I've posted a topic with subject line starting from FAQ here few days
ago. It lists packages for Debian.
Not sure how different it is for Mint - one needs to try.

Re: [sage-devel] Re: Error while building

[Ibrahim M. Akrab]

I installed it and I think it no longer shows this error. However, it's
like we're playing cat and mouse since it keeps asking for packages and I
keep searching for and installing them.

First, it was gfortran then r and now pynac. I think a list of required
packages would be great to install before building.

Thanks for your help and time.

 Error building Sage.

 The following package(s) may have failed to build (not necessarily
 during this run of 'make all-start'):

 * package: gfortran-9.2.0
   last build time: Mar 9 00:27
   log file:/PATH/sage/logs/pkgs/gfortran-9.2.0.log
   build directory: /PATH/sage/local/var/tmp/sage/build/gfortran-9.2.0

 It is safe to delete any log files and build directories, but they
 contain information that is helpful for debugging build problems.
 WARNING: If you now run 'make' again, the build directory of the
 same version of the package will, by default, be deleted. Set the
 environment variable SAGE_KEEP_BUILT_SPKGS=yes to prevent this.

Hi,

we should do something with those file, since there are very good ideas
in there.

How large is the whole nt.sagenb.org + sagenb.org data ?

Ciao,

sage-build-env-config is strictly for building sage. User packages should

[sage-devel] nt.sagenb.org and sagenb.org

[William Stein]

Hi,

Somebody asked me about a link to a public notebook on the long-gone server
"nt.sagenb.org" at

https://mathoverflow.net/questions/54255/upper-bounds-for-ranks-of-modular-jacobians


so I tracked down the files for nt.sagenb.org.  If anybody is interested in
converting the 175 published files
from nt.sagenb.org to sage worksheets (or Jupyter notebooks) and publishing
them somewhere
(e.g., on share.cocalc.com and github.com), let me know and I'll give you
access.

I also still own the domain name sagenb.org, so if somebody wanted to put
in some effort they could even
make all the old sagenb.org links do something sensible.

Anyway, volunteer(s) welcome, since I don't have the bandwidth to do this
all myself, but I do know where
all the data is...

Re: [sage-devel] Confused about ARB_LIBRARY

[Dima Pasechnik]

This appears to be a result of https://trac.sagemath.org/ticket/29052
Indeed, the rationale, wrong or not, is that the env. var. SAGE_ARB_LIBRARY
is only needed for building, not for running, Sage, and setting of
this variable has been therefore moved into
build/bin/sage-build-env-config(.in).

If you source build/bin/sage-build-env-config, i.e.

$ . build/bin/sage-build-env-config

then on Debian

$ ./sage -c "print(sage.env.cython_aliases()['ARB_LIBRARY'])"
flint-arb

as it should be.

Not sure whether anything should be fixed here.

Best
Dima

A workaround is to install the system gfortran package.

The "success" branch of the AC_CHECK_LIB([flint-arb],... call in arb's
spkg-configure.m4 looks off to me, because AC_CHECK_LIB (unlike
AC_SEARCH_LIBS) doesn't prepend -l to LIBS if you provide a
non-empty success branch.

But, that doesn't explain why you're getting ARB_LIBRARY=arb. I would
expect that to be ARB_LIBRARY=flint-arb in any case. You might be able
to get more info by running ./configure again and looking for the arb
stuff in config.log.

Ok, I see how to call it, I needed to define some .

But I am not getting errors, maybe my vim is too old (7.4.1689). I need to 
update my machine but I am always postponing this to tomorrow.

It only works linewise, and is mapped to Y, which is 
probably something like \Y depending on your setup. You can use it 
either by selecting some text in visual mode and typing \Y, or typing \Y 
followed by a motion (e.g. \Yap). It will keep the input lines only and 
strip the sage: and : markers.

[sage-devel] Re: yanking sage doctests in vim

[Sébastien Labbé]

Thanks Marc!

Should I understand that it filters out the output? Can you tell how you 
use it?

In vim, I am able to use "+y to yank some block of sage doctest to the 
register + (i.e., the paste bin). I tried "+Y with your code, but it does 
not seem to work.

Since 2 years with some update of the ipython, I am not able to copy paste 
in tmux a multiline block from one pane to the pane containing the sage 
command line: it only copies the first line. A workaround is to type 
%cpaste first in sage which is painful. If you have a fix for that, I am 
interested.

[sage-devel] Confused about ARB_LIBRARY

[Marc Mezzarobba]

Is it expected that ARB_LIBRARY is set to 'arb' (as opposed to
'flint-arb') on a Debian box where Sage links against the system
arb?

The linker complains about not finding -larb when I try to build
an external cython module that uses sage.rings.complex_arb. And
indeed, it should have looked for -lflint-arb:

~/co/sage:develop$ ldd /home/marc/co/sage/local/lib/python3.7/site-
packages/sage/rings/complex_arb.cpython-37m-x86_64-linux-gnu.so | grep arb
libflint-arb.so.2 => /lib/x86_64-linux-gnu/libflint-arb.so.2 
(0x7fbf0c11b000)

My setup.py calls cythonize(..., aliases=sage.env.cython_aliases().
I thought this should be enough to make it resolve the references to
ARB_LIBRARY in acb.pxd to the correct library. However,
cython_aliases() doesn't return what I'd expect:

~/co/sage:develop$ sage --nodotsage
┌┐
│ SageMath version 9.1.beta7, Release Date: 2020-03-08   │
│ Using Python 3.7.3. Type "help()" for help.│
└┘
┏┓
┃ Warning: this is a prerelease version, and it may be unstable. ┃
┗┛
sage: sage.env.cython_aliases()['ARB_LIBRARY']
'arb'

This is with yesterday's beta. I don't remember seeing this issue
before, but I may not have rebuilt this module with every release.

Am I doing something wrong, or is this a bug?

Thanks a lot,
