EPICS mailing lists.

Python API

See src/python/epicscorelibs.

Finding paths to included headers and libraries.

from epicscorelibs.path import include_path, lib_path, get_lib
print(include_path) # use with eg. -I
print(lib_path)     # use with eg. -L
print(get_lib('ca'))# full path of named library
# lib names are: 'Com', 'ca', 'dbCore', 'dbRecStd', 'pvData', 'pvAccess', 'pvAccessCA'

Using with pyepics and/or cothread.

It is advisable to avoid loading more than one version of any of the epics library into a single process. To facilitate this several helpers are provided for common libca wrappers.

DLS cothread

pip install epicscorelibs cothread

try:
    import epicscorelibs.path.cothread
except ImportError:
    pass
from cothread.catools import caget    

pyepics

try:
    import epicscorelibs.path.pyepics
except ImportError:
    pass
import epics
