Has anyone compied the techwell drivers on ubuntu 14.04 lts?

[kingofkya]

I cant seam to get it to work, this driver used to be super simple to compile:(



And its seams the gitorious site is haveing issues not sure if that is still the right place to get the drivers:
gitorious.org/tw68/

Anyway i made a copy In case anyone needs it / the site goes away.
kneale.us/tw68-tw68-v2.tar.gz

I have zero idea but I took a look anyway

a) The code uses __dev* initializers - they are no longer used in later linux kernels

To fix it, add this to tw68.h right at the top

Code: Select all

#define __devinit
#define __devinitdata
#define __devexit
#define __devexitdata
#define __devexit_p

b) Next up, certain structures have changed in newer library versions.
Edit tw68-core.c:line 591, change "parent" to "dev_parent" (that's the new name)

Code: Select all

 vfd->dev_parent  = &dev->pci->dev;

c) Finally, edit tw68-video.c: line 2079
comment out .current_norm --> that field does not exist anymore in V4L

now make and it will compile.

Whether it works or not, I haven't a clue
