使用make在linux上编译驱动程序

这个错误信息是什么意思？ 我正在尝试运行make。 看起来缺少配置。 配置是内核源的一部分？

make -C /lib/modules/4.2.0-19-generic/build SUBDIRS=/home/glochild/Downloads/AX88179_178A_LINUX_DRIVER_v1.10.0_SOURCE modules make[1]: Entering directory '/usr/src/linux-headers-4.2.0-19-generic' CC [M] /home/glochild/Downloads/AX88179_178A_LINUX_DRIVER_v1.10.0_SOURCE/ax88179_178a.o /home/glochild/Downloads/AX88179_178A_LINUX_DRIVER_v1.10.0_SOURCE/ax88179_178a.c:55:6: error: macro "__TIME__" might prevent reproducible builds [-Werror=date-time] " " __TIME__ " " __DATE__ "\n" ^ /home/glochild/Downloads/AX88179_178A_LINUX_DRIVER_v1.10.0_SOURCE/ax88179_178a.c:55:19: error: macro "__DATE__" might prevent reproducible builds [-Werror=date-time] " " __TIME__ " " __DATE__ "\n" ^ cc1: some warnings being treated as errors scripts/Makefile.build:264: recipe for target '/home/glochild/Downloads/AX88179_178A_LINUX_DRIVER_v1.10.0_SOURCE/ax88179_178a.o' failed make[2]: *** [/home/glochild/Downloads/AX88179_178A_LINUX_DRIVER_v1.10.0_SOURCE/ax88179_178a.o] Error 1 Makefile:1398: recipe for target '_module_/home/glochild/Downloads/AX88179_178A_LINUX_DRIVER_v1.10.0_SOURCE' failed make[1]: *** [_module_/home/glochild/Downloads/AX88179_178A_LINUX_DRIVER_v1.10.0_SOURCE] Error 2 make[1]: Leaving directory '/usr/src/linux-headers-4.2.0-19-generic' Makefile:30: recipe for target 'default' failed make: *** [default] Error 2 

Answer 1

在Makefile中将其添加到CFLAGS变量中

 -Wno-date-time 

这将禁用警告，因为警告被视为错误，因为Makefile传递-Werror与CFLAGS代码无法编译。

Answer 2

我理解这是由于警告被添加到GCC的更高版本，最初将使用例如-Wall进行编译，但由于此额外限制现在不再这样做了。

如果你不能使用上面的makefile mod修复它，我已经在我自己的驱动程序版本中修复了它，只包括源的有问题的行：

 #pragma GCC diagnostic push #pragma GCC diagnostic ignored "-Wdate-time" ... code with __DATE_ __TIME__ #pragma GCC diagnostic pop 

它仅为受影响的线路关闭“新”诊断。
