I am using Cygwin on a windows XP system. I installed iraf but have not been able to open an xgterm window. I can open an xtern window. I am unsure if I have installed the correct X11iraf package as there does not seem to be a cygwin version. I loaded the macintel version but this was unhappy with the system being cygwin and not macintel. This install also needed the user to be root but my cygwin installation does not have a root user rather it has system. I am unclear how to correctly install a version of x11iraf on my system. Any advice would be appreciated.

A binary for XGterm is available at https://iraf.net/ftp/pub/fitz/xgterm.cygwin A full X11IRAF build is pending but since XImtool is limited by 8-bit displays at the moment DS9 is the preferred image display for XP (see ftp://sao-ftp.harvard.edu/pub/rd/ds9 for a binary). To use xgterm, just be sure the file is executable and in your path.-Mike

Thanks Mike That worked fine.

Firstly, apollogies for resurecting an old thread. If this is unacceptable please let me know and I'll happily start a new one.Secondly, I have a problem (of course!<g>. I followed the CygWin/IRAF installation instructions given here: <http://www.iac.es/sieinvens/siepedia/pmwiki.php?n=HOWTOs.IrafCygwin>All is fine, except running DS9 appear to do anything. Same with executing 'xgterm -font lucidasanstypewriter -sb -ls&' (and variations thereof). X11 appears to startup ok and I can start as many xterm sessions as I like. Any suggestions?Regards

Revisiting old threads is fine if the problem is similar.Do you get any kind of error message at all? A 'command not found' might simply mean your path doesn't include the /usr/local/bin directory where you might have installed these commands or the binaries aren't executable, a complaint about the X server may mean you didn't define a 'DISPLAY' environment variable (but then xterm would fail as well). Does the command 'which xgterm' correctly find the binary? Is there any output at all?-Mike

Thanks for your reply.Nope, no error messages at all after running DS9 or xgterm. The 'which' command finds xgterm and ds9 in '/usr/local/bin'. Running 'echo $DISPLAY', from the bash shell returns ':0'. From xterm it returns ':0.0'.Unlike 'peters' I have not attempted to install XIRAF. I have only installed the basic CygWin X11 components, including the Adobe fonts and xeyes (I like them Regards

Hi,Actually my last post was not strictly true! Running 'startx' produces three identical warning messages: 'Warning: Cannot convert string "nil2" to type FontStruct'. Not sure how relevant that is, but thought it should be mentioned.Regards
Robin

Hi,Got DS9 working. Downloaded the latest version, installed to default location, recreated link in /usr/local/bin and it worked just fine.Still cannot get an xgterm window to appear though - nuts!Regards

Are you using XP or Vista? If you type 'xgterm' from a Cygwin window or xterm and [b:155fb72cc6]don't[/b:155fb72cc6] run it in the background, does the prompt come back or does the app look likes it's running and doing something? If you specify DISPLAY to be another machine, does it work (i.e. is the app not starting or is it a problem with the display?)-Mike

Hi,OS is WinXPPro SP3. CygWin newly installed 23Dec2008 (built on a new hard drive).Running 'xterm' from the Bash shell generates "xterm Xt error: Can't open display: :0"Running 'xgterm' from the Bash shell locks up the shell. I can see the xgterm process in Windows Task Manager.Running 'xterm' from an X11 window creates another window (as expected).Running 'xgterm' from an X11 window locks the window. I can see the xgterm process in Windows Task Manager.I'm not seeing an .XResources file anywhere! Does that matter greatly?
Anything else I should try? Currently trawling the net looking for xgterm info, but not finding much.Regards

Try starting as[code:1:8e54dfab3c]% xgterm -display :0.0[/code:1:8e54dfab3c]I suspect your DISPLAY may not be being picked up properly. If that doesn't work, then try both of[code:1:8e54dfab3c]% xgterm -ls
% xgterm +ls[/code:1:8e54dfab3c]These start the window as a login shell, and then as just a plain shell respectively. Something in your .login file or other startup may be causing the system to wait for something, the latter command will ignore your .login so if that works but the first one doesn't, please post your .login file (if you have one). Either way, let me know if these change anything.-Mike

Hi,Sorry, but none of those worked .I don't have a .login file but I do have .bashrc file. I have also listed the XWin.0.log in case it is useful. I'll try and resolve the TTF and OTF font issues noted in the log file.************************************************************

Robin,I'm starting to run out of ideas: Your .bashrc file is mostly commented out and what is defined doesn't actually do much. The complaint about a 'nil2' when starting X is probably coming from some resource setting for the xterm menu, it shouldn't however be fatal.An unlikely explanation may be a corrupted binary, i.e. if you clicked the link on the web page and let the browser do the download it might not have used binary mode or set the permissions properly. You might try downloading again by typing the wget command entirely to see if it makes a difference. Until this gets sorted you can always use xterm as the window (just be sure to set xterm as the terminal type when you do a MKIRAF).-Mike

Hi,Thanks for all your sugesstions thus far. I'll try using wget to reinstall xgterm again; although that is how it was done the first time. After that I'll go with the HEASoft folks sugesstion of downloading the entire CygWin installation (bit like using a sledgehammer to crack a nut though!). After that I'll go to a completely new machine and redo the whole darn thing from scratch!!! Patience is a virtue in astronomy (or hospitals<g>.Regards
Robin

I installed the whole CygWin X11 section and xgterm now works - YIPEE!!!
Of course that means I have no idea what fixed it - NUTS!Now on to the IRAF tutorial stuff :-DRegards
Robin

Oooops!!! I meant HEASARC of course!Now happily working my through several IRAF tutorials found on the 'net.Regards
