未指定内核文件 KEXT MAC 环境中出现错误

发布于 2024-12-11 11:56:21 字数 3431 浏览 4 评论 0原文

我尝试为 USBHID 设备实现 KEXT。如果我在终端上检查它能够加载 KEXT ie
Newtok:桌面 Rasheed$ kextutil -nt SampleKextDriver.kext 未指定内核文件;使用正在运行的内核进行链接。 SampleKextDriver.kext 似乎是可加载的(包括磁盘上库的链接)。
但不幸的是我收到了上述消息。我的 plist 文件是

我不知道我哪里错了,我在 Mac OS X 开发方面没有太多经验。任何人都可以建议最好的文件或一些想法

感谢您的信息...

I try implement KEXT for USBHID Device. If i am checking on Terminal It able to load KEXT ie
Newtok:Desktop Rasheed$ kextutil -nt SampleKextDriver.kext
No kernel file specified; using running kernel for linking.
SampleKextDriver.kext appears to be loadable (including linkage for on-disk libraries).
But Unfortunately I Got the above Message. My plist File is

1.加载 kext 时不应使用 -n 选项。
kextutil 的 -n 选项似乎仅用于生成符号文件。
kextutil 的 -t 选项在发生错误时打印失败原因。

有关kextutil的更多详细信息,您应该在终端中输入man kextutil

2.我建议您打开终端并输入以下命令来确定您的驱动程序所依赖的Kexts的版本。 (当然,您应该指定您的驱动程序需要支持的最低系统版本。)

kextstat |grep com.apple.iokit.IOHIDFamily
kextstat |grep com.apple.kpi.iokit
kextstat |grep com.apple.kpi.libkern

然后更新驱动程序 info.plist 的 OSBundleLibraries 字典。

3.希望这对你有用。祝你有美好的一天!

1.U should not using -n option when loading your kext.
The -n option for kextutil seems used to generate the symbol file only.
The -t option for kextutil print the failed reason when error occurs.
For more details about kextutil, u should type man kextutil in the Terminal.

2.I suggest u to open the Terminal and type follow commands to determine the version of the Kexts your driver depends on. (Of course, u should specify the lowest version of the system your driver needs to support.)

kextstat |grep com.apple.iokit.IOHIDFamily
kextstat |grep com.apple.kpi.iokit
kextstat |grep com.apple.kpi.libkern

then update the OSBundleLibraries dictionary of your driver's info.plist.

3.Hope this is useful for u. Have a good day!
