I tried running IronScheme.Console with the -emacs ‘flag’ from the console. I got the following error:

Unhandled exception during evaluation:
&assertion
&who: “open-input-file”
&message: “Could not find file ‘c:\\Program Files\\IronScheme\\-emacs’
.”
&i/o-file-does-not-exist: “-emacs”

I’ll state the obvious here and say that it looks like it’s interpreting that flag as a file.

Note: I uninstalled/reinstalled the latest ironscheme/xacc.ide when trying the above.

I also had a friend check this on windows server 2008 64bit. He received the same error.

I had UAC disabled, he had UAC enabled.

Some observations:
1. Turn UAC off (I will look into this sometime)
2. Modify xacc.ide.exe.config, to point to Program Files (x86) (not sure if this is needed)
3. change the argument in xacc.ide.exe.config to ‘-emacs’.

The good news is that it does work. The bad news is on my VM it takes a long time to start, more than a minute. This is related to IronScheme and not xacc.ide, and perhaps a VM only issue (due to lack of RAM). I also noticed that it eats up to 200MB of RAM during startup, then drops eventually to about 45MB.

I did not however experience any of the problems that was noted.

The other good news is that it passes all the same tests as the x86 version. It can also rebuild itself Both of these didnt take too long. Not sure what the problem with the startup is. Guess I’ll have to use a fresh drive and install directly on PC to test.

Over the weekend I’ll upload a new installer for xacc.ide (not sure if older NSIS has an effect). IronScheme 1.0 beta 3 will also follow soon

I will test on Vista 64 tonite, to see what is causing the aforementioned issue.

Also, I have some intentions to amalgamate IronScheme and xacc.ide, into a decent Scheme IDE.

Good luck with SICP. Just ask if you get stuck, and feel free to share your experiences

Also, your scheme implementation hits the sweet spot for me. I will be going through the ‘Structures and Interpretation of Computer Programs’ course with it.

Thanks for providing such useful software!

Will try install my Vista64 on a VM to see if I can determine the issue.

This issue has been fixed in changeset 25893 and will be in the new release.

For the source code, you can download it from here:

when I select menu view – ironscheme shell, this message apperars :

Is this serious?
