Re: [Swarm-Support] Followup: found work-around for missing ~/swarmarchiver.scm too

[Pietro Terna]

        Hi Paul and all,

        a few notes about Paul’s communication reported below.

1.

Using the rpm distribution for Fedora 5 we have 
also problems in instance creation via lispAppAchiver:

e.g. "heatbugs –b" (for batch execution) fails.

In ObjC we can fix the problem as follow (//pj 
line is from Paul’s suggestion below; //pt one is mine

(file main.m of heatbugs)

int
main (int argc, const char **argv)
{
  id theTopLevelSwarm;

  // Swarm initialization: all Swarm apps must call this first.
  initSwarm (argc, argv);

 lispArchiver = [LispArchiver create: globalZone 
setPath: "/home/terna/.swarmArchiver.scm"]; //pj
 lispAppArchiver = [LispArchiver create: 
globalZone setPath: "heatbugs.scm"]; //pt

2.

The .swarmArchiver.scm file created in the way 
above is not standard, lacking a part of the 
Scheme expression, with the application name etc.

3.

I tried to introduce the same correction also in 
jheatbugs (the Java version has the same init 
problems). Look at the lines below (//pt lines are mine)

(file StartHearbugs.java)

import swarm.Globals;
import swarm.defobj.LispArchiverImpl; //pt

public class StartHeatbugs {

    public static void main (String[] args) {


       Globals.env.initSwarm ("jheatbugs", 
"2.1", "address@hidden", args);

       Globals.env.lispArchiver= new LispArchiverImpl(Globals.env.globalZone,
                                           "~/.swarmArchiver.scm"); 
//pt 1
       Globals.env.lispAppArchiver = new 
LispArchiverImpl(Globals.env.globalZone,
                                                           "jheatbugs.scm");//pt 
2

the '//pt 2' correction works perfectly; the 'pt 
1' has no effects, as something had gone definitively wrong in the init step.

        Yours, Pietro
