Issues installing PCI modem driver

Hi,
Be sure you have installed the package 'build-essential'.

Thanks for your answer, Andrea.

I've cheked synaptic and I don't have the package 'build-essential' installed. Is It necessary?

I tried to install it with my live-cd, but it doesn't work bcause some dependences (I guess) are only available over the internet and I'm not able to surf without this modem I'm trying to configure. If it's necessary, how can I install it? I have my modem working with Windows and I can share my hard disk with Linux (at least NTFS-3g is installed and working :D ) so if I can download the package (perhaps) I can solve my problem.

Can you help me?

Thanks again (Grazie mille)

Emanuele

I think you will need only libc6-dev. Try to install it from your CD or download it from http://packages.ubuntu.com .

Hope this helps.

Thank you again, Andrea.

I tried to install the package from the CD, but I failed. So I've downloaded the .deb package. Now I need to install libc6-dev, how can I do that?

Since I guess that it should be a standard procedure, for me could be ok also just to get a link. I googled a bit, but I didn't find nothing appropriate to my low level linux knowledge. For example: where should I place the .deb file, first of all?

Again I thank you for the very useful support and I wish you a very happy new year!

Emanuele

The procedure is simple: just double click on the deb package and click on "Install package".
You can also use the terminal instead:
cd "/path/to/deb/file"
sudo dpkg -i name_version.deb

Choose the way you prefer! ;)

PS: I suggest you to use http://wiki.ubuntu.com or http://wiki.ubuntu-xx.org (for example http://wiki.ubuntu-it.org for the Italian) for a good documentation.

I've installed the entire 'build-essential' package with its dependences. Unfortunately the problem still remains with the command '$ make'. This is the output:

emanuele@emanuele-desktop:~/Documenti/slmodem-2.9.10$ make

Do I need to install anything else?

Thanks, bye.

Emanuele

Now the problem is changed :)
Try with:
sudo make

Yes, the problem is changed (good new), but still a problem remains (bad new) :)

Too bad, also with 'sudo make', I've got the same answer:

make -C modem all
make[1]: Entering directory `/home/emanuele/Documenti/slmodem-2.9.10/modem'

make: *** [modem] Error 2

Desperately, I tried to run 'sudo make install' after 'sudo make' anyway, but it's useless.

Thanks anyway, Andrea! I hope you can give me another magic solution of yours! :) .

Emanuele

Please, give me the output of:
apt-cache show gcc | grep Version; apt-cache show linux-headers-`uname -r` | grep Version

The outputs are:

emanuele@emanuele-desktop:~/Documenti/slmodem-2.9.10$ apt-cache show gcc | grep Version
Version: 4:4.1.2-9ubuntu2

and

emanuele@emanuele-desktop:~/Documenti/slmodem-2.9.10$ apt-cache show linux-headers-`uname -r` | grep Version
Version: 2.6.22-14.47
Version: 2.6.22-14.46

I'm crossing my fingers.... :D

Emanuele

It seems a problem of the driver code. Can you send it to me by e-mail or do you prefer to use more linux-friendly software?

I'd like to use a more linux-friendly software, but I haven't found nothing appropriate that is different from the file 'slmodem-2.9.10_netodragon.tar.gz' that I'm sending to you by email (thanks again, by the way!). If you can suggest me something, I'll be very happy to give a try to your proposal.

Yesterday night I also found this file: 'slmdm-2.7.10_debug.tar.gz' that might be interesting but has a "suspicious" name (why "debug"?) and seems to be an older version of the driver. Anyway remember that I'm a newbie so, if you think that could be useful, I'll give it try or I'll send it to you by email.

Thank you!

Emanuele

PS: sorry, I'm very ashamed, but I don't know how to retrieve you email address (my attempts failed miserably). Can you explain me how can I send the file to you by email?

[OT] My real wish is to use more linux-friendly HARDWARE! :D
Unfortunately I bought this softmodem some years ago, when I didn't know of linux existence (and compatibility issues) :( [/OT]

Sorry, I thought about this just now: do I need to send the file by email to the 'question21108 at answers.launchpad.net' address?

Emanuele

No, to 'andrea-bs at ubuntu.com', thanks.

Some minutes ago I sent the file. Let me know if you had problems with the email or you need other files.

Emanuele

Hello,

first of all a loud THANK YOU to Andrea: the problem still exists but I'm one step forward. In other words: the command 'make' now works (just with a few warnings),

but when I run 'sudo make install' (as suggested in the README file) again an error comes out:

As usual, I don't know why this happens. Sorry, I still need help :(

Emanuele

The file 'slmodem-2.9.10/drivers/kernel-ver.c' must be modified at line 7 to solve the problem with 'sudo make install'. I substituted

#include <linux/version.h>

with

#include <linux/utsrelease.h>.

