\linux-3.0.35 内核编译驱动问题

您这个不带Kconfig和Makefile吗

您这个不带Kconfig和Makefile吗

可以修改 makefile
obj-$(CONFIG_XR17V35_PORT)        += xr17v35x.o

KConfig
config XR17V35_PORT
        tristate "XR17V35"
        default m
        
我用dmesg看了一下， 有这个错误：

xr17v35x: no symbol version for module_layout
xr17v35x: no symbol version for module_layout
xr17v35x: no symbol version for module_layout
mxs_perfmon: no symbol version for module_layout


看来可能还是因为没有编译内核，直接make modules 导致的。这样出来的ko文件信息有问题
，看来要解决内核编译失败那个问题了

这个驱动模块只有一个makefile
Kconfig 不需要的

KERNEL_SRC = /lib/modules/`uname -r`/build

all: build

obj-m += xr17v35x.o

xrpci-objs :=        xr17v35x.o

EXTRA_CFLAGS +=  -DDEBUG=1

build:
        $(MAKE) -C $(KERNEL_SRC) SUBDIRS=$(PWD) modules

install:
        cp xr17v35x.ko /lib/modules/$(shell uname -r)/kernel/drivers/char
clean:
        rm -f *~ *.o
        rm -f *~ *.ko

我配置内核，把网络模块去掉了，又报这个错。。。

这个驱动在内核编译成功之后，可以编译使用了，结贴，不过又出现了新的问题
