Im trying to build Klips capable version of OpenSwan using this guide, where it goes something like
make KERNELSRC=/lib/modules/`uname -r`/build module
it gives the fol output
KLIPS26 module built successfully.
ipsec.ko is in /home/naruto/Downloads/Openswan-master/modobj26
-rw-r--r-- 1 root root 11662573 Feb 20 10:32 ipsec.ko
text data bss dec hex filename
367195 15808 8244 391247 5f84f ipsec.ko
use make minstall as root to install it
but when i run
make KERNELSRC=/lib/modules/`uname -r`/build install minstall
it gives me
make[3]:/usr/src/kernels/2.6.32-504.8.1.el6.x86_64/Documentation/DocBook/Makefile:No such file or directory

i do have a dir /usr/src/kernels/2.6.32-504.8.1.el6.x86_64
but /usr/src/kernels/2.6.32-504.8.1.el6.x86_64/Documentation/DocBook does not exist
How can i build ipsec.ko into the kernel, plz guide
Regards
Both kernel looks different to me. one is 2.6.18 other is 2.6.32 and you might also need kernel-devel

I'm trying to make a profile in Volatility 2. I tried on Debian, Kali and Ubuntu 120.04 and Ubuntu 18 (gcc 7.5.0). I tried to update the headers, export pathes etc.. but still I have the same error . I tried also to dowload a profile from github but they are too old ( i didn't found nothing new - just Ubuntu 14) . I also checked module.h info but didn't find antything helpfull. Any idea what i can do?

GOAL: compile samples/bpf, compile bpf/bpftool and use them.
PROBLEM: on a VM with Ubuntu 18.04 bionic with a kernel 4.18.0-25-generic I've installed kernel src code executing apt install linux-source-4.18.0.
Now I cd into /usr/src/linux-source-4.18.0/linux-source-4.18.0/samples/bpf and I run make and the result is
make -C ../../ /usr/src/linux-source-4.18.0/linux-source-4.18.0/samples/bpf/ BPF_SAMPLES_PATH=/usr/src/linux-source-4.18.0/linux-source-4.18.0/samples/bpf

QUESTIONS: what am I missing? After I compile them if I want to write a program which, for example, needs to use bpftool I have to write the program inside the source kernel directory or I can write it everywhere?
Build errors
The first case (Makefile:562: recipe for target 'syncconfig' failed) fails because you run make from the top of the linux kernel repository, and before trying to compile the samples, the build system tries to load a config file to use for your system (but does not find one).
Before trying to build the samples (make -C samples/bpf), you can create a .config file from your current kernel configuration like this:
$ cp /usr/src/linux-headers-$(uname -r)/.config <path to repo>/.config
$ make olddefconfig
Or even simply generate a default config file from scratch:
$ make defconfig
See make help from top directory to see the available make options.
Your second error, regarding bfd.h not found, is that you miss a library. Libbfd on Ubuntu comes with binutils-dev, so apt install binutils-dev should do the trick.
Compiling the programs
Finally, regarding your question on compiling the programs:
You can write and build program from the kernel repository, just by creating a new sample and reusing the existing Makefiles.
You can also write and compile programs outside of the kernel tree. The basic clang (v4.0 or above, if possible v6.0 or above) command to compile them usually looks something like this:
$ clang -O2 -emit-llvm -c my_bpf_prog.c -o - | \
llc -march=bpf -filetype=obj -o my_bpf_prog.o
You can find examples of programs compiled out of the kernel tree in that repository (disclaimer: by my company) or in the XDP tutorial repo.
I have been trying for hours to recompile Linux kernel of https://github.com/torvalds/linux from my MacBook Pro and at the end, still stuck. Hard to find a tutorial to understand how to recompile it, headers missing, bla bla bla.

PS: I tried first adding a syscall website because that's what I'm trying to do at first.
At the begining, I got a .config not found.
*** Configuration file ".config" not found!

*** "make menuconfig" or "make xconfig").

make[2]: *** [silentoldconfig] Error 2
make[1]: *** No rule to make target `include/config/auto.conf', needed by`include/config/kernel.release'. Stop.
Unlike in some web-links, the conf used doesn't exist or something else is wrong, so I'm creating a new .config from "make menuconfig" (as some answers on the web).
Then, I try to compile again. There is some command I tried:
- make

So, based on the errors I got, I searched about <elf.h> and it seems to be something about Android. To me, it doesn't have any links, I mean, I feel like this.
The thing is, I just downloaded a Linux kernel (Torvalds), I added my syscall, now I'm trying to recompile it and use it with vagrant. That's it. Why does it seem so complicated? I will be honest, I feel completely lost... Do you have any idea if I'm right but I just missunderstood something, or I'm totally out of the good way?
I am working from a MacBook Pro:
MacBook Pro (Retina, 15-inch, Mid 2015)
macOS High Sierra
Version 10.13.1
Thanks for any hints/help

