Re: [sage-devel] Re: trouble upgrading to latest stable version

[Anne Schilling]

Thank you! I installed all those. Now it hangs here:

I tried to install freetype by hand, but it does not seem to help.

[sage-devel] conditional install of optional package

[Thierry]

Hi,

i am on the way to build a version of Sage Debian Live for 9.1. I would
like to benefit from the spkg-configure.m4 feature when installing
optional packages, as much as possible.

Say, i want to install cbc, looking at build/pkgs/cbc/distros/debian.txt
i install coinor-cbc coinor-libcbc-dev from the distro.

However, when i do 

sage -i cbc

it still installs cbc from Sage spkg, which i would like to avoid. What
is the command that installs cbc (say) only if the distro replacements
are not installed on the system ?

Ciao,
Thierry

Re: [sage-devel] Re: trouble upgrading to latest stable version

[Matthias Koeppe]

You could try if "brew install libpng" fixes this problem (otherwise you'd 
need to manually clean out /usr/local/lib/libpng*)

Also, note that at the end of the configure output, some commands were 
recommended: "brew install boost cmake glpk gsl gd mpfi ninja openblas pcre 
ppl r yasm zeromq"; I second this recommendation

Re: [sage-devel] Re: trouble upgrading to latest stable version

[Anne Schilling]

Thank you! I have homebrew installed. So I just do

brew install python3 ?

Installing the python package that Dima suggested did not help.
I am trying to avoid installing a new operating system right now since I 
anyway ordered a new computer.

Best,

Anne

Re: [sage-devel] Re: trouble upgrading to latest stable version

I agree, updating the OS if possible, and/or installing homebrew and 
python3 from homebrew would be the way to go.

Re: [sage-devel] Re: trouble upgrading to latest stable version

[Dima Pasechnik]

Hi Anne,
openssl is a never-ending problem on macOS, and in your case it's made
worse by an old macOS version.
One cannot expect much support and development on macOS 10.12, as it
has reached EOL in 2019.

One way out would be to install Python 3.7 from cpython, and then Sage
will just use it, without building.

https://www.python.org/ftp/python/3.7.7/python-3.7.7-macosx10.9.pkg

(or, alternatively, install Homebrew, then you can use many more
packages from there without building)

Hi Dima,

Thank you! I have run make distclean and now it gets stuck here:

https://www.math.ucdavis.edu/~anne/python3-3.7.3.p1.log

It looks like there is a problem with openssl.

Any idea?

[sage-devel] Re: Could someone point me to the code that supports math on symbolic equations?

[rjf]

It looks like you have written a recursive descent parser. And a display.
If you were running Maxima on a Pi, (see sourceforge for download)
you would have a parser and a display without writing it yourself.

  Just looking at the code briefly, I think you have to decide
if you actually meet your own specs.  I don't know what sympy will
provide, so maybe it is really OK.

For example,

a*b*c*d*e = a*g*c*d*f
divide by b*d  do you get

a*c*e = a*g*c*f/b  ?


or more seriously,  (x^2-1)/(x+1)   to get (x-1) ?

I would be surprised if you were the first person to write
a parser like this in Python, but it is a learning experience.

Good luck.

[sage-devel] Re: Could someone point me to the code that supports math on symbolic equations?

[Jonathan]

As promised here is a git repository 
 with a myBinder demonstration 
of what I have so far. Once I extend it to handling inequalities, it will 
more than meet my use case needs.

Some have asked for more specifics. Here is a list of some of the more 
important requirements:

1) Can be installed in a plain vanilla python3 virtual environment via pip 
or simply as a python file to be loaded.
2) Does not conflict with SymPy or NumPy.
3) Will load and run fast enough to avoid user complaints on a Raspberry 
Pi. One initial use case is being combined with Pi data acquisition 
hardware and python tools for controlling them.
4) Makes sense to scientists in the fields of Physics, Chemistry and 
Biology.

Thanks,
Jonathan

Re: [sage-devel] Re: Could someone point me to the code that supports math on symbolic equations?

[rjf]

You haven't provided enough information about your environment, but it is
generally feasible to acquire data in Maxima from a file or a socket or a 
stream.
Or compute numerical stuff, generate random numbers, read from a
keyboard, web page...etc.

Given that you are familiar with a particular programming language (here, 
Python)
that is not a symbolic math system your approach probably is structured as 
follows:

   Your (mostly already written?) python program
 does stuff  A 
  then somehow calls your symbolic math program as a subroutine on data 
B 
 then does something with the returned answer  C

.  There are a few questions here:  your program must format something
to be input to the symbolic math program.  It could be a string, or maybe
something that looks like a tree with pointers, or lisp list.  Any of these
forms may be tricky to produce correctly. You need to know about the 
symbolic math pgm.

Later, your program must receive an answer from the symbolic program.
Maybe it is just  "true"  or 43.  But if it is a symbolic expression, then
it is maybe a string or a tree with pointers.  Or maybe you are just
displaying it?? Anyway, you may need to know even more about the symbolic 
math pgm.

