Cincom VisualWorks on headless Intrepid Server

Hello,

I have exhausted my typical guru friends on this question, although I only did their instructions, as I could not give them access to my server itself. I am trying to set up Cincom's VisualWorks on my server so I can deploy my smalltalk programs on it. If you have used VisualWorks before, you will know that it heavily relies on X. The program copies by copying a directory /vw7.6nc/ to somewhere on your server. The program works on my other computer with:

Code:

/usr/local/vw7.6nc/bin/linux86/visual /home/bryanjp/demo.im -headless

On my laptop, I can run the VisualWorks in headless mode but when I try to run this on my server, which does not have X, I get following error message

Code:

bryanjp@bryanserver:~$ ls -l /usr/local/vw7.6nc/bin/linux86/
total 5228
drwxr-xr-x 2 root root    4096 2008-12-21 14:12 assert

-bash: /usr/local/vw7.6nc/bin/linux86/visual: No such file or directory

Can anyone explain why this is happening? A guru I know recommended strace, and he told me its a problem with the X libraries, but I don't know how to interpret it.

Code:

bryanjp@bryanserver:~$ strace /usr/local/vw7.6nc/bin/linux86/visual /home/bryanjp/demo.im -headless
execve("/usr/local/vw7.6nc/bin/linux86/visual", ["/usr/local/vw7.6nc/bin/linux86/v"..., "/home/bryanjp/demo.im", "-headless"], [/* 19 vars */]) = -1 ENOENT (No such file or directory)
dup(2)                                  = 3
fcntl(3, F_GETFL)                       = 0x8002 (flags O_RDWR|O_LARGEFILE)
fstat(3, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 0), ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7ff260f43000
lseek(3, 0, SEEK_CUR)                   = -1 ESPIPE (Illegal seek)
write(3, "strace: exec: No such file or di"..., 40strace: exec: No such file or directory
) = 40
close(3)                                = 0
munmap(0x7ff260f43000, 4096)            = 0
exit_group(1)                           = ?
Process 5113 detached

Any ideas are welcome! Thank you.

This is the last bump I am going to do, I promise, but I would really appreciate some help.

Start your app like this:

visual -NOLOGO myImageHere.im -nogui

That will startup with no UI hooks. You'll have to make sure (using a subsystem is the easiest way) that your application starts up when the image starts. For more tips, visit Smalltalk Daily - which I can't post the url to (the site blocked my attempt) - just Google it. Also Google for the Cincom Smalltalk Website for more help.

You can also see Smalltalk Daily by visiting my blog - again, Google me (James Robertson) to find that.

Hi James,

I've since tracked the problem down using strace to ENOENT being the return. This is only returned when the file doesn't exist, or a library is missing. In my case it is a library missing. I also found that running the 64 bit VM does work, but I haven't had time to convert my code to the 64 bit VM. Again thank you!

Also, I am a HUGE fan of your smalltalk daily. I love watching them and it seems like everytime I have an issue, it is answered with your Smalltalk Daily