Vagrant
I found a workaround which is vagrant :) With vragrant you can recompile the kernel from a Mac OS. You just have to vagrant init then you connect yourself to the vagrant VM vagrant ssh. Once your inside the vagrant VM, run cd / and you will arrive to the root of your machin, which is also where you created the VM, so you can do whatever you want from Mac OS and compile from the terminal make -j 4 :)
Check your tool-chain. It is not just android thing. https://linux.die.net/man/5/elf.
Please go ahead if you like being challenged. cause this will not be straight forward.
If your task is just compiling code use virtual machine / other linux machine it will be quicker.
But if you are curious to check how things work and getting them work on mac for future compilations without vm. then continue.try adding those header files. in /usr/include as per this
I have access to a server (but don't have root permissions on there). To cut a long story short the admin won't upgrade to the newer version of gcc that I need, but has suggested that I can just install it locally.
I'm having some issues doing this, despite trying to follow the guide at http://gcc.gnu.org/install/index.html. I want to use the new versions of GMP, MPFR, and MPC that are installed now on the server.
I first go into my home dir on the server then mkdir mygcc which I then cd into (this is to be the build dir and is not a sub-dir of src dir), from there I do
/home/username/gcc-4.6.3/configure --with-gmp="/software/gmp-5.0.5" --with-
gmp-include="/software/gmp-5.0.5/include" --with-gmp-lib="/software/gmp-5.0.5/lib"
--with-mpfr="/software/mpfr-3.1.1" --with-mpfr-include="/software/mpfr-3.1.1/include"
--with-mpfr-lib="/software/mpfr-3.1.1/lib" --with-mpc-include="/home/username/usr/local
/include" --with-mpc-lib="/home/username/usr/local/lib" --prefix="/home/username/mygcc"
--with-local-prefix="/home/username/usr/local"
the src files that I unzipped are at /home/pmxlh1/gcc-4.6.3.
I also made the directories /home/username/usr/include, /home/username/usr/local etc and set the prefix flags to try and install various things there, but it also fails if I just leave those flags out for the same reasons.
When I get to make however it ends with
checking for suffix of object files... configure: error: in `/home/pmxlh1/mygcc/x86_64-
unknown-linux-gnu/libgcc':
configure: error: cannot compute suffix of object files: cannot compile
See `config.log' for more details.
make[2]: *** [configure-stage1-target-libgcc] Error 1
make[2]: Leaving directory `/home/pmxlh1/mygcc'
make[1]: *** [stage1-bubble] Error 2
make[1]: Leaving directory `/home/pmxlh1/mygcc'
make: *** [all] Error 2
Not sure if I'm going about this the correct way? But basically I want to install it in my home/dir and so that it uses the correct GMP/MPFR/MPC not the old versions that maybe lurking elsewhere on the server.
thanks for any help
I'm experiencing difficulties with Qt3D. I can't manage to compile it from source code. If possible, I would like to compile Qt3D without compiling Qt itself. Can it link against an already compiled Qt ?
OS: Linux Ubuntu 11.10 (oneiric) x86_64
Qt version: 4.7.4
make output:
cp: cannot create regular file /usr/include/qt4/Qt3D/qt3dglobal.h': No such file or directory
make[2]: *** [/usr/include/qt4/Qt3D/qt3dglobal.h] Error 1
make[1]: *** [sub-threed-make_default-ordered] Error 2
make: *** [sub-src-make_default-ordered] Error 2
global/qt3dglobal.h /usr/include/qt4/Qt3D/qt3dglobal.h
make[2]: Leaving directory/home/soroush/programs/programming/libraries/qt3d-1.0-src/src/threed'
make[1]: Leaving directory `/home/soroush/programs/programming/libraries/qt3d-1.0-src/src'
My solution was to create the /usr/include/qt4/Qt3D folder.
Just type this in a terminal window
sudo mkdir /usr/include/qt4/Qt3D
This fixed the problem for me.
Also you might need to type
sudo mkdir /usr/include/qt4/QtQuick3D
To create the QtQuick3D directory.
Make sure you have qt-devel (or similar) development package installed for Qt. The library-only default package doesn't have headers nor development tools (moc, uic, qmake, etc.).
Alas, your problem seems to be that you're trying to install it to the default prefix /usr without running sudo make install. I suggest you mkdir ~/qt3d && configure --prefix=~/qt3d, so that it gets installed in your home directory.