Generally, it may be tricky for your program to accept the answer.

(this is really a standard question for the ages --  
Physicist:  can you do symbolic math for me.

Computer scientist:   OK, we can compute "sin(x)*exp(x^2)"  
  What are you going to do with this in your Fortran program?
Physicist:  uh, evaluate it at x=.1, .2, .3 ...
Computer scientist:  you mean to call a compiler??  you can just
let the symbolic math program do the evaluation, write it into a file,
or just plot the curve directly..
Physicist: You can do all that?  But my program runs ... < excuses...>
)


So you are possibly committing yourself to writing a parser,
a string output display,  calling a compiler??? ... what else?

Here's another structure:

Start up Maxima and load a program that does "stuff A".   It might
even do "stuff A" by calling Python.  Maxima is written in Lisp,
and there are ways of calling Python.  Or the code could be
written in Lisp (compiled, maybe faster than Python?) or in the
Maxima language.

  Any of these languages can acquire info from a user, if
that is what is in your task. Error checking of symbolic
formula input is already written.

  Having done stuff A, the symbolic part is ready to roll..
What to do with the answer? 
 Whatever.   Maxima can decompose the answer, or display
it or write to a file ... If it is
necessary to run in Python, it is again possible to
call Python.  (And hand it a string or lisp/maxima structure).
If python is called,   It can return to Maxima, and Maxima can loop back
for the next iteration.

.
If you absolutely have to have Python as "the boss"  you could still do 
this:

Start up a python system that does almost nothing but initialize
Maxima and call it.
   Then use the structure outlined above.

For what it is worth, I have directly called python library routines
(interfaces to multiple-precision arithmetic, as it happens) from lisp.
Whether this approach is feasible is probably not a technical
question -- just depends on what you are comfortable doing.

It may be too late to consider this kind of change, and it may be
a bad fit for your application for some other reason.  In which
case maybe think about this for your next project.

If you insist on calling the symbolic math program as a subroutine,
perhaps the simplest interface is to invoke Maxima on some input
from a command line.  If your task is simple enough.

Re: [sage-devel] Re: trouble upgrading to latest stable version

[Dima Pasechnik]

Hi Anne,
it appears from your config.log that you did not do

make distclean

moreover, it says that R is already installed, and should not get
reinstalled.

Does Sage start? I guess not.
If before the latest git pull you had an oldish Sage (closer to 9.0 than to
9.1)
it appears that the build system is totally confused.
So you most probably need to do distclean.

Hi Dima,

I pulled the changes using git in the master branch and started make (or 
make distclean).
This is running on MacOS 10.12.6 .

Re: [sage-devel] Re: Have you considered having a Sage Journal?

[Ursula Whitcher]

It might also be worth looking at the Journal of Software in Algebra and 
Geometry:



https://msp.org/jsag/about/journal/about.html


Their current focus is Macaulay2, but as I recall, some of the editors 
have previously expressed interest in including Sage-based articles as well.

I have been thinking for a long time that the Sage Community

is going on with Sage; how it is being used in research,
education, etc.; what improvements have been made; etc., etc.,
etc. Perhaps an annual publication, so it is not so much of a
burden for the editors (?).

Since the *Global Virtual SageDays 109* is approaching (yay!!!),
it could be a good moment to discuss this idea with the community.
Actually, I can see that somebody already asked about how people
is using Sage in research, education, etc.

(https://ask.sagemath.org/question/51524/how-do-you-use-sagemath-in-research-education/)


That could evolve into a small journal with a few articles about
the use of Sage, if enough people collaborate.


There was actually a proposal like this quite a long time ago:

https://web.archive.org/web/20100615075428/https://www.sagemath.org/jsage/ref.html

The idea was to have a place where people could publish code in a 
refereed sense.  To my recollection, at that time there wasn't enough 
interest from academic departments (and perhaps still isn't) in 
awarding promotion based on such code.


Other groups do have such publications, e.g. the TuGboat 
(https://tug.org/tugboat/) for TeX or the R Journal 
(https://journal.r-project.org).  I think those that do may have an 
order of magnitude higher number of "power users", though.  But it 
would be great to have something like this for Sage.  An annual 
edition would seem reasonable, and certainly would be great for 
visibility/publicity (see the moribund 
https://groups.google.com/forum/#!forum/sage-marketing for one of many 
attempts at this).

Are you building from scratch?
What is your setup? (Sage nowadays supports building with Homebrew packages)

Yes, naturally, without the log files for R and dochtml one cannot say
what went wrong.
Also, the top-level config.log woud be useful.

[Furkan Semih Dündar]

Dear Anne,

I tried to compile the source code on Windows Subsystem for Linux (Ubuntu)
and could not go through the compilation process. Then I installed Fedora
32 as a separate OS. I installed all the packages listed on the following
website:
https://doc.sagemath.org/html/en/installation/source.html#prerequisites

Then I let my computer compile the source code at night, when I woke up it
was compiled successfully.

Hope this might help.

Best wishes,
Furkan.
