Aloha folks!I've recently installed IRAf on Cygwin following the instructions laid out by IAC (used by others on the forums) and I have encountered an error upon starting IRAF.
Xgterm and DS9 start fine but upon issuing the ecl command I get the error:ERROR: syntax error
called as: `cl ()'
called as: `cl ()'
Error while reading login.cl file - may need to rebuild with mkiraf
Fatal startup error. CL dies.I have backtracked through the forums and checked over the extern.pkg file to see if there was a misplaced / but no joy.
I followed the installation instructions to the letter and I'm stuck at this error. Everythings else seems to work fine.Any ideas folks?Mahalo

The error can only be in your login.cl or loginuser.cl file, or the system $hlib/extern.pkg file. You can do a new MKIRAF to recreate your login.cl file, and temporarily move your loginuser.cl file so it won't be read to rule them out. For the extern.pkg file, a space after a '\' or something similar could cause an error. Some editors fail to put a newline on the last line of the file which also causes a parser problem but if you can't spot it feel free to post the file, or else comment out every line to verify that is the file with the problem and then gradually uncomment lines until you find the problem.Lastly, you should just need to type 'cl' to start, the ECL is the default.

Ok.. I have two extern files. One is extern (pkg file) and the other is extern.pkgThis is what they look like:# External (non core-system) packages. To install a new package, add the
# two statements to define the package root directory and package task,
# then add the package helpdb to the `helpdb' list.

Sorry for the uber-long post.

I don't know what you mean by the first 'extern' file .... Anyway, try putting the lined_traceas the first line in the login.cl file. It should give you a clue where the error is, if not post the last 20-30 lines of output. The files you posted look normal.

Thanks for the help fitz,Will the output be given in the xgterm window or in the cygwin dialogue box?

In whichever window you are in when you type 'cl' (which should be the xgterm window)

hmm.. okay I've placed d_trace at the top of the login.cl file and I'm not getting any extra output in the xgterm window, just the usual error message about the CL dies.Should d_trace work on it's own within the xgterm window? If I type d_trace it says 'command not found'

d_trace isn't producing anything in xgterm but I did get an arror in the cygwin dialogoue box:3 [main] xterm 7248 child_copy: linked dll data write copy failed, 0x34C00
0..0x34C03C, done 0, windows pid 2340, Win32 error 487
xterm: Error 29, errno 11: Resource temporarily unavailable
Reason: spawn: fork<> failedThis is the first time I've seen this when running startx.Any ideas? Shhould i do a clean install?

The last message would be a problem in Cygwin or the X11 install, not iraf. You can start IRAF from the cygwin terminal window just to verify that it works but can't use if for graphics. Otherwise, try using the 'xterm' that comes standard so you're not confusing possible problems with the xgterm.The 'syntax error' looks like it's coming from the CL, the only file read before your login.cl is the $iraf/unix/hlib/clpackage.cl which you should never need to touch, but verify that it is there. This is also the file that loads the extern.pkg file so an error in extern.pkg would cause the error before your login.cl gets read. Lastly, if you've updated to Windows note that none of this has been tested on that platform yet. Otherwise, could you post a reference to the "instructions laid out by IAC" in case there is some non-standard recommendation in there.

Ok I tried starting IRAF from Cygwin and and it gave me the same cl syntax error.
Here's the link to the IAC instructions: http://www.iac.es/sieinvens/siepedia/pmwiki.php?n=HOWTOs.IrafCygwinI also verified that the clpackage file was present and it is.The code used in the extern.pkg file is located at the bottom of the IAC instructions. There may be an error in the formating but I am not experienced enough to spot it, sorry.
