src/sage/symbolic/integration: make libgiac integration optional

Open orlitzky opened this issue 1 year ago • 3 comments

We turn the libgiac integrator into a no-op if libgiac isn't available. That way, in the default integration routines, it is essentially skipped. If it were tried last, we could literally skip it; but currently it lives between maxima and sympy and cannot be rearanged without messing up some doctests.

Shouldn't the test for giac presence go via src/sage/features/giac ?

It's not using the "giac" executable, only the libgiac interface. I guess we could use the sage.libs.giac feature, but since this code is already going to import sage.libs.giac, it was simpler to catch the ImportError.
