Four Js Customer Forum

Good day,

I have a program with several modules.  I added a new function to one of the modules and recompiled.  Now I get a runtime error:--

QuoteDate: 08/11/2013    Time: 10:36:40
Program error at 'U_security.4gl', line number 0.
FORMS statement error number -6208.
Module 'U_security': already loaded.

I have tried deleting all the *42* files and then recompiling.  the recompile/link is successful, but I still get the runtime error.  The module in question is linked once only.  Any ideas?

Thanks,
Mark

Hello Mark,


May I ask you the Version of Genero please ?  (the output of the command : fglrun -V)


Thank you,

Hi!

I would do as follows:

1) verify it I don't have two different funcions with the same name in 2 distinct 4gl files
2) check if the 4gl file that contains the function is not used on two differente 42x libraries
3) check for duplications on the make file or Stdio dependencies.

But same more details about your program would help!

Best regards
Nuno

Thanks for the response.
1) I've checked that, and there are no duplicate functions.
2) It isn't used in any 42x libraries.
3) No duplications.

Another program that uses the same module produces the same error.

What details do you need?

Regards,
Mark

The details I would ask you would be the dependencies list or, if it is still the case, your makefile.

Why don't you try to remove the file from your dependencies and the re-link to see if you get an error message of missing functions ?

Hello Nuno,
your problem happens in a small program - fortunately.
If you trust me: please mail your sources (don't forget a potential .sch file).

The error -6208. is a "can't happen" error: Should never happen with a legal 4gl source. This is an indicator for an internal error in the runtime.

One question: Do you get the same error when starting the debugger (before calling 'run')?

A thought has occured to me: if there's a program running that is using this module, i.e. the 'old' version, could that produce this error?

Hi!
I think Rene message was meant to Mark, but thank you any way.

Hello Mark,

>> A thought has occured to me: if there's a program running that is using this module, i.e. the 'old' version, could that produce this error?

This can cause a problem when running on Windows. Only on windows.
When running on Windows, disable mmap (sharing the byte code): add this in in fglprofile:
fglrun.mmapDisable = true

On the other hand: the compiler can not write the new .42m if the module is already loaded (again: windows only). fglcomp should throw an error in that case.

Also: please replace "fgl2p" in your makefile. The command to compile is "fglcomp". The command to link is "fglrun -l".

PS: if this does not help: Mark, you can mail me the sources...

Hi Mark.
I've comparing your makefile with my own makefiles and I found no error on it! I'm out of ideas. So sorry...
Anyway, when dealing with makefile small errors, like spaces instead of tabs, are allways to consider.
In the hope it can, somehow, help you, I'm sending you, as an attcement, one of my makefiles. Maybe you can give it a go...
Best regards
Nuno

Thanks for your help.  I didn't think the error would be in the makefile, since that is unchanged.

Hi Rene, that didn't work.  Can I mail the source to you privately?  I don't want to post it on a public forum.
