internal modem installation problem on sony vaio
 

Hi,
i have sony vaiio vgn-s4m lap-top with an internal modem V90.
previously i had installed mdk 10.0 on it, and configured/installed this modem using slmodem-2.9.10.tar.gz.
this was working fine.
recently i installed mandriva 2006 [deleting mdk10.0], because i was told that as this is an advanced version, this detects
and installs most of the internal modem.
but it did not happened automatically. so i tried to configure/install it with the same tar ball and it is giving me errors
detailed as follows. please let me know what is this error? and how to correct it?
also i would like to know that if sonething can be easily done in earlier versions why it doesnt happen in so called advanced versions?
thanks,
jayant.

Are your kernel header files installed? They may not be installed by default. It looks like a missing declaration, and I would say that slmodem (being a kernel module) would need to link against the kernel headers.

i have downloaded kernel-source files. but the same problem prevails.
i could not get kernel header files separately. do the kernel source files contain kernel header files?
thanks

On Debian, the kernel headers come in a separate package; you'll have to check your own distribution's policy on that!

I know this post is old news but leaving a solution is not a bad idea.

The problem is how GCC4 handles the static keyword. Open modem/modem.c and go to lines 1701 then 1707 and remove the keyword static.

Afterwards all should compile without any problems. These edits should not affect the applications functionality.
