Re: [sage-support] Re: Error installing package scipy-1.12.0 in Develop

Curiously, this might be a regression in meson 1.3.2 (or perhaps your OS mangles it somehow), as Sage carries 1.3.1. Anyhow, the current meson version is 1.5.1, so both of these are old. On Sun, Sep 15, 2024 at 2:17 PM Kevin Youren wrote: > > Dima, > > well done and thank you! > > I started the

Re: [sage-support] Re: Error installing package scipy-1.12.0 in Develop

That's unfortunate, and it might be a bug in the meson/meson-python/ninja versions installed on your machine. (that's a curse of LTS versions, they often remain with old buggy versions). You can check if using instead versions vendored by Sage would work. Run ./configure --with-system-meson=no --

Re: [sage-support] Re: Error installing package scipy-1.12.0 in Develop

scipy itself is not built with configure/make, it's built with meson, which invokes ninja (a faster replacement for make, in particular it parallelizes the tasks much better - but in your case it goes overboard with it). You can see it in your log: [spkg-install] Found ninja-1.11.1 at /usr/bin/nin

[sage-support] f.g. subrings of polynomial rings and their Hilbert-Poincare series

We're looking for the ways to deal in Sage with finitely generated subrings S= of the ring of polynomials R[x_1,...,x_n] (R a field) of multivariate polynomial rings and their Hilbert-Poincare series. Once you have a presentation for S, i.e. S isomorphic to R[y_1,...,y_k]/I, with I an ideal in app
