    RvtkStatismo: Now working on OSX

    22 Dec 2015

    As I got hands on a VM running OSX Yosemite, I managed to install RvtkStatismo on OSX. Unfortunately in Yosemite, the hombrew packages seem not work correctly, so let us do the statismo superbuild.

    Install R and XCODE, run the following lines in your terminal:

     git clone https://github.com/statismo/statismo.git
 mkdir build && cd build
 cmake ../statismo/superbuild 
 make ## make a coffee or go for lunch

    There are two ways to tell R, where the libraries reside:

    1. Dirty solution. Copy the libs to where R can find them:
    	
cp INSTALL/lib/libvtk* INSTALL/lib/libboost* INSTALL/lib/libhdf5* /Library/Frameworks/R.framework/Resources/lib
    1. In OS X Yosemite there seems no way to set the environment variable DYLD_LIBRARY_PATH globally, so we create a file ~/Library/LaunchAgents/statismo.plist containing the following (of course replacing the path with yours):
        <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
    <plist version="1.0">
    <dict>
      <key>Label</key>
      <string>my.startup</string>
      <key>ProgramArguments</key>
      <array>
        <string>sh</string>
        <string>-c</string>
        <string>
        launchctl setenv DYLD_LIBRARY_PATH /Users/myuser/statismo/build/INSTALL/lib
       </string>
    
      </array>
      <key>RunAtLoad</key>
      <true/>
    </dict>
    </plist>

    Now logout and login again. To use RvtkStatismo in a console you need to run (works for one session only):

        export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:/Users/myuser/statismo/build/INSTALL/lib
	```


Fire up R and run 

```r
install.packages("devtools")
devtools::install_github("zarquon42b/RvtkStatismo",args="--configure-args='path_to_superbuild/Statismo-build'")

    Happy holidays.
