Trouble installing GSM device driver using 'make' on Ubuntu 8.04, 2.6.24-19-lpia
 

Hello,
I am trying to install a device driver for a GSM mobile broadband device on somebody's netbook at work. The device is an AT&T USBconnect Mercury. The netbook is running ubuntu 8.04 with the 2.6.24-19-lpia kernel. I am somewhat decent with linux; I've tried plenty of different distros and I have installed with make a couple of times in the past, but I wouldn't consider myself a super user by any means.

The problem:
From what I have read, the ATT Mercury is the same as the Sierra Wireless Compass 885, so I have been trying to install the Sierra driver since there is apparently no driver from ATT.
I downloaded the driver from http://www.sierrawireless.com/faq/ShowFAQ.aspx?ID=1229 and tried following the instructions:
1) unpack
2) cd to the directory
3) make
4) make install

However, when I run 'make' I get the following:

myra@myra:~/Desktop/v1.3.1b_Kernel2.6.24$ make
make -C /lib/modules/2.6.24-19-lpia/build SUBDIRS=/home/myra/Desktop/v1.3.1b_Kernel2.6.24 modules
make[1]: Entering directory `/lib/modules/2.6.24-19-lpia/build'
make[1]: *** No rule to make target `modules'. Stop.
make[1]: Leaving directory `/lib/modules/2.6.24-19-lpia/build'
make: *** [default] Error 2

I have been looking at a lot of different threads. I made sure to download the source code for my kernel using synaptic, as well as the linux headers. These are the threads I've read:

Any help would be appreciated. Thanks in advance.
