Package: geogebra Version: 3.2.46.0+dfsg1-1 Severity: important --- Please enter the report below this line. ---
Hello,
recently i recognized, that geogebra does not seem to be able to calculate e.g.
the derivative of f(x)=x^2. I launched the program form the console and got
this:
$ geogebra

java.lang.Exception: Error during system script initialization.
MathPiper creation failed with scriptbase:
jar:file:/usr/share/geogebra/geogebra_cas.jar!/
MathPiper creation failed again with null scriptbase
typing x^2 followed by f'(x) yields to the following lines on the console
*** BEGIN Message from [geogebra.cas.GeoGebraCAS.evaluateMathPiper] at 8:30:58
free memory: 22368KB
String for MathPiper: D(x) (x)^(2)
Exception from MathPiper: Error encountered during initialization or parsing:
Error parsing expression, near token (.
*** END Message from [geogebra.cas.GeoGebraCAS.evaluateMathPiper] at 8:30:58

but on the oter hand integrating x^2 does work. does this look like a geogebra
bug or more like a mathpiper bug?
Thank you for your effort
Lorenz
