推荐答案

我不确定您遇到什么问题，但是我可以在Ubuntu 18.04下编译并安装驱动程序.我在编译过程中确实遇到了一些错误，并按照以下步骤进行了修复:

I am not sure what problems you are having, but I could compile and install the driver under Ubuntu 18.04. I did get a few errors during compilation, which I fixed as follows:

错误1:

/opt/DigitalPersona/urusdk-linux/Linux/drivers/source/usbdpfp/usbdpfp.h:186:5: 错误:类型名称未知的"wait_queue_t" /opt/DigitalPersona/urusdk-linux/Linux/drivers/source/usbdpfp/usbdpfp.c:606:9: 错误:函数"copy_from_user"的隐式声明；你的意思 ‘raw_copy_from_user’? [-Werror =隐式函数声明] ---以及一系列相关的编译错误---

/opt/DigitalPersona/urusdk-linux/Linux/drivers/source/usbdpfp/usbdpfp.h:186:5: error: unknown type name ‘wait_queue_t’ /opt/DigitalPersona/urusdk-linux/Linux/drivers/source/usbdpfp/usbdpfp.c:606:9: error: implicit declaration of function ‘copy_from_user’; did you mean ‘raw_copy_from_user’? [-Werror=implicit-function-declaration] --- and a bunch of related compilation errors---

解决方案: 在/opt/DigitalPersona/urusdk-linux/Linux/drivers/source/usbdpfp/usbdpfp.h中，替换

Solution: In /opt/DigitalPersona/urusdk-linux/Linux/drivers/source/usbdpfp/usbdpfp.h, replace

wait_queue_t                    wait;

使用

wait_queue_entry_t                    wait;

错误2:

opt/DigitalPersona/urusdk-linux/Linux/drivers/source/usbdpfp/usbdpfp.c:2186:22: 错误:函数"signal_pending"的隐式声明；你的意思 "timer_pending"? [-Werror =隐式函数声明]

opt/DigitalPersona/urusdk-linux/Linux/drivers/source/usbdpfp/usbdpfp.c:2186:22: error: implicit declaration of function ‘signal_pending’; did you mean ‘timer_pending’? [-Werror=implicit-function-declaration]

解决方案:

a)在/opt/DigitalPersona/urusdk-linux/Linux/drivers/source/usbdpfp/usbdpfp.h中，替换:

a) In /opt/DigitalPersona/urusdk-linux/Linux/drivers/source/usbdpfp/usbdpfp.h, replace:

 #include <linux/sched.h>

使用

#include <linux/sched/signal.h>

b)在/opt/DigitalPersona/urusdk-linux/Linux/drivers/source/usbdpfp/usbdpfp.c中，替换:

b) In /opt/DigitalPersona/urusdk-linux/Linux/drivers/source/usbdpfp/usbdpfp.c, replace:

#include <asm/uaccess.h>

使用

 #include <linux/uaccess.h>

现在编译并安装模块:

 $ /opt/DigitalPersona/urusdk-linux/redist/usbdpfp start

$ lsmod |grep dpfp
mod_usbdpfp            45056  0
usbcore               286720  7 mod_usbdpfp,usbhid,usb_storage,ehci_hcd,btusb,uas,ehci_pci

祝你好运.
