Hi,
I’m trying to install DIGI Neo (dgnc driver) on RedHat EL 3-6
On mode mono processor it’s OK (Kernel 2.4.21-37.EL)
On mode 2 processor (IT’s a Intel core 2 duo processor) the command “insmod dgnc” fail with many unresolved symbols and a mismatch kernel. (Kernel 2.4.21-37.ELsmp)
Why ?
What is the solution ?
Thanks.
Without more detail of the errors, I can only guess that the matching kernel source package is not installed on this host (kernel-devel-2.4.21-37).
Hi,
1)Is it possible to obtain a digi rpm distribution for use neo on kernel 2.4.21-37.ELsmp or it’s necessary to recompile driver for source rpm ?
2)Trace of the insmod command:

Binary RPM images are not available (there are simply too many kernel versions/architectures out there). The driver needs to be compiled against the running kernel.
In your case, it looks like you are running the “SMP” kernel:
>>/lib/modules/2.4.21-37.ELsmp/misc/dgnc.o was compiled for kernel version 2.4.21-37.EL
while this kernel is version 2.4.21-37.ELsmp
A “uname -a” will show the running kernel. For the SMP kernel, you will want to install the “kernel-smp-devel-2.4.21-37” kernel source package instead.
Before installing and compiling driver in smp mode , i try to compile it in normal mode.
So, I install the package “kernel-devel-2.4.21-37”
I Install your package and I pass the commands:
./configure
make ALL
After numberous warning an error occurs :
dgnc_tty.c: Dans la fonction « dgnc_tty_close »:
dgnc_tty.c:2079: opérandes invalides pour le binaire ==
make[1]: *** [dgnc_tty.o] Erreur 1
Attah file is the compilation result.
Thanks.
The errors suggest the “smp” version of the kernel source is not installed. Try installing “kernel-smp-devel-2.4.21-37” package to match your running kernel.
Also, if you are running a Red Hat distribution, you will want to add the “DISTRO” flag when installing. An example for Red Hat ES 3:
./configure --with-DISTRO=REDHAT_ES_3
The RPM syntax:
rpmbuild --rebuild --define DISTRO=REDHAT_ES_3
1)In my precedent post I write that I try to compile in a normal system. So not in smp.
We install kernel-source package
In Red Hat EL3 ther is no kernel-devel nor kernel-smp-devel package
With the command
./configure --with-DISTRO=REDHAT_ES_3
it’s work on a normal kernel (normal compilation)
and it’s work also on a smp kernel (normal compilation and simple tests)
Thank’s a lot.
