Build

This instruction assumes the knowledge of building an IGOR XOP project. Chapter 3 of XOP Toolkit manual is a good reference.

  1. Requirements:
    • EPICS 3.14. It should be built statically and thus only one "EPICS.xop" file is needed to distribute.
    • IGOR XOP Toolkit. It is not free and costs $100.
    • Microsoft Visual Studio 2015 on Windows.
    • Xcode on macOS.

  2. Get source from Git repository, e.g. with a command line client,
    git clone git://git.code.sf.net/p/igor2epics/git igor2epics
    Or simply download a snapshot.

  3. Put XOPSupport folder from IGOR XOP Toolkit side by side igor2epics source folder.

  4. On macOS using Xcode. Open Xcode/EPICS.xcodeproj. In the "EPICS" project info dialog Build tab, change Header Search Paths and Library Search Paths to reflect your EPICS base setup, e.g. /Developer/epics/base-3.14.12, In order to link to the static libraries thus portable, remove *.dylib under /Developer/epics/base-3.14.12/lib/darwin-x86. Now select the architecture to build from menu Product->Scheme, EPICS for 32bit and EPICS64 for 64bit. Now build the product, and EPICS.xop or EPICS64.xop should be created under Products in the Project navigator.
  5. on Windows using Microsoft Visual Studio 2015, Open solution VC2015/EPICS.sln. In the "EPICS" project properties pages, change the Additional Include Directories and Additional Library Directories to reflect your EPICS base setup. By default the EPICS base is C:\epics\base-3.14.12*. Now build solution, and EPICS.xop or EPICS64.xop" (based on the active solution platform) should be created under VC2015.
