------- Comment #3 From Markus Rathgeb 2008-04-22 18:11:26 0000 ------- 
Why emerge prepare to link slusb.o although I use "-usb" as package USE-Flag?


walkuer ~ # grep slmodem /etc/portage/package.use 
net-dialup/slmodem -usb

walkuer ~ # rm /usr/portage/distfiles/slmodem*
/usr/portage/distfiles/ungrab-winmodem*

walkuer ~ # emerge -v slmodem

These are the packages that would be merged, in order:

Same here: usb use flag is removed.

Happens with both slmodem-2.9.11_pre20080126-r1 and slmodem-2.9.11_pre20080401

Nice solution, but I use usb modem :(

I just got bitten by this. I wonder whose idea this retarded source code
self-enforcement is.

Never mind the fact that I'm not actually violating the GPL when I build this
module, only if I actually redistribute it. Hell, I could patch half of Windows
into the kernel, compile the resulting source, print it on a t-shirt, make it
do handstands and still obide by the GPL since I'm not distributing it.
slmodem doesn't vioate the GPL either since it includes no non-GPL code.

I'm pissed, I'm gonna go bitch about this on lkml, someone find a way to fix
this without actually patching the kernel sources..

Please test slmodem-2.9.11_pre20080417 and post here the results.

slmodem-2.9.11_pre20080417 does not work.
Building with -usb and getting the same gpl error.

ebuild hack

ebuild hack (if kernel version is >= 2.6.25, then USE=-usb and apply a patch so
that usb modules are not compiled

dirty patch that avoids compiling usb modules.

(From update of attachment 156327 [details])
ebuild hack (if kernel version is >= 2.6.25, then USE=-usb and apply a patch so
that usb modules are not compiled. also copy the patch file below to files/
folder.

Fixed net-dialup/slmodem-2.9.11_pre20080417, without revision bump.

I preferred to do a quick hack and replace $(obj-m) with whatever modules I
want to install (both of them can be disabled).