This is necessary because has been moved a file in the Linux source code (thanks again to Andrea Corbellini for the solution and the explanation).

Bad luck still hangs on me, in fact after the corrections, I've got:

What's the problem now?

Thanks, bye.

I see there are other files moved. I'll look for them this evening :)

I saw there are too many files and option changed and patch them may take a lot of time.
I suggest you to use the old kernel headers. You can find them at this link: http://packages.ubuntu.com/cgi-bin/search_packages.pl?keywords=linux-headers&searchon=names&subword=1&version=dapper&release=all
Use the oldest version (the first) for your architecture. If you are unsure on what arch are you using, type `uname -m` in a terminal.
Remember to change the headers directory in the modem files!

If you are unsure, just ask :)

Be patient, please: just a couple of questions.

1.
Do I need to uninstall the 'linux-headers-2.6.22-14-generic' before to install the 'linux-headers-2.6.15-23-686_2.6.15-23.39_i386.deb' package or can I install the two versions of the headers side by side?

2.
Surely I have to modify 'slmodem-2.9.10/drivers/kernel-ver.c' at line 7 to restore the previous version of the file and I need to run '$ make KERNEL_DIR=/etc/src/linux-headers-2.6.15-23...', but do I need also to restore the old, NOT modified 'modem.c' file?

Thank you, bye.

Emanuele

> Be patient, please: just a couple of questions.
No problem. I'm here just to answer users questions :)

1.
> Do I need to uninstall the 'linux-headers-2.6.22-14-generic' before to install the 'linux-headers-2.6.15-23-686_2.6.15-23.39_i386.deb' package or can I
> install the two versions of the headers side by side?
No, you don't need to uninstall the newer package.

2.
> Surely I have to modify 'slmodem-2.9.10/drivers/kernel-ver.c' at line 7 to restore the previous version of the file and I need to run '$ make KERNEL_DIR=/et
> /src/linux-headers-2.6.15-23...', but do I need also to restore the old, NOT modified 'modem.c' file?
Yes, you need.

Unfortunately, when I double-click on the 'linux-headers-2.6.15-23-686_2.6.15-23.39_i386.deb' icon, I can't install the package because I have a red text saying 'Error: Dependency is not satisfiable: linux-headers-2.6.15-23'. How can I install the package?

Just to be sure: is it right to download the 'linux-headers-2.6.15-23-686_2.6.15-23.39_i386.deb' package if I have an Intel Pentium 4 2.8 GHz CPU? Anyway, I've got this:

emanuele@emanuele-desktop:~$ uname -m
i686

Thank you.

Emanuele

Tonight I got and ran the 'scanModem' utility. Perhaps it could be the solution to my problems! It has detected my softmodem and said

The modem is supported by the Smartlink slamr driver

with a lot of informations.

Now I'm struggled by the choice between the two paths that I can walk: should I continue trying to compile this old 'slmodem-2.9.10_netodragon.tar.gz' driver, or it would be better to follow the instructions given at this url: http://wiki.ubuntu-it.org/Hardware/Modem/Dialup/Smartlink ?

Any suggestion is well appreciated! Potentially I'm able to upload my 'Modem' folder (just 86 KB) that contains a lot of information about my modem and my workstation in general.

Again, thank you.

Emanuele

I think it's better following the wiki, but I'm not 100% sure it will work as I said in the mail.
However, if it has detected your modem, you have more chances so why don't try to follow the wiki? :)

I'll follow the wiki.

For now, I keep on stand by this question and if I'll experience success, I'll close the question. Otherwise I'll follow this 'Launchpad path'. So, for now, many many thanks to Andrea for the time and the patience in answering my questions!

Emanuele

I can't believe that installing whatever is necessary to make a 56K modem work is this involved. I also can't believe that an OS as well thought out as Ubuntu doesn't have what it takes to make a 56K modem work.

Congratulations to Andrea for all of the effort put into trying to explain. Prsonally, as a newbie, I'm just as lost as Emanuele.

     Ed

Ed,

if you have my same softmodem (Netodragon MDV92XP) I'd like to share our experience about it.

I followed the wiki to install its drivers and all seemed fine. Unfortunately, the modem can't ''catch'' the server answer and I've done a lot of tests with different Init strings, but it doesn't work.

You can find more details at this url: https://answers.launchpad.net/ubuntu/+question/22086 .

Let me know if you have the same problem or not. Bye.

Emanuele

Got your question, Emanuele,
Because I signed up to be notified of additions to the question and it
was relayed to me.

I do not have a Netogragon modem, but a PCI Soft Modem. After
spending about eight hours over a number of days and finding no
solution, I have decided to give up. I just can't understand why
Ubuntu programmers didn't allow for 56K modems, but have programmed for
broadband stuff. Are there really that many people with broadband?

Certainly hope you find a solution.
