<div dir="ltr">Hello all,<div><br></div><div>I am trying to open an xcrysden window on my windows 10 machine though CygWin. After opening a cygwin terminal, I ssh to a linux machine where I have xcrysden installed and as far as I understand I should be able to just run xcrysden? However when i prompt the window I get the following error:</div><div><br></div><div>%%</div><div><div>XCRYSDEN_TOPDIR=/usr/share/xcrysden</div><div>XCRYSDEN_SCRATCH=/tmp</div><div><br></div><div>Application initialization failed: no display name and no $DISPLAY environment variable</div><div>Error in startup script: can't read "xcrys(platform)": no such variable</div><div>Â Â while executing</div><div>"if { $xcrys(platform) == "windows" } {</div><div>Â Â # testing ...</div><div>Â Â rename exec _tcl_exec</div><div><br></div><div>Â Â proc exec {args} {</div><div>Â Â Â Â global env</div><div><br></div><div>Â Â Â Â # first try a normal exec..."</div><div>Â Â (file "/usr/share/xcrysden/Tcl/cygwin.tcl" line 19)</div><div>Â Â invoked from within</div><div>"source $system(TOPDIR)/Tcl/cygwin.tcl"</div><div>Â Â (file "/usr/share/xcrysden/Tcl/xcInit.tcl" line 443)</div></div><div>%%</div><div><br></div><div>It seems like the problem could be resolved by setting the environment var $DISPLAY however I am not positive what to set it to?</div><div><br></div><div>I have seen some documentation that states that some auxiliary programs should be installed such as Tcl, however it is not 100% clear whether these should be installed on my linux machine that I am ssh'ing to OR if they should be installed in my cygwin terminal?</div><div><br></div><div>Best,</div><div>Cameron</div></div>
