I need a dial-up data/fax modem and have obtained a Pluscom USB2.0 Fax Modem which works well under Windows. However I need to use it with Ubuntu, one needs first to download the required Linux driver. This I have done successfully and unpacked the deb package. However when I try to install it it is unsuccessful and the following message is received:




gerald@gerald-laptop:~$ sudo dpkg -i dgcmodem_1.01_i386.deb
[sudo] password for gerald:

If you need assistance or more information, please go to:

When reporting a problem for the first time, please send
us the file generated by "dgcconfig --dumpdiag".


No pre-built modules for: Ubuntu-9.10 linux-2.6.31-19-generic i686-SMP


Trying to automatically build the driver modules...
(this requires a C compiler and proper kernel sources to be installed)


Where is the linux source build directory that matches your running kernel?
[/lib/modules/2.6.31-19-generic/build]


WARNING: missing file dgcconfig --dumpdiag/include/linux/autoconf.h
The cause of this is usually a missing or unconfigured
kernel source tree (and sometimes an incorrect directory or symbolic link).


First, ensure that the proper kernel source and compiler packages
from your distribution vendor and/or the community are installed.


The Linux kernel can then be reconfigured by running "make menuconfig"
under the kernel source directory (usually /usr/src/linux).


Verify that the proper options for your system are selected.


Then compile and install your new kernel (for more information about
this procedure, see the README file under the kernel source directory),
reboot the system using the new kernel, and re-run "dgcconfig".


I am a newcomer to Ubuntu and would much appreciate some help please. I have not contacted Linuxant yet as I feel that the first problem is my lack of knowledge of Linux not the driver.

It looks like you need to install build-essentials. Search for it in either the Software Center or Synaptic Package Manager.

Thank you for your reply Cariboo907.
As I said, I have just come to Ubuntu and though what you say I am sure makes sense I need a further explanation please. I have tried to find something as you suggested concerning "build essentials" but with no success, what exactly are the files I need to find?

When trying to automatically build the driver modules where do I find a C compiler and the proper kernel sources to be installed, what exactly is the kernel source? I have just updated the previous kernel through update manager.

What is the linux source build directory that matches my running kernel?
