3 years ago Same issue: File 'usb-vhci-hcd.c' : replace 'show_debug_output' by 'debug_output_show' replace 'store_debug_output' by 'debug_output_store' replace 'static DRIVER_ATTR(debug_output, S_IRUSR | S_IWUSR, show_debug_output, store_debug_output);' by 'static DRIVER_ATTR_RW(debug_output);'
Do the same for file 'usb-vhci-iocifc.c' & add the following header
Hi,
I've downloaded the code from vhci_hcd and tried to build it, but get the following errors:
