This change has been marked as submitted.


Review request for KDE Edu and Aleix Pol Gonzalez.


Repository: analitza


Description
-------

Insert a cast in free() call on OSX in order to avoid this:
```
Building CXX object analitzaplot/CMakeFiles/AnalitzaPlot.dir/private/utils/marchingcubes.cpp.o
[ 65%] /Users/marko/WC/KDECI-builds/analitza/calgebra/main.cpp:157:3: error: no matching function for call to 'free'

Testing
-------

+ analitza builds fine w/o error

+ Wondering though, why HAVE_FREE_HISTORY_ENTRY is undefined...
 (Does readline get properly detected on OSX?)


Thanks,

Marko Käning
