[Windows] libedit-3.dll issues
When launching Rash, the following error message appears:
ffi-lib: couldn't open "libedit-3.dll" (The specified module could not be found.; errid=126)
I am using Racket v7.9.

Does the same thing happen with Racket v7.8? I think the version of libedit bundled with Racket was updated in this latest release. Do you get the same error when running a normal Racket repl?

Yes.

No. I can get into a normal REPL just fine without issue.
Huh. That's weird. Historically installing the readline-gpl package
(raco pkg install readline-gpl) fixes issues with the line editing.
Try that for now. I don't have a Windows machine handy to track this
down at the moment.

I'm not the OP, but I'm having the same problem. I don't see libedit.dll in my Racket 7.9 installation. (Unlike the OP's error message, my system does not find libedit.dll and not libedit-3.dll.) My Windows 10 system is version 2004 build 19041.388.
Instead of trying to fill in libedit.dll, I will try readline. So I install the package first.
%raco pkg install readline-gpl

That's just Portuguese for "The specified module could not be found.; errid=126)".
Put libreadline-5.dll in the same directory as rash-repl.exe.

This means "%1 is not a valid Win32 application; errid=193". I must have the wrong DLL for my system or something like that. I downloaded it from
http://gnuwin32.sourceforge.net/downlinks/readline.php
I suppose you wouldn't know what to do here? Thank you.

Sorry, I don't know. I'm afraid I don't have time right now to try to figure it out either. I don't use Windows, so it's harder for me to debug than Linux. My long-term plan is to replace the readline dependency completely with a line editor written in Racket. But I won't be able to do that terribly soon either since I'm busy teaching and wrapping up my PhD.
I believe the problem I have is that rash-repl.exe is a 64-bit application and I can't find a 64-bit version of readline. I believe we cannot mix two architectures in the same program.

Since I cannot find a 64-bit application, would it be much trouble for you to compile rash-repl.exe as a 32-bit application? I believe this would take care of things for me and, therefore, for practically all other Windows users --- having this exact issue.
But I know you're busy. If this is not just another command for compiling this desired version, don't worry about it. I can manage to eventually compile the right library version for the right architecture.
Thank you either way. I'm insisting because I think the software is great. I read your paper carefully in the last couple of days. Thanks for writing it.

Aha!

Did you install the 64-bit version of Racket? When you raco pkg install rash I assume it compiles it according to the version of
Racket you installed. Perhaps Racket is bundling the wrong version of
libedit? At any rate, I know some issues with libedit bundling were
fixed in Racket 8.0, so it might already be fixed for newer Rackets.
I don't actually distribute a pre-built executable, just a Racket
package definition which raco pkg knows how to build.
But I know you're busy. If this is not just another command for compiling this desired version, don't worry about it. I can manage to eventually compile the right library version for the right architecture.
Yeah, I'm not sure how to force Racket to build for a specific architecture, and I don't have time to dive into that right now. Sorry.
Thank you either way. I'm insisting because I think the software is great. I read your paper carefully in the last couple of days. Thanks for writing it.
Thanks! I hope to make time to make it better eventually!
Thanks for the info! I was able to build it by installing a 32-bit Racket 8.0 BC, the latest available on the website today. Any 32-bit version should do. I believe this might be almost required because it's not easy to find a 64-bit version of readline 5.0. (Unless one is willing to compile it oneself, which might not be too difficult, but I wanted to avoid the task.) I found a 64-bit version of readline 8.0, which does not seem to work with 64-bit rash-repl.exe.
For the future reader, here are the steps. Install 32-bit Racket, install readline-gpl (raco pkg install readline-gpl), then install rash (raco pkg install rash). In the output produced, you should [see] the path for your rash-repl.exe. For 64-bit versions, you'd be better off compiling readline by yourself and I'd choose version 5.0 because version 8.0 doesn't seem to work and I am not confident readline 6.0 would, although the closer to 5.0 the better --- I suppose. Good luck!
William, you can close this issue if you'd like. Thank you again.

Cool, I'm glad you found a solution, and thank you for posting it!
William, you can close this issue if you'd like. Thank you again.
I think I'll leave it open until I resolve the line editing solution, because people keep having problems like this. So leaving the issue open will hopefully give the solution more visibility.
