Re: [sage-support] simple desolve_tides_mpfr crash, even for SageMath Cell Server
Hello,
it requires the tides package (spkg) to be installed first of all. In a
console, try 'sage -i tides' and it should work.

Re: [sage-support] simple desolve_tides_mpfr crash, even for SageMath Cell Server
@slelievre
Thank you very much. I'm running in Windows using the binary installer (my
Linux box uses CentOS which seems complicated to compile SageMath with all
these dependencies that I need to compile manually as well).
The Sage shell in Windows state that I should not use sage -i ... to
install. How do I do this in Windows?
Best regards
Toan

I was thinking that too. I asked Andrey if it can be installed on SageCell:
https://groups.google.com/d/topic/sage-cell/kR4R_HJDrms/discussion
@[Toan T Nguyen]
To run this command on your own Sage, you first need to install
the optional package 'tides', which, depending on the OS and on
how Sage was installed, might be achieved by running:
sage -i tides
Running it on SageCell would require 'tides' to be installed there,
let's wait for Andrey's answer.
I tried installing on Ubuntu with Sage 9.1.rc0, it worked.
$ sage
Forcing sage-location, probably because a new package was installed.
Cleaning up, do not interrupt this.
Done cleaning.

Maybe SageCell doesn't have the optional package "tides" installed. This is
the same error I see on my own computer without "tides".

Thank you. It's an easy problem to reproduce. You can cut-paste that code
into the official online Sage Cell Server
https://sagecell.sagemath.org/
and see for yourself what I meant.

What do you mean by crash? Could you copy paste the *full* traceback

[sage-support] simple desolve_tides_mpfr crash, even for SageMath Cell Server
Hi all,
I'm trying to solve a system of 1st order ODE using desolve_tides_mpfr()
arbitrary precision module. My script crashes at the external gcc call.
So I try this very simple example I found from a tutorial in a website. It
also crashes at the same gcc call. I test it in the SageMath online cell
server, it crashes as well, so it's not just my code or my setup.
Could somebody help with this example? Is this a bug, or the script is
wrong?
Thank you
Toan
