externals in LiveCode vs RunRev

[OBDave]

Hello - I have been using RunRev 4.0 on and off for a year or so and decided to give LiveCode 4.6.2 a try. Right off the bat I'm having problems calling external functions. Have the rules for eternal calls changed? Searching through the forums and Google didn't yield anything. The issue is that RunRev calls to functions that reside in a external were OK, but under LiveCode, the function call is flagged with:
card "MainCard": execution error at line 88 (Handler: can't find handler)

If somebody could point me in the right direction I'd be most appreciative.

Thanks,

Dave

Did you set the folder properly in the preferences?

[OBDave]

By that, you mean the "User Extensions" setting in Preferences... Files & Memory? Setting that did not resolve the issue.

Interestingly enough, this was never set in RunRev 4.0. But your suggestions jogged my memory. When I set up RunRev 4.0, I had to go into the Run Rev application folder and add my external .bundle and .dll there, so I tried doing this with LiveCode and it seems to have resolved my issue.

Thanks very much for the reply!

There is a format to the user extension folder.. We will use "/" to mean the root of the user extension folder (os on my computer that would translate to /shaosean/Documents/My Revolution Enterprise/ )

/Externals
/Externals/Externals.txt
/Plugins
/Resources
/Resources/Icon Libraries
/Resources/Object Libraries
/Resources/Script Libraries (I think this is part of the default folders that rev uses)
/Runtime (best to copy the folder from the application and remove all the files, but keep the folder layout)
