dgnc module compiling on recent kernel

ybonnamy · March 12, 2010, 2:21pm

Hi, i’d like to compile the dgnc driver with a recent kernel :

2.6.31-gentoo-r6

i already patched a few things :

has anybody here already gone though porting this driver on recent kernel ?

Thanks for your help.

Have you tried the latest driver candidate?

ftp://ftp1.digi.com/support/beta/linux/dgnc/dgnc-1.3-18.src.rpm

ybonnamy · March 12, 2010, 3:48pm

it works, thanks a lot, sorry for not finding this by myself

Please confirm you are using the latest driver candidate from:

ftp://ftp1.digi.com/support/beta/linux/dgnc

There have been recent changes to accommodate newer kernels.

ybonnamy · April 13, 2010, 7:21am

my previous post was with dgnc-1.3-18.src.rpm dated from “Oct 22”, i’ve just retried with the dgnc-1.3-18.src.rpm dated from “Apr 12” and result is the same.

We’ll need to see a complete log of the driver compilation starting with ./configure.

Looks like this distro broke where some of the defines are supposed to be.

Please run the following to tell us where the Gentoo distro put them:

grep TASK_INTERRUPTIBLE /usr/src/linux-2.6.32-gentoo-r7/include/linux/*

grep schedule_timeout /usr/src/linux-2.6.32-gentoo-r7/include/linux/*

grep signal_pending /usr/src/linux-2.6.32-gentoo-r7/include/linux/*

i’m really surprised, linux-2.6.32-gentoo-r7 is just supposed to be a vanilla kernel plus some gentoo patches. the compilation was successful on linux-2.6.31-gentoo-r6 and the 3 grep you asked for returns the same results for both kernel :

# grep -l TASK_INTERRUPTIBLE /usr/src/linux-2.6.32-gentoo-r7/include/linux/*

did you successfully compiled dgnc against the 2.6.32 kernel ?

ok, sorry for being lazy, i have googled a bit since, and found that :

> Can insert #include into drivers/char/rtc.c fix this?

and yes, it fixes it , here is the patch :
