To build an out-of-kernel module, you must have the kernel headers installed. You are missing those headers.

skambc commented 9 years ago

I have installled the kernel headers.Wher I query the kernel-header use rpm -qa|grep kernel-headers ,it shows "kernel-headers-3.18.3-201.fc21.x86_64" And I installed it again,but it not work yet.

sudo yum install kernel-headers [sudo] password for liu: Loaded plugins: langpacks fedora/21/x86_64/metalink | 7.0 kB 00:00

Package kernel-headers-3.18.3-201.fc21.x86_64 already installed and latest version Nothing to do

Is the kernel-headers not right?

lwfinger commented 9 years ago

There must be a link at /lib/modules/3.17.4-301.fc21.x86_64/build that points to the location of the "include" directory that contains the headers. The error message says that that link is not correctly setup. As I do not use Fedora, I have no idea what you need to do. Check on the Fedora Forums.

@skambc you need to install kernel-devel package too.

I have same issue with build on Fedora 21, and it solve it, because before install kernel-devel /lib/modules/$(uname -r)/build symbolic links target (build -> /usr/src/kernels/$(uname -r)) isn't exists.

@unclechu I am facing the same issue, and I have installed both kernel-devel & kernel- header, but still the problem persists.

[nitin@localhost rtl8188eu]$ sudo make all make ARCH=x86_64 CROSS_COMPILE= -C /lib/modules/3.17.4-301.fc21.x86_64/build M=/home/nitin/rtl8188eu modules make[1]: * /lib/modules/3.17.4-301.fc21.x86_64/build: No such file or directory. Stop. Makefile:147: recipe for target 'modules' failed make: * [modules] Error 2

Is something else the problem?

unclechu commented 9 years ago

@Sekhar-jami may be u installed kernel-devel package of other kernel version, please, show your uname -a and ls -la /lib/modules/.

And see this:

$ yum provides /lib/modules/3.17.4-301.fc21.x86_64/build
Загружены модули: langpacks
kernel-core-3.17.4-301.fc21.x86_64 : The Linux kernel
Источник: fedora
Совпадения с:
Имя файла   : /lib/modules/3.17.4-301.fc21.x86_64/build

kernel-core package provides this directory.

Problem that happened with me, the soft link /lib/modules/<>/build was broken. When I did install headers, it appears to have installed the header for kernel version: 4.8.15-300.fc25.x86_64, whereas my uname -a shows me, that OS is using this kernel: 4.8.6-300.fc25.x86_64.

For the time being, I removed the build link, and recreated it manually. So make all succeeded.

I am on Fedora 25.

lwfinger commented 7 years ago

That is either a Fedora problem, or there were missing packages needed to build out-of-kernel modules. In either case, the link at /lib/modules/uname -r/build should point to the headers for the kernel actually being run. There should be one entry for 4.8.6 and a different one for 4.8.15.
