Serial with OSX Leopard
Oct 27^th, 2007, 6:37am

I just got a copy of Leopard, and I can't get the serial library to work. Maybe someone can help me out. I get the following error.

check_group_uucp(): error testing lock file creation Error details:Permission deniedcheck_lock_status: No permission to create lock file.
please see: How can I use Lock Files with rxtx? in INSTALL
gnu.io.PortInUseException: Unknown Application

at gnu.io.CommPortIdentifier.open(CommPortIdentifier.java:354)

i tried to run the "macosx_setup.command" script but i got this error:

sudo: niutil: command not found
sudo: niutil: command not found

Hopefully someone can help me out. thank you

Could you type down how you made it work, step by step and where I find the folders you mentioned? Previously I used... sudo chgrp uucp /var/lock sudo chmod 775 /var/lock ...to make it work, but it doesn't seem to help under Leopard. Thanks!

No problem... here you go.

1. Under Finder click on the "Go" Menu
2. Select "Go to Folder..."
3. Type "/var/"
4. Finder will open var folder.
5. Right click on folder named "lock" and select "Get info"
6. Open drop arrow titled "Sharing & Permissions"
7. I set all privileges to: "Read & Write"
8. Close Info
9. Go to the Var folder on the finder and open the "spool" folder
10. Right click on folder named "uucp" and select "Get info"
11. Open drop arrow titled "Sharing & Permissions"
12. I set all privileges to: "Read & Write"
13. Close Info
14. DONE

This is what i did to make it work, I am not sure what impact it might have on security by setting these to read & write, but at least it allows the serial library to work.

Let me know if it worked for you. Good luck!

But I had to run the macosx_setup.command first, then go back and fix the permissions. But for the record, dscl can be used instead of niutil. Just a heads up for those of us who lost it in the upgrade to the new cat.

I am alternating between two errors.

After i run the macosx_setup.command, "everyone" is set to Read only in /var/lock. I notice in the terminal that the group for these perms is _uucp, not uucp.

In that state, I get this error:

Stable Library

Native lib Version = RXTX-2.1-7
Java lib Version = RXTX-2.1-7

check_group_uucp(): error testing lock file creation Error details:Permission deniedcheck_lock_status: No permission to create lock file.

Then, according to bacadd, I hand edit the "everyone" permissions for /var/lock/ to Read and Write (note /var/spool/uucp is Read/Write in all cases, and doesn't change). I get this error:

From the RXTX guys:

Hi,

You will need to get the 2.1-8 code from CVS. See the FAQ for more
information:

http://rxtx.qbang.org/wiki/index.php/FAQ

Andre

I downloaded the development code (2.1-8).
I copied the resulting librxtxSerial.jnilib and RXTXcomm.jar into the /libraries/serial/library/

Yet I still see this on Processing:
Native lib Version = RXTX-2.1-7
Java lib Version = RXTX-2.1-7

fry YaBB Moderator Offline Posts: 2623 mass, usa	Re: Serial with OSX Leopard Reply #10 - Nov 17^th, 2007, 4:12pm great, thanks. will do that.
