我正在尝试安装Linux外部内核模块。我已经解压缩了完整的源代码tarball：有源代码（.c），Kconfig和Makefile。
在使用make menuconfig向.config添加选项时，我得到了
make：***没有规则来制作目标`menuconfig'。停止。
（我在make menuconfig下尝试了/usr/src/Linux-header-3.xxxx它确实有效;菜单弹出！）
我对这个make menuconfig机制感到有些困惑。我是否必须将我的Kconfig与Linux顶级Makefile（Kconfig？）相关联或添加另一个Kbuild文件？
下面列出了几个文件：
的Kconfig：
config PMFS
tristate "Persistent and Protected PM file system support"
depends on HAS_IOMEM
select CRC16
help
If your system has a block of fast (comparable in access speed to
system memory) and non-volatile byte-addressable memory and you wish to
mount a light-weight, full-featured, and space-efficient filesystem over
it, say Y here, and read <file:Documentation/filesystems/pmfs.txt>.
To compile this as a module, choose M here: the module will be
called pmfs.
config PMFS_XIP
bool "Execute-in-place in PMFS"
depends on PMFS && BLOCK
help
Say Y here to enable XIP feature of PMFS.
config PMFS_WRITE_PROTECT
bool "PMFS write protection"
depends on PMFS && MMU && HAVE_SET_MEMORY_RO
default y
help
Say Y here to enable the write protect feature of PMFS.
config PMFS_TEST
boolean
depends on PMFS
config PMFS_TEST_MODULE
tristate "PMFS Test"
depends on PMFS && PMFS_WRITE_PROTECT && m
select PMFS_TEST
help
Say Y here to build a simple module to test the protection of
PMFS. The module will be called pmfs_test.
生成文件：
obj-$(CONFIG_PMFS) += pmfs.o
obj-$(CONFIG_PMFS_TEST_MODULE) += pmfs_test.o
pmfs-y := bbuild.o balloc.o dir.o file.o inode.o namei.o super.o symlink.o ioctl.o journal.o
pmfs-$(CONFIG_PMFS_WRITE_PROTECT) += wprotect.o
pmfs-$(CONFIG_PMFS_XIP) += xip.o
