Postup zprovoznění pod Linuxem

Ovladač je značně zastaralý a nelze zkompilovat na jádrech 3.5 a vyšší. Povedlo se mi napsat patch pro zprovoznění na Linux Mint 17 resp. Ubuntu 14.04 s jádrem 3.13. Nezkoušel jsem dálkový ovladač, proto uvádím částečná podpora.

1. Nainstalujte zdrojové a hlavičkové soubory jádra:

   sudo apt-get install linux-source
   sudo apt-get install linux-headers-`uname -r`
   

2. Zdrojové soubory rozbalte

   cd /usr/src
   tar -xjvf linux-source-XYZ

3. Vytvořte symbolický odkaz v /lib/modules/jádro/source na zdrojové soubory jádra

   ln -s /usr/src/linux-source-XYZ /lib/modules/`uname -r`/source

4. Ze stránek výrobce si stáhněte originální ovladač zde a rozbalte do adresáře /usr/local/src/a867_drv_v1.0.29
5. Vytvořte patch soubor a867_v1.0.29.patch a uložte do adresáře a867_drv_v1.0.29

   Aplikujte patch

   patch -p1 -i a867_v1.0.29.patch

6. Kompilace a instalace ovladače

   make
   make install 
   

7. Pokud vše proběhlo jak má, vytvořil se soubor a867.ko, který se zkopíroval do adresáře /lib/modules/j`uname -r`/kernel/drivers/media/usb/dvb-usb
   Po instalaci doporučuji aktualizovat informace o modulech

   depmod -a

Poznámka

a867_v1.0.29.patch

Při kopírování patche z WEBu je problém, že většina řádků je zakončena CRLF znaky. Tento detail, ale způsobí, že patch nejde aplikovat. Dneska jsem ještě objevil mušku - na uložto už jsem novou verzi nedával. Jedná se o Makefile řádek ifneq (,$(wildcard $(KSRC)/drivers/media/dvb/.))^M. Správně je ifNeq.
