About using the kernel's sources as libs

[fantasmaazul]

I need the the file string.h to compile something and the system cannot find it.
using find:

Code: Select all

# find / -name string.h
/usr/src/kbuild-6.1.106/arch/x86/include/asm/string.h
/usr/src/kbuild-6.1.106/include/asm-generic/string.h
/usr/src/kbuild-6.1.106/include/linux/string.h
/usr/src/kbuild-6.1.106/include/uapi/linux/string.h
/usr/src/kbuild-6.1.106/tools/include/linux/string.h
/usr/src/kbuild-6.1.106/tools/include/nolibc/string.h
/initrd/pup_k/usr/src/kbuild-6.1.106/arch/x86/include/asm/string.h
/initrd/pup_k/usr/src/kbuild-6.1.106/include/asm-generic/string.h
/initrd/pup_k/usr/src/kbuild-6.1.106/include/linux/string.h
/initrd/pup_k/usr/src/kbuild-6.1.106/include/uapi/linux/string.h
/initrd/pup_k/usr/src/kbuild-6.1.106/tools/include/linux/string.h
/initrd/pup_k/usr/src/kbuild-6.1.106/tools/include/nolibc/string.h

I think those are the kernel souces...
Can i use them? i should add them to PATH?

i almost destroyed the system trying another thing. Good thing this is puppy. I rebooted with no consequences.

i tried again and now is there!

Code: Select all

# find / -name string.h
/usr/include/string.h

i guess I re-installed the devx package, probably was that
bye bye!

@fantasmaazul Welcome! - for most puppies, you need to install devx & sources to compile drivers. In aufs, this is done on the fly (loaded in a running system). In overlayfs, devx will load on boot if placed in same folder as puppy sfs, but sources need to be either loaded on boot (first renamed as ydrv or bdrv in modern pups) or in in some pups can be loaded on the fly.
