Problem with revMacFromUnixPath() at OpenStack

[kaveh1000]

I have a stack that has been working fine but I have made some changes and now there is a problem. It is a stack running in LiveCode 6.5.0 on mac, and not a stand-alone.

On OpenStack I need to set some paths. I have the following script:

put revMacFromUnixPath(the_full_path) into mac_path

the variables the_full_path and mac_path are both defined. The error I get on opening the stack is:

Function: error in function handler
Object [...]
Line put revMacFromUnixPath(the_full_path) into mac_path
Hint revMacFromUnixPath

If I comment out the command, open the stack, then run the command in msg box, it works fine.

I note from google pages (not allowed to post links here) that there is an issue in standalones, namely that this function may not be available before start-up of App is completed. So this might be related. I have tried to put it as late as possible in OpenStack, but still not working.

Any hints appreciated.

Hi kaveh1000,

yep, the problem is the way Livecode loads externals and its own libraries!
The are NOT YET loaded on "pre-/openstack" so you need to give LC a bit time to load them like this:

Code: Select all

on openstack
  send "fill_mac_pathnames" to me in 100 millisecs
  ## ...
end openstack

command fill_mac_pathnames
   put revMacFromUnixPath(the_full_path) into mac_path
   ## etc...
end fill_mac_pathnames

Know what I mean?
This way the libs have time to load and all will work out fine!


Best

Excellent, Klaus. I think it worked.
