Source code of LDD3 compiled by Fedora14

Go directly to a directory under example, such as scull to make. A bunch of errors will be reported, indicating that the ora14 header file with the kernel source code (or yuminstallkernel-devel to install these header files) without the source code, however, for examples in ldd3 compilation, these header files are sufficient and the Makefile has specified the correct Kernel Directory # KERNELDIR? =/Lib/modules/$ (shelluname-r)/build. Therefore, make directly to a directory under example, such as scull, and a bunch of errors will occur.
Description: The header file of Fedora14 with the kernel source code (or yum install kernel-devel to install these header files) does not contain the source code. However, for examples of compiling ldd3, these header files are sufficient.
And the Makefile has specified the correct kernel directory.
# KERNELDIR? =/Lib/modules/$ (shell uname-r)/build
These errors are only caused by inconsistent kernel versions.
The ldd3 example is from the 2.6.10 kernel era, while the fc14 kernel version is 2.6.35.6-45.
Some data structures updated in the 2.6.35 kernel, so the ldd3 example written with the 2.6.10 kernel at the time is likely to use the new kernel for compilation and sometimes Error
The solution is to allow the ldd example to adapt to the new kernel version or change to the 2.6.10 kernel for compilation.
Error: 'System _ utsname' undeclared
The new version does not have this stuff. Simply define a char * system_utsname = "x86" in that file, and then remove. machine from the code.


If you want to have a complete kernel source code to replace the built-in fc14 shell, you can do the following:
Go to the following link to download the 14 kernel, which is the kernel-2.6.35.6-45.fc14.src.rpm
Http://download.fedora.RedHat.com/pub/fedora/linux/releases/14/Fedora/source/SRPMS/
In addition, 15
Http://download.fedora.redhat.com/pub/fedora/linux/releases/15/Fedora/source/SRPMS/
13 12 11 10 9 and so on
Http://archives.fedoraproject.org/pub/archive/fedora/linux/releases/
For example
Http://archives.fedoraproject.org/pub/archive/fedora/linux/releases/12/Fedora/source/SRPMS/
This is the case now, but we may move to archives in the next 15 days.
Note: You can go to www.kernel.org to download the kernel source code of a certain version. However, after downloading and compiling, You need to replace (install) The fc14 kernel image,
In this way, the kernel module compiled with the kernel source code of this version will pass smoothly in the insmod of the local machine.

Now we have reached a fully compiled kernel source code,
/Lib/modules/2.6.35.6-45. fc14.i686/build/already exists and connects/Usr/src/kernels/2.6.35.6-45. fc14.i686,
Now connect it to/root/rpmbuild/BUILD/kernel-2.6.35.fc14/linux-2.6.35.i686/
(This does not seem to have to be done by yourself. The link will be automatically corrected when make install is executed)

If you want to install the compiled Kernel
Run
Make install
(The System will copy vmlinuz and System. map to the/boot directory and automatically add the $ (uname-r) suffix,
Modify grub/boot/grub/menu. lst at the same time, and manually copy vmlinuz and System. map versions earlier than 2.6)
Restart to see the new kernel.

The file indicated by kernel is a kernel image.

System. map is the symbol table exported by the kernel.
All three files exist under/boot.
