Sage under Cygwin64

[Miguel Karlsruhe]

Hi group,

Running 'make' of Sage-8.8-Ubuntu_18.04-x86_64.tar.bz2 under Cygwin64 shell (Windows 10), I get the following building error:

The build directory may contain configuration files and other potentially

Any help? Thanks a lot,

install gcc, g++, gfortran packages from your Cygwin64; you also don't need to build zlib, Sage can use the installed zlib, as well as many other.

None of this is relevant to the OP.  Please read carefully:

Miguel, you are trying to run a Linux binary on Cygwin.  That won't work, and it isn't how Cygwin works--it cannot run Linux binaries.  It *does* work in the Windows Subsystem for Linux (WSL) shell, if you have that installed.

What are you actually trying to do?  Providing any further advice would depend entirely on that :)

Miguel,

Installation options under Windows 10 include the following three:

- activate Microsoft's "Windows Subsystem for Linux" (WSL);

  for that, provided you have admin rights on that computer,

  follow the official instructions at

  https://msdn.microsoft.com/en-us/commandline/wsl/install_guide

  Then, install Linux in the WSL, and either use SageMath binaries

  for Linux as found on the download page at

  http://www.sagemath.org/download-linux.html

  or install from source in that Linux environment.

- use Cygwin and build from source; for this follow instructions at

  https://trac.sagemath.org/wiki/Cygwin64Port

- use the SageMath installer for Windows (aka "Sage-Windows");

  see documentation at

  https://wiki.sagemath.org/SageWindows

  This installs a Cygwin layer and a ready-to-go SageMath in it.

  It puts startup icons on the Windows desktop for running either

  - SageMath in the Jupyter Notebook server

  - the SageMath REPL (or read-eval-print loop),

    also known as the command line interface,

    or "Sage in the terminal"

  - the Sage shell, a terminal window where one can type in

    commands to install extra packages for Sage or Cygwin.

Kind regards,

Samuel
