Dear Comer:

I would like to confirm you that Ian and Eric were able to correctly find out the problem that originated  the build
problem on build using macports
* The HDF5 MacPorts port was updated from 1.8.14 to 1.8.15 on 16-May-2015
 (https://trac.macports.org/log/trunk/dports/science/hdf5/Portfile), 2 days before the ET release
* HDF5 is undefining __attribute__, and this is creating site effect  (caused by including hdf5.h)
 that have standard c++ include to fail. This is true for gcc4.8 and gcc5.1
* A simple solution is to change the order of includes in the include  file:
 arrangements/Carpet/CarpetIOHDF5/src/CarpetIOHDF5.hh. you can replace this include with the
 one attached to the present mail.

* to have a fast start you may also copy the attached file: osx-macports.run in
  simfactory/mdb/runscript.
* then set your local machine with the command

simfactory/bin/sim setup

* edit the local machine file you created (using the previous command) in simfactory/mdb/machine
 to have:


*** ASSUMING MACPORT IS INSTALLED (subversion is needed cause the version that comes with XCOde
*** will not work [new XCODE 6.3.2 and MacPorts 2.3.3]


sudo port install subversion
sudo port install pkgconfig gcc49 fftw-3 gsl jpeg zlib hdf5 +fortran +gfortran openmpi openssl

###  [FROM a MAIN DIRECTORY for the Cactus tree]  

curl -kLO https://raw.githubusercontent.com/gridaphobe/CRL/ET_2015_05/GetComponents
chmod a+x GetComponents
./GetComponents --parallel https://bitbucket.org/einsteintoolkit/manifest/raw/ET_2015_05/einsteintoolkit.th

### [the enter in the cactus directory]

cd Cactus

cp [where_you_save_it]/CarpetIOHDF5.hh   arrangements/Carpet/CarpetIOHDF5/src/
cp [where_you_save_it]/osx-macports.run  simfactory/mdb/runscript
simfactory/bin/sim setup

### [DO the local editing. In my case was the file named]
### the following line should be present
###
###  optionlist      = osx-macports.cfg
###  runscript       = osx-macports.run
###  ppn             = 4
###  max-num-threads = 4
###  num-threads     = 1
###  nodes           = 1
###
### NOT: my machine is “iMac (27-inch, Late 2009)”
###   OS X Yosemite 10.10.3
###
###   Processor Name: Intel Core i5
###   Processor Speed: 2,66 GHz
###   Number of Processors: 1
###   Total Number of Cores: 4
###   L2 Cache (per Core): 256 KB
###   L3 Cache: 8 MB
###   Memory: 8 GB


simfactory/bin/sim build --thornlist thornlists/einsteintoolkit.th
simfactory/bin/sim create-run static_tov --parfile=par/static_tov.par --proc=4 --num-threads=2

### Now the test TOV simulations should be running code is running on two process using two cores each.


## sudo port install python27
## sudo port select —set python python27
## sudo port install py-numpy py-scipy
## sudo port install py-matplotlib
## sudo port install py-h5py
## sudo port install py-ipython
## sudo port select —set ipython ipython27
##
##
## TO SEE THE RESULTS:

ipython —-pylab
