"luac" for Mac OS 10.15 (Catalina)

[Repost from 8/26/2019]

It appears that "luac" version 5.1.4 on Mac is 32-bit and thus won't run in Mac OS 10.15 (Catalina):

$ file `which luac`
/usr/local/bin/luac: Mach-O executable i386
$ luac -v
Lua 5.1.4  Copyright (C) 1994-2008 Lua.org, PUC-Rio

Possibilities for handling this:

1. Find a version compiled for 64-bit.  (I haven't found such a version so far.)

2. Try to recompile the sources for 64-bit. (Ugh -- something will surely break, likely in a nasty way?)

3. Keep a virtual machine around running Mac OS 10.14.

4. Compile my plugins within my Windows virtual machines.

What are others doing?

And why are you posting this on the Adobe LR Classic forum?

Shouldn't you be posting over on forum that deals with that compiler?

Unfortunately, the Lightroom Classic SDK forum has been merged into this one, with its old posts tagged with the topic "SDK":

The post above was one of the ones in the window 8/22 - 9/11 that were lost in the transition.

John I didn't realize it was your post. I would of passed it by if I had. Sorry.

No worries. Today is just the start of the confusion...

Jeffrey Friedl kindly provided "luac" (5.1.2) that he rebuilt for 64-bit:

LR is built with Lua 5.1.4, but since Jeffrey's plugins are among the most widely used, I think we can be pretty confident that his 5.1.2 "luac" works just fine.

Adobe indicated to me that they may include a 64-bit "luac" in the next major version of the SDK, coming out later this fall?
