Am urmatoarea problema:

La compilarea PWLIB, scriptul configure nu gaseste "videodev2.h" care tine de V4L2... fisierul respectiv chiar nu exista in /usr/include/linux in schimb exista in dir cu sursele kernelului. Am incercat sa-l copiez manual de acolo in directorul necesar... insa fara nici un rezultat.
Chiar daca am dezactivat --disable-v4l2 chiar daca make opt nu-mi da nici o eroare, la sfarsit ma aleg cu libraria respectiva cu "Segmentation fault"... adica inutila.
In acest sens am activat si I2C in kernel in afara de V4L1 si V4L2 deoarece asa scrie in doc.... insa tot fara efect. Dupa compilare si instalarea kernelului, tot nu apare fisierul videodev2.h unde trebuie :(

Cum afiseaza configure:
------------------
checking linux/videodev.h usability... yes
checking linux/videodev.h presence... yes
checking for linux/videodev.h... yes
checking for V4L video support... yes
checking for linux/videodev2.h... no
checking for linux/videodev2.h with sys/types.h... yes
checking for V4L2 video support... yes
-------------------

Ce trebuie sa am activat in kernel pentru a avea fisierul respectiv corect instalat ?

Pointeaza corect spre surse. Symlink-ul build din /lib/modules/kernel_version pointeaza corect catre sursele/headerele kernelului? Fisierul cu pricina exista:
linux-2.6.24.2/include/linux/videodev2.h

Redenumeste /usr/include/linux si apoi symlink /usr/include/linux -> /usr/src/linux-2.6.24.3/include/linux

Cred ca am gasit buba...

Am incercat o versiune mai noua de pwlib (2.02) si vad ca la asta scriptul configure detecteaza corect lipsa videodev2.h
Din pacate tot segmentation fault primesc si la asta...insa oricum asta nu are legatura cu kernel-ul...sau cel putin asa cred.
Oricum nu inteleg de ce dupa compilarea kernelului fisierul videodev2.h nu este instalat :(
