holy mother you did it @Mario Carneiro

Kenny Lau (May 23 2018 at 07:25):

congratulations

Mario Carneiro (May 23 2018 at 07:25):

You can see it's just a corollary of a much stronger theorem

Kenny Lau (May 23 2018 at 07:26):

oh and which commit should i checkout?

Kenny Lau (May 23 2018 at 07:26):

you didn't bother to build any

Mario Carneiro (May 23 2018 at 07:26):

I think Rice's theorem is cool

Mario Carneiro (May 23 2018 at 07:26):

?

Kenny Lau (May 23 2018 at 07:26):

I eat them every day

there are no green ticks after April 29

Mario Carneiro (May 23 2018 at 07:26):

that's weird

Mario Carneiro (May 23 2018 at 07:27):

travis usually kicks in automatically

Kenny Lau (May 23 2018 at 07:27):

so which commit should i use?

Mario Carneiro (May 23 2018 at 07:27):

I have been building locally so they should work, but I guess I should find out what's up with travis

Kenny Lau (May 23 2018 at 07:28):

and which lean version?

Mario Carneiro (May 23 2018 at 07:28):

3.4.1

Gabriel Ebner (May 23 2018 at 07:28):

Travis is broken on the other packages as well. "This is not an active repository
You don't have sufficient rights to enable this repo on Travis.
Please contact the admin to enable it or to receive admin rights yourself." @Sebastian Ullrich ?

Mario Carneiro (May 23 2018 at 07:28):

I always get that message, but it did not affect the build itself

Gabriel Ebner (May 23 2018 at 07:29):

Either way, super does not get built by travis either at the moment.

Sebastian Ullrich (May 23 2018 at 08:05):

I'll have to ask Leo

Kevin Buzzard (May 23 2018 at 08:06):

you have a halting problem

Sebastian Ullrich (May 23 2018 at 14:48):

https://travis-ci.org/leanprover/mathlib now looks more promising
