[solved sort of] Program does not start

[metro]

I use a program that is not in the repository and have had only one issue with it in 3 years or so, see:http://www.pclinuxos.com/forum/index.php/topic,93206.0.html

I have an issue with the same program. In an earlier post muungwana showed me how to start this program from a terminal (was in readme with program)
I have posted on the runbasic Forum but its a bit quiet there and I believe its a linux problem not a software problem

I have opened a terminal as root and typed in "./rb101/rbp rb.im" (no quotes and as root ) and I get this error

[root@localhost laurie]# ./rb101/rbp rb.im
VisualWorks(R) 7.6 Feb 14 2008
Error: Can't open rb.im

usage: rbp -className -gui -guilib guilib.so -h bytes -ieeefp -l policy -noherald -v -xq -z bytes -? imagefile.im

usage: rbp [engine options] -=imagefile.im [image options]

as a normal user in a terminal or from the short cut I created 3 years ago the program hangs with no error message

as I have stated the program has worked fine for 3 or more years and only presented with a problem after an update a few days ago

I have just noticed in WebMin that the program has a Process ID
  4957    laurie    14:45    /home/laurie/rb101/rbp rb.im
so it is running but I have no GUI display

any help appreciated

A process ID doesn't necessarily mean it's running. It could be a zombie (a program that has closed in a messy way and is still in the process table). Use Ctrl+Esc on GUI or top in a terminal to check that.

Have you tried grep on the files in /var/log for rpm to see whether there are any messages there about the problem.

root's inability to open the file might simply be a permissions issue (though it is unusual for root to be denied access).

Additionally have you tried the simple route of "killing" the process(es) and restarting the desktop?

[metro]

thanks guys
I did manage to stop the process and I have checked all files in /var/log by using MC (midnight commander) and found no references to rbp or rb.im
I also created a new folder and installed a fresh download. then changed permissions for the new folder and files
even re -booted so not even the new version will start

but all no good......got me stumped think I'm out of my depth here
need to know how to trap of find error logs but not sure if all errors are stored in /var/log or is it possible they could be elsewhere

I spent the night creating a VirtualMachine running MintLinux
copied  the program via network to VM and program works as expected
I cant see how it can be a permission problem, can anyone shed some light on
any other way of looking at this

thanks in advance

Error: Can't open rb.im

please try as follow:

Code: [Select]

cd  rb101
./rbp  rb.im

running just fine here: (btw, in my case the directory is rb101free ... )

[metro]

Thanks AS
I have tried that and tried with full path, as stated above it works in a Virtual machine in Mint Linux
there is something blocking it on my system and i'm not clever enough to work out if the port is being blocked
or the program itself is being blocked by a firewall.....if so how do I find that out

thanks anyway

from a terminal as root I can see the process is running and listening ??

[root@localhost laurie]# lsof -i :8008

rbp     20898 laurie    7u  IPv4 929341      0t0  TCP *:http-alt (LISTEN)

I can see it in WebMin too, at a loss to understand where I look to see why the GUI is being blocked

what about to try to download the free version in a temp dir, and try again ?

[metro]

will try right now AS

results of download to tmp

Code: [Select]

[root@localhost tmp]# ./rb101free/rbp rb.im
VisualWorks(R) 7.6 Feb 14 2008
Error: Can't open rb.im

usage: rbp -className -gui -guilib guilib.so -h bytes -ieeefp -l policy -noherald -v -xq -z bytes -? imagefile.im

usage: rbp [engine options] -=imagefile.im [image options]

I tried from within rb101free too with ./rbp rb.im but it just hangs

as I've said earlier I copied the offending original folder unchanged to a Virt Marchine running MINT Linux and the program launched with no problems at all

I really don't want to re install, but its not lookin good

may be ... however you don't get the error anymore and to me it is just a confirmation that your original command is wrong:

Code: [Select]

./rb101free/rbp rb.im the above will never work, unless you move the file ./rb101/rb.im to ./rb.im ...

The fact it hangs ... may be ... or may be it is a display problem, because it seems from your previous report that there is a process listening on a tcp/ip port ...

Exactly which desktop are you running ? KDE, LXDE, ...  ?
Is your system fully updated ?

[AS]

From the README file:

Run BASIC Personal Server - Release notes

Installation under Linux:

Since we don't have an actual Linux installer for Run BASIC yet,
simply extract to a convenient folder.

Starting Run BASIC:

-cd to the Run BASIC folder
-Type ./rbp rb.im

Note: If Run BASIC hangs on startup make sure there are no other
 applications running on port 8008.

I would add that if an apps open a listening socket on a TCP/IP port, once you kill the process without closing it properly, the kernel will keep the port busy for a noticeable amount of time (may be 5 minutes ...), and therefore any next test will fail ... or as you may see ... just hang. (that's really depend from how is implemented the server ... )

Reboot your system and try to use the correct command from the first time.

Hi again AS

Ok, I have an updated KDE version of PCLinuxOS_2012 of 5 mins ago
I re booted once updated, then I started two Terminals and SU'd to ROOT and navigated to my original RB101 Folder
in 2nd of the terminals I entered "lsof -i :8008" this showed me that no programs where using port 8008
Then in Terminal (1) typed ./rbp rb.im to start RunBAsic
back to terminal 2 and I confirmed that rb was running and using port 8008 ( I think   )

[root@localhost laurie]# lsof -i :8008
COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
rbp     4908 root    8u  IPv4  18874      0t0  TCP *:http-alt (LISTEN)

Terminal 1 was hanging so i started WebMin and observed process 4908 was running and using 0.1% of the CPU and that the program was in fact ./rbp rb.im using that process
I am able to terminate programs from WebMin so I did just that and confirmed with Terminal 2 that the lsof -i :8008 to show the process had terminated

I then had a thought if .rbp rb.im was running then was it serving
so I repeated the above steps to get things running again

and then I  typed the following into Firefox address bar to see if  RunBasic works

http://localhost:8008/seaside/go/runbasicpersonal

       it does

So whilst the normal start up screen does not appear for some reason


The actual program starts and must immediately start serving....(not designed that way)

I will post on the RunBasic site to see if the Author of RB has any clues he can offer
but I refer back to my earlier comment the original setup works as expected after just simply a straight copy to a Virtual Machine on the same computer

This sounds as if the program is looking for the X server or the Display in the wrong place. Check the files in /var/log/ as root for clues.
