Strange behaviour of Coco/R

[dmaksimiuk]

Hi All,
I am in the process of transition from the BBox 1.7-a1 to the BBox 1.7.1-rc1 environment. I have installed the Coco/R - Compiler-Compiler V2.2-9 on both systems.
On version 1.7-a1 everything works fine.

During my experiments I have encounter a problem with the Coco/R on the 1.7.1-rc1. It compiles an *.atg file with my language definition, but it fails to display FIRST and FOLLOW sets, and any other sub-function from the tool's menu. It gives me the following messages:
Item guard CocoCRTasks.NotEmptyGuard for CocoCRT.ListFirstAndFollowSets not found
Item guard CocoCRTasks.NotEmptyGuard for CocoCRA.PrintStates not found
etc.

Any idea how to fix it?

Darek

Did you compile both Coco/R separately for both installations of BlackBox?

It gives me the following messages:
Item guard CocoCRTasks.NotEmptyGuard for CocoCRT.ListFirstAndFollowSets not found
Item guard CocoCRTasks.NotEmptyGuard for CocoCRA.PrintStates not found
etc.

Module CocoCRTasks is a custom interface. Coco provides a template only. You have overwritten and destroy Coco with your project.
Coco itself uses CocoTasks. There are your missing procedures.
Solution: Unpack Coco from the save set and reinstall Coco via the Quick-Start instruction.

Hi Ivan,
Yes. I did compile Coco/R on each system separately.

Hi Helmut,
I did a set of experiments with Coco/R installations.
On both system I have used the StdCoded file as a source for installation process.

Then, I have compiled source code, and compare sizes of the object files on both systems. They are the same.

After updating and compiling the Config.odc, I have re-started the BBox environment and on:
- system 1.7-a1 STOP working - the same error as on the 1.7.1-rc1
- system 1.7.1-rc1 still got the same errors

When I have upgraded my Coco/R from 2.2.8 to 2.2.9 on the 1.7-a1 system probably I did not delete all Sym files....

I have re-installed version 2.2.8 on both systems and it seems to be working fine.

Sorry, I don't understand the problem.
I install Coco on 1.7-a1 and it works
I install Coco on the 1.7.1-rc1 and it works

that is the point. the old sym,and code files need to be deleted, and recompile it, reload it. I have met this problem several times.

I did the following experiment:
- Completely fresh installation of 1.7.1-rc1 on a different machine without any other components installed (Win7, x64)
- Coco/R from Helmut's web resources (2.2.9).
- Sources have been compiled as described in the Quick-Start document.
- BBox restarted.
- Copied my experimental *.atg file to that machine.
and
- compilation WORKS
- execution of any other items gave the same error as on other laptop

Is there anything stored in Windows registry that might be related to my problems?

Thanks for your time.

The installation command in the CPC package does not include recompiling CocoCRTasks etc.
If you want to recompile everything in subsystem Coco you can use the command

(!)DevCompiler.CompileSubs Coco ~

or you can recompile the missing files (CocoCRTasks, CocoCRCmds, CocoTextsOV4) one by one.

No, the Windows registry entry doesn't relate to your problem, but the menu entry.
Change in the menu all guard entries from "CocoCRTasks.NotEmptyGuard" to "CocoTasks.NotEmptyGuard"
Sorry for the error in the save set
