Installation

Get Herschel tarballs (released on Nov 19th, 2014)

$ curl -kLO https://raw.githubusercontent.com/gridaphobe/CRL/ET_2014_11/GetComponents  

$ chmod a+x GetComponents  

$ ./GetComponents --parallel https://bitbucket.org/einsteintoolkit/manifest/raw/ET_2014_11/einsteintoolkit.th  

May need to wait about 5 minutes (depend on the network speed)
After this, you should have a directory called "Cactus" contains tons of files.

Compile

Configuration files can be found at Cactus/simfactory/mdb/optionlists/*.cfg
The thornlist determine what to compile, can be found at Cactus/thornlists/*.th.
Default will on ly have einsteintoolkit.th
Find the proper config file and thornlist then copy them to the Cactus/

$ cd Cactus  
$ make <NAME>-config THORNLIST=BSSN_Hydro.th options=c3.cfg  
## Then config. You need say "yes" if asked.  
$ make <NAME>  

<NAME> is the name of the setting user-defined variable.
You can have different settings with different names.
Here I use tscc.

Debug

1. Add #include <math.h> into arrangements/EinsteinAnalysis/AHFinderDirect/src/jtutil/cpm_map.cc
