In order to compile StaRVOOrS you must have installed a Haskell compiler: ghc-7.8.3 or later recommended.
At the time of compiling, you can let cabal doing it for you as follows:
cabal configure
cabal build
Note that you will probably have to install the following packages:
language-java >= 0.2.7
haxml >= 1.25.3
split >= 0.2.2
lens >= 4.15.3
Then, for more recent compilers, use the standard Cabal method of installation:
cabal update
cabal install haxml
or runhaskell Setup.hs configure [--prefix=...] [--buildwith=...] runhaskell Setup.hs build runhaskell Setup.hs install
For older compilers, use:
./configure [--prefix=...] [--buildwith=...]
make
make install
In addition, to use the compiled code you have to download the APIs for KeY and LARVA:
