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 |

sagemathgh-38770: Add "needs" tags for giac and libgiac Part of sagemath#38668. If it's going to be possible to disable giac, we need to guard all of the tests that use it with either `# needs giac` or `# needs sage.libs.giac`. I think I've gotten them all. A crude way to test: 1. `git rm -r src/sage/libs/giac` and rebuild to disable sage.libs.giac 2. build sage, and then delete the giac executable to disable the pexpect interface If you do these one at a time, it should ensure that the correct tags are used. (Typically, if giac is missing, neither sage.libs.giac nor the giac executable will be present, making it very easy to mix up the tags.) For bonus points you can undelete `src/sage/libs/giac` after building but before testing to make sure the "needs" tags in those files are accurate. ### Dependencies: * sagemath#38756 * sagemath#38686 (not strictly required, but it adds a few "needs sage.libs.giac" tags of its own) URL: sagemath#38770 Reported by: Michael Orlitzky Reviewer(s): Tobias Diez
