How can I know whether ODCL Runtime is installed or not ?

[khann]

Hi,
When I published a lisp code of involving ODCL Form or Function ,
if he does not have ODCL Runtime the lisp code will fail.

At this time can I check the Runtime is installed or not before run the lisp code ?

Thanks.

Hi, I didn't test it yet, but I would give it a try:
(vl-cmdf ...) executs a command without cancelling the code in case of failing

Code (autolisp) Select Expand

(if (and (not dcl_project_load)
(vl-cmdf "OPENDCL")
(not dcl_project_load))
  (alert "No OpenDCL is installed yet.")
); if

The more complicated way would be to research the registry.

The ideal approach is to run the OpenDCL Runtime install as part of the installer for your own code, then there is no need to check for its presence.

Yes, that's right.
I make some codes of install program, some codes of just ".lsp" file which has ODCL Function.
Install program has ODCL Runtime but the others not.

I don't know who will get my codes by chance and run on his machine after it's been published.
So I want to check the ODCL Runtime is installed or not and just alert him of ODCL presence if he has not ODCL Runtime.

Thanks, Owen.
