Red Hat Enterprise 5 dgnc wont compile

Hi all,

I am trying to install the digi neo 8 port software version 40002369_E.src.rpm on Red Hat Enterprise 5. I know that this version is not yet supported but I am wondering if there is patch or later version that supports this OS.

Some information about the system that I am trying to do the install on.

uname -a

Linux hostname 2.6.18-8.1.1.el5 SMP

Install errors…

Google finds this…

“devfs has renamed TTY_DRIVER_NO_DEVFS to TTY_DRIVER_DYNAMIC_DEV in tty_driver.h” and " Remove TTY_DONT_FLIP tty flag. This flag was introduced
in 2.1.X kernels to prevent the N_TTY line discipline
functions read_chan() and n_tty_receive_buf() from running
at the same time. 2.2.15 introduced tty->read_lock to protect
access to the N_TTY read buffer, which is the only state
requiring protection between these two functions.

The current TTY_DONT_FLIP implementation is broken
for SMP, and is not universally honored by drivers
that send data directly to the line discipline receive_buf function.

Because TTY_DONT_FLIP is not necessary, is broken in implementation,
and is not universally honored, it is removed. in tty.h"

Taking a look at the source in dgnc_tty.c the hash def
TTY_DRIVER_NO_DEVFS can be renamed but the reference to "
if (test_bit(TTY_DONT_FLIP, &tp->flags))
len = 0;" could cause some issues if its removed.

Has anyone else come across this?

Please give the latest pre-release driver candidate a try with this Distribution version:

Hi all,

I would just like to confirm that using the beta version dgnc-1.3.13.src.rpm has successfully installed and have tested with a serial device. Thanks for the prompt reply userid0 and to the digi support team.
