Building Pelegant

The steps in building Pelegant on Linux are as follows:

1. Install MPICH (1 or 2) [2]. Your cluster administrator will need to do this.
2. If you are using an x86 processor, set the environment variables HOST_ARCH and
   EPICS_HOST_ARCH to linux-x86. If you are using a ppc processor, you can set these variables to linux-ppc.
3. If EPICS/Base is already installed on your computer, you can skip to the next step. Pelegant is built using the EPICS/Base configure files available from the OAG web site at APS. You will need to unpack this to create epics/base/configure. Go to the epics/base directory and type ``make.''
4. Next you will need to download the EPICS extensions configure files from the OAG web site. This will unpack to create epics/extensions/configure. Go to the epics/extensions/configure directory and type ``make.''
5. Download the latest SDDS source code from the OAG web site. This will unpack to create epics/extensions/src/SDDS. Go to this directory and type ``make.''
6. Download the OAG configure files from the OAG web site. This will unpack to create oag/apps/configure. Go to this directory and type ``make.''
7. Download the Pelegant source code from the OAG web site. This will unpack to create oag/apps/src/elegant.
8. Set the path for your installation of MPICH in Makefile.OAG in oag/apps/src/elegant.
9. From oag/apps/src/elegant, run the following command to build Pelegant:

    make Pelegant
   

   Pelegant should now exist at oag/apps/bin/linux-x86/Pelegant. (To build the serial version, just type ``make.'' This will also build related software.)

   elegant and Pelegant share the same source code. Makefile will decide which part of code will be compiled according to the binary file (either Pelegant or elegant) you want to build.
