我需要一些内核模块,这些模块可以在linux源代码中使用,但在Fedora 20上停用,我想知道什么是最容易和最前进的方法来使它们可用. (即然后net / CAN支持导致一些can_ *模块)

我已经遵循了this HowTo(并且还有更多类似的东西)但是“仅构建模块”部分似乎仅适用于尚未禁用的模块,因为在这种情况下甚至缺少模块源.
以下是我按照上述HowTo尝试的内容:
首先,我尝试按照Out Of Tree Modules部分进行 *** 作,但是在内核开发的该死的源代码树中,甚至缺少CAN支持的来源.
所以我尝试从src.rpm构建模块:
$yumdownloader --source kernel$sudo yum-builddep kernel-3.14.8-200.fc20.src.rpm$rpm -Uvh kernel-3.14.8-200.fc20.src.rpm$cd ~/rpmbuild/Specs$rpmbuild -bp --target=$(uname -m) kernel.special$cd ~/rpmbuild/BUILD/<kerneldir>/<linuxdir>$<configure the kernel using menuconfig>$make prepare
然后我建立并得到一些警告:
$make -C /lib/modules/`uname -r`/build M=`pwd`/net/can modulesmake: Entering directory `<rpmbuild-BUILD-kernel-linux-dir>' WARNING: Symbol version dump <rpmbuild-BUILD-kernel-linux-dir>/Module.symvers is missing; modules will have no dependencIEs and modversions.

我刚刚运行make模块时没有收到第一个警告,但这花了我大约一个小时.
但是,安装后,.ko文件位于错误的目录中
(/usr/lib/modules/3.14.8而不是/usr/lib/modules/3.14.8-200.fc20.x86_64)并且在depmod -a和modprobe之后我可以得到
modprobe: ERROR: Could not insert 'can': Exec format error
我究竟做错了什么?
解决方法 我想我得到了它,虽然它可能远非完美.>通过运行准备源代码
rpmbuild -bp --target=$(uname -m) kernel.spec
>转到构建目录,例如:
cd ~/rpmbuild/BUILD/kernel-3.14.fc20/linux-3.14.8-200.fc20.x86_64
>编辑Makefile并将EXTRAVERSION设置为:
EXTRAVERSION = -200.fc20.x86_64
>启用模块.我建议从configs目录下的相应文件开始(我使用了kernel-3.14.8-x86_64.config).
>为模块准备内核:
make modules_prepare
>构建模块:
make M=drivers/net/can
>利润!插入模块:
insmod can-dev.ko总结
