Install CACTUS on SLC5 (Scientific Linux CERN)

CACTUS installation on SLC5 is supported by RPM/YUM

1. Download the CACTUS repo file
   • cactus.repo (SLC5 64-bit) file
   • cactus.repo (SLC5 32-bit) file
2. Copy the repo file to /etc/yum.repos.d

      $ sudo cp cactus.repo /etc/yum.repos.d
      

3. Install the software using YUM

      $ sudo yum groupinstall cactus
      

4. When installation is complete, then the CACTUS software package should be in /opt/cactus

Install CACTUS on SL5 (Scientific Linux)

CACTUS installation on SL5 is not supported by RPM/YUM and must be done manually.

1. Install the prerequisites for the installation using YUM

      $ sudo yum -y install bzip2-devel zlib-devel ncurses-devel python-devel readline-devel
      

2. Check out the code from SVN into the desired location your machine.

      $ svn co https://svn.cern.ch/reps/cactus/trunk
      

3. Be sure the CACTUS root directory trunk/ is where you want it. In the following steps, I will just assume the code has been checked out into the user's home directory.
4. Go the 'trunk' directory of the CACTUS code and build the package

      $ cd ~/trunk/
      $ make
      

5. The build may take a long time--on the order of an hour--so be patient. If any errors occur, make sure that all of the above-mentioned prerequisites are indeed installed and up-to-date, and try again.

Install PyChips

NOTE that PyChips is not supported by IPbus v2, and therefore will not work with the AMC13XG or greater than AMC13 rev1 T1/T2 firmware version 0x25/0x13. PyChips installation is not supported by RPM/YUM and must be done manually

1. Download the PyChips tar file from SVN to the desired directory on your machine (i.e. ${HOME}/PyChips_1_4_3)

      $ svn co http://cactus.hepforge.org/svn/branches/PyChips_1_4_3 ~/PyChips_1_4_3
      

2. Set your environment

      $ export PYTHONPATH=$HOME/PyChips_1_4_3/src:$PYTHONPATH
      

3. PyChips is successfully installed! In order to use it in a python script, be sure to include the statement from PyChipsUser import * at the head of your file
