| Post subject: | esingular fails to launch |
Hi, I am new to using singular and just installed the package through cygwin64. However when I try to launch the esingular by typing in the cygwin64 terminal : esingular, I get the following error: "Error: Can't find emacs or xemacs execuatble. Expected it at /usr/bin/emacs or /usr/bin/xemacs. Specify alternative with --emacs option, or set ESINGULAR_EMACS environment variable" I have tried to place the .emacs-singular file which is in the folder :home\Singular4\share\singular\emacs to the folder where Esingular is installed. However I still get the same error that it can't find the executable. any advice would be much appreciated. Thanks, Victor |

As the message suggests: you are missing the program emacs and the program xemacs: install at least one of them depending on your personal preference (which we do not know). Probably an X-Server is also needed, see http://x.cygwin.com/docs/ug/using.html for install hints, |

emacs is installed on my cygwin. I can open emacs from the cygwin terminal. However I can't open esingular. Seems like I need to add path to emacs somewhere in the Singular? I don't know where. I have re-installed singular from binary or the source code. Still, esingular doesn't launch. Any ideas? |

Please check that - emacs is with your path (which emacs resp. type -p emacs should return a non-empty string) and really called emacs (resp. emacs.exe) (and not emacs-24 or similiar) - the place of emacs.ex is /usr/bin (or add a corresponding setting to your .bashrc: export ESINGULAR_EMACS=/place/of/emacs.exe) - emacs is emacs from cygwin (otherwise the signal processing for the communication will fail) |
