Basic Information

labCA is an EPICS Channel-Access Interface for SCILAB and MATLAB

Further information, documentation and build/install instructions can be found here

Quick instructions:

RUN INSTRUCTIONS

• point your PATH to bin/
• point your LD_LIBRARY_PATH to lib/<arch> (linux/solaris only)
• the environment variable PATH (win32) / LD_LIBRARY_PATH (linux, solaris) may also have to point to your EPICS base bin/<arch> (win32) or lib/<arch> (linux, solaris)

MATLAB:

• start matlab;
• addpath bin/<arch>/labca
• ready to go, type e.g. help labca

if MATLAB 2020b hangs, this is most likely due to MATLAB problems. Try setting LD_PRELOAD environment variable (prior to launching MATLAB): setenv LD_PRELOAD <path_to_epics_base>/lib/<arch>/libCom.so

SCILAB:

• start scilab
• exec bin/<arch>/labca.sce
• ready to go, type e.g. help lca

BUILD FROM SOURCE

• edit configure/CONFIG and set target application (MAKEFOR=MATLAB or MAKEFOR=SCILAB) and (optionally) the installation directory. You can also enable (experimental) support for Ctrl-C handling there. With this feature enabled, you can interrupt lcaGet/lcaPut by hitting Ctrl-C on the keyboard.

• edit configure/RELEASE to point to your installation directories of

  • EPICS base
  • MATLAB
  • SCILAB

  and (WIN32 only)

  • set MATLIB_SUBDIR to point to your compiler dependent libmx/libmex versions.

• set EPICS_HOST_ARCH environment variable.

• run GNU make from this directory.

• In order to build documentation you need more tools (pdflatex, latex2html and lynx). Building the documentation is skipped if any of these tools is missing.
