Assume /usr/src/linux-1.2.3
/usr/src/linux-4.5.6
If I want to compile linux-4.5.6, I remove any symbolic link called:
/usr/src/linux (rm /usr/src/linux)
Then I create a symbolic link:
ln -s /usr/src/linux-4.5.6 /usr/src/linux
If I want to compile linux-2.3.6, I remove any symboloc link called:
/usr/src/linux (rm /usr/src/linux)
Then I create a symbolic link:
ln -s /usr/src/linux-1.2.3 /usr/src/linux
Header files that refer to the kernel (in /usr/include) are supposed
to be symbolic links through /usr/src/linux so they never have to be
changed. There are two of them:
/usr/include/linux
/usr/include/asm
They should have been created as:
ln -s /usr/src/linux/include/asm /usr/include/asm
ln -s /usr/src/linux/include/linux /usr/include/linux
Once these are set properly, they never have to be changed. The
kernel, itself, will compile without setting any links at all.
However, many system utilities like "mount", depend on kernel
headers so they won't compile if the links haven't been set properly.
When you untar a new tarball for the kernel source, this makes a
directory called "linux". Therefore you do not want to untar it
into /usr/src. Instead, if /tmp is on the same file-system as /usr/src,
you can do:
cd /tmp
tar -xzf ~/linux-1.2.3.tar.gz
mv linux /usr/src/linux-1.2.3
Otherwise, untar it into some dummy directory:
mkdir /usr/src/foo
cd /usr/src/foo
tar -xzf ~/linux-1.2.3.tar.gz
mv linux ../linux-1.2.3
cd ..
rmdir foo
Note: None of this syntax has been checked. Don't blindly follow it.
Follow the logic instead.
Cheers,
Dick Johnson
