It just ocurred to me: why does all this work with sage 8.1? Is it only the cython upgrade? Martin -- You received this message because you are subscribed to the Google Groups "sage-devel" group. To unsubscribe from this group and stop receiving emails from it, send an email to

Would a setup.py be an alternative to pyximport? If so, how would I go about it (making the example at hand work would probably be sufficient.) Thanks in any case! Martin > > -- You received this message because you are subscribed to the Google Groups "sage-devel" group. To unsubscribe

In my experience, it can help to run Xcode once after upgrading so that it can install some "additional components". Did you re-install command line tools by upgrading through the app store, or some other way? On Tuesday, April 24, 2018 at 8:57:30 AM UTC-7, Christelle Vincent wrote: > > Hi, >

Hi, I am trying to build Sage 8.1 from source on Mac (High Sierra 10.13.4, just updated Xcode and re-installed Command Line Tools). I get the error "Error building package python3-3.6.1.p1" I am attaching the whole log but it ends with Undefined symbols for architecture x86_64:

It might be an issue with the "printing" order which is used to sort stuff in pynac internally (but not in orignal ginac) and we already had issues with in the past. -- You received this message because you are subscribed to the Google Groups "sage-devel" group. To unsubscribe from this group

Ok I finally ended up in pynac code. It seems there is a bad recursion happening, with the following reversed backtrace: (Sage.)Expression._mul_ Ginac::* Ginac::exmul Ginac::ex::ex Ginac::ex::construct_from_basic Ginac::mul::eval Ginac::ex::ex Ginac::ex::construct_from_basic Ginac::mul::eval ...

Kind of strange, running sage -gdb I never end up in Expression._mul_ but at random places in Python code. On Tuesday, April 24, 2018 at 2:40:50 PM UTC+2, Frédéric Chapoton wrote: > > Amusing.. Also hangs on > > sage: (1/e1)/e2 > 1/2*sqrt(2)/((I - 1)*sqrt(2) - 2) > sage: 1/_ > > > Le mardi 24

[sage-devel] Product of two expressions that causes hang

Hi all, In working on an unrelated topic I encountered an indefinite hang, which I narrowed down to the following exact operation (I haven't found a way to simplify it further): sage: e1 = sqrt(2)*I - sqrt(2) - 2 sage: e2 = sqrt(2) simple enough, right? But then it appears to hang forever in
