For what it's worth, I did overlook a few indirect uses of
interval_products_wrapper(). It's called by hypellfrob::matrix(),
which I didn't realize was visible in hypellfrob.h. I've set the
ticket to needs_work temporarily for want of benchmarks.

Invoking "setup.py install" is always wrong, it should not be used directly 
anymore.

Try "pip install ." instead

Re: [sage-devel] Re: pip-21.1.2 compile fails on MacOS

[Dima Pasechnik]

anyhow, Conda for Sage Developers needs updates.
Before doing

cd src/
python setup.py install

one needs to do the same for a number of packages in
pkgs/

cd pkgs/sage-conf
python setup.py install
cd ../sage-setup
python setup.py install

and I also did

pip install memory-allocator

because some of these was failing with an error there


Perhaps Matthias can tell us more about the precise order and need.

hmm. First I just installed Sage 9.4 as a conda package, (getting sage
env), and then
tried your sage-build env. instructions.

Re: [sage-devel] Re: pip-21.1.2 compile fails on MacOS

[Isuru Fernando]

It's not good to have two conda environments. I'm not sure how you got them
both involved in the build.

`mamba install pari -n sage-build` will install sage in `sage-build` env.

Re: [sage-devel] Re: pip-21.1.2 compile fails on MacOS

[Dima Pasechnik]

Conda's pari packages are a bit broken (they are per env, but not
quite), and this test fails:

configure:21400: result: libpari's datadir does not match GP's datadir. Not good
configure:21449: no suitable system package found for SPKG pari

namely, GP's datadir is
/Users/dima/opt/miniconda3/envs/sage-build/share/pari
but libpari's datadir is
/Users/dima/opt/miniconda3/envs/sage/share/pari

and if I try "mamba install pari" I just get

All requested packages already installed.

I suppose I don't understand conda's environments well - how does one tell
conda to install pari (and libpari) into sage-build?

 Hi Harald,

 We don't have Sage ported to macos 12 yet, I am afraid.
 We have been fighting macos 11 until April, see
 https://trac.sagemath.org/ticket/30651

 I've just opened https://trac.sagemath.org/ticket/32855

 Binaries built on macOS 10 or 11 might run on 12, but building is
 another story.

 Can one install Sage on macOS 12 using (mini)Conda at all ?

 I think building might be easier with Homebrew rather than Conda, too.

 Cheers,
 Dima

No, it's binary only. See https://wiki.sagemath.org/Conda section "Conda
for sage developers" if you want to do that.
(Btw, that hasn't been updated in a while and might not work due to a
recent restructure of sage build system)

Re: [sage-devel] Re: pip-21.1.2 compile fails on MacOS

For this issue, you need setuptools 58 or higher.
Or remove the line
https://github.com/sagemath/sage/blob/f5efe4883f348e01ca3069ed82bf517a4de337f6/build/bin/sage-build-env#L174

Re: [sage-devel] Re: RFC: zn_poly removal

I think we'd be fine dropping zn_poly even if it is 2 or 3 times faster.

[sage-devel] Re: pip-21.1.2 compile fails on MacOS

[Dima Pasechnik]

Hi Harald,

We don't have Sage ported to macos 12 yet, I am afraid.
We have been fighting macos 11 until April, see
https://trac.sagemath.org/ticket/30651

I've just opened https://trac.sagemath.org/ticket/32855

Binaries built on macOS 10 or 11 might run on 12, but building is another 
story.

Can one install Sage on macOS 12 using (mini)Conda at all ?

I think building might be easier with Homebrew rather than Conda, too.

Cheers,
Dima

I run into the same issue without miniconda, and thus cannot build Sage at 
all.

Re: [sage-devel] Re: RFC: zn_poly removal

[Alex J Best]

Right, that seems like a fair benchmark to me, does zn_poly (falling back 
to ntl) run faster than the force ntl = 1 version in enough ranges of 
variables to justify its continued existence?
Knowing whether it failed and fell back (and hence was slower) or just is 
simply slower doesn't seem to matter compared to the end result, knowing 
where its slower.

Yes exactly, I forgot now why we decided to use force ntl=1 for cyclic 
covers, and indeed I forgot that we did force it completely, I really have 
no idea the reasons that went into that decision anymore unfortunately.
