The handful of failures on Linux and Mac seem to be due the changed print style in Arb 2.20, so just a matter of updating the doctests. Then for Windows you have a ton of these which probably all result from the same bug somewhere in python-flint (maybe a lingering |
It might actually be a problem in Arb. There are a lot of compiler warnings in the Windows build log from building Arb (before python-flint is built) like: |
|
I've updated the doctests and now the Linux/OSX tests are passing. |
|
Those compiler warnings are false positives in GCC 11 and later; see flintlib/flint#1079 Nevertheless, I suppose to debug this, a good start would be to run the Arb test suite after building Arb, to see if that catches anything? |
Are you sure they're the same? It's |
Yeah, those seems to be two sides of the same coin. Do the same warnings show up when building Flint? |
|
I've attached the part of the Windows build log that builds flint, arb and python-flint: build_log.txt There are some warnings from flint as well like: Building Arb gives many more warnings like that. Building python-flint itself gives one warning about signed/unsigned comparison which isn't seen in the logs I think because cibuildwheel hides it. I see the same warning when building locally on Linux though: $ bin/build_inplace.sh

The tests completed quickly enough on Linux and passed. They failed immediately on OSX because it couldn't find the shared library (hopefully fixed by last commit). They failed on Windows: Hopefully that's the same problem as OSX so need to wait for latest commit to see... |
Once this issue is resolved I'll leave the test run in but with a reduced multiplier for ongoing CI. |
There are a lot of places where python-flint uses long but flint uses slong. Should we basically change every use of long in python-flint? |
It would be nice if there was some way to have the types declared in cython actually checked by the C compiler... |
|
Still the same problem with running the tests on Windows. There isn't any meaningful error message so I'm not sure where to go from there. The Arb tests on Linux are passing and it looks like they will pass on OSX as well. |
Yes, this may be necessary. |
The very first test failing suggests that the test programs don't manage to link to the library or something like that. |

For now I will remove the |
Probably. That was the problem with OSX. I'd have to switch over to the Windows machine I've been using to try it locally. |

Okay, that will do for now. This has fixed the doctests and makes sure that they are tested in CI. It currently shows that they fail on Windows but that can be something to fix in another PR. The failing doctests all look like this and are all in The two |

Currently these doctests should fail. I'm going to push them to CI first just to see the output on all platforms and then I'll push another commit to fix the doctests.
