make have errors after install all the dependencies

[FOSquare]

Hello, I follow the tuturial, after I install dependencies correctly. I compile the program by "make" in the folder of /xdp-tutorial, but I have the following errors. Thanks.

Did you run 'git submodule init' and 'git submodule update' ?

[FOSquare]

Yes, and I could find that libbpf was successfully added in the repository.

Same error as I run on another server. Could you help me? Thanks. My OS is Ubuntu 16.04.6 LTS \n \l

I try to run it in another server. still met problem. The same procedures as shown in the toturial. the kernel version is 4.15.0-20-generic. Thanks.

Hmm, it may just be that your kernel headers are too old. You are going to need a newer kernel to run the examples anyway, at least 4.19.

Since you're on Ubuntu, you should be able to get a newer kernel package (and headers) from the kernel-ppa at https://kernel.ubuntu.com/~kernel-ppa/mainline/

I faced this same problem as FOSquare on my desktop with Ubuntu 19.04 "kernel 5.0.0-13-generic". My ubuntu packages include the following :

I followed setup_dependencies.org, and the dependencies of this tutorial has been correctly done. Maybe I think that update of "xdp_tutorial/headers" directory is one of cause of this compile error. Currenty, I modify clang command area in common/common.mk to add -I/usr/include/x86_64-linux-gnu/ line, then I can compile "basic01" program.

By downloading and installing: linux-headers-4.20.0-042000_4.20.0-042000.201812232030_all.deb linux-image-unsigned-4.20.0-042000-generic_4.20.0-042000.201812232030_amd64.deb linux-modules-4.20.0-042000-generic_4.20.0-042000.201812232030_amd64.deb

I update my kernel version to 4.20.0-042000-generic. I still have the same problem....

Thanks.

[FOSquare]

what do you mean by adding -I/usr/include/x86_64-linux-gnu/ line in common.mk? I tried, but after I added "-I /usr/include/x86_64-linux-gnu/" in the common.mk. I have ./common//common.mk:13: *** missing separator. Stop.

Thanks.

[tohojo]

Right, with the latest batch of changes you should at least be able to compile things even on old Ubuntu installs. Whether or not the result actually works is a different matter, but do try it out ;)

[liuqun]

Hi, @tohojo and @FOSquare !

Add '-I/usr/include/x86_64-linux-gnu' is just a temporary walk-around solution! Please try:

sudo apt-get install -y gcc-multilib

Then revert commit 77edd02.

The gcc-multilib debian package makes a symbol link at "/usr/include/asm" to "/usr/include/x86_64-linux-gnu"
