No longer able to build click with ubuntu distribution and kernel release 3.13

[Roland2014]

Click binary (build of linuxmodule, thus kernel mode, and not the user mode) has been successfully built using ubuntu server 14.04.1 with a kernel 3.13.

Since click commit c91fc67e3db it doesn't compile anymore with this distribution and this kernel release.

Is anybody already encountered this issue and has an idea of the solution?

[kohler]

I haven't. Can you attach your config.log? This may be a bit difficult to fix, but we will try.

Hello, running ./configure --enable-linuxmodule gives me the following output :

Hi, it also occurs in CentOS7.0 64bit(linux kernel 3.10.0-327). "./configure --enable-linuxmodule" says "Your Linux kernel header files cause errors when included by a C++ program.........."

[sakuraliyi]

Who soloved this problem,please help me!Thank you!

[shashibici]

I also has this problem with recent Ubuntu versions. (linux kernel 4.10).

[infinadam]

I have also tried this on 4.10 (xubuntu) and 4.13 (fedora lxde spin). I get the same error:

I have tried creating a symbolic link between include/generated/autoconf.h and include/linux/autoconf.h per @tbarbette on #104, however I still get the same error. Any help would be greatly appreciated.

[tbarbette]

You'll have details of the error in one of the config*log. You'll want to see the output of click-linuxtool.pl.

[tbarbette]

For last versions of the kernel 4.x you may need my pending pull requests also...

[infinadam]

From what I could gather from config.log output, I've tried running click-linuxtool.pl on its own with the following arguments:

click-linuxtool.pl

Which is, near as I can tell given my woefully inadequate shell script experience, should be what configure also ran. I only got Died at linuxmodule/click-linuxtool.pl line 294. as a result.

The actual error I was able to dig out of config.log is as follows:

config.log

This is all under a virtual environment running Fedora 26, kernel 4.13.5.
