Missing header file compiling PEAK Linux driver 8.1

[skllrn]

Hi,
I am having an issue comiling the PEAK Linux driver 8.1 with CAN FD support.
The device I want the driver to run on is a armv7 (beaglebone) with newest debian jessie image.

Thus I followed the documentation and installed the necessary packages (kernel headers, libpopt-dev),
I get the warning that some functions are declared implicit.
Those warnings are treated as errors and compilation stops.

Do I have to change some settings to ignore those warnings because maybe the header (/linux/pci.h) gets included afterwards or am I missing something else here?


Thats the output make gives me in ~/peak-linux-driver-8.1/driver:

Code: Select all

Hi,

Function "pci_enable_msi_range()" is always present in mainline Kernel 4.x.
I suppose that CONFIG_PCI isnot defined in your specific one...

Could you please check this?

Code: Select all

$ grep CONFIG_PCI= /boot/config-`uname -r`

Which kind of PEAK-System hardware do you want to use? If it's not a PCI one, try to compile the driver without any PCI support, like this:

Code: Select all

$ make PCI=NO_PCI_SUPPORT

Stéphane

First of all thank you for your help and time Stéphane.

You are right, the PCI_CONFIG flasgs are indeed not set.
I am using an PCAN-USB FD adapter, so to exclude the PCI support solves my problem.
