I 'm trying to compile a package in Ubuntu but getting error

"linux/autoconf.h: No such file or directory"

Now I see that the missing file is under /usr/src/linux-headers-2.6.38-11-generic/include/generated".

Where do I have to copy this file in order for the program to compile? I'm new to linux so please be specific if possible.

Update: Ok making progress. I think I have to copy the autoconf.h to a default location where the Linux kernel can find it.

I'm using Ubuntu 11.04. This is how my /usr/src folder looks like:


Anyone know where I should copy the autoconf.h file?

Thanks in advance.

You might have better luck asking in Super User. However, this is programming related so I'm not going to downvote it. –  Michael Oct 7 '11 at 1:21
a shot in the dark, have you actually autoconf installed? There is no general autoconf.h file, its always generated in a configure process. –  evildead Oct 7 '11 at 1:27
yes the autoconf.h file exists. I mention that on my question. The problem is that I'm new to Linux and I don't know where it should go in order for my program to find it. –  Marquinio Oct 7 '11 at 1:29
What are you trying to compile? Is it a kernel module? –  derobert Oct 7 '11 at 1:42
Its a USB driver –  Marquinio Oct 7 '11 at 1:46

You are trying to compile an external module. Modules need info on how the kernel was configured. However, this file has moved from linux/autoconf.h to generated/autoconf.h so the right thing to do is :

  • find the file including autoconf.h
  • replace this line with the following code :

I have to include something here for code formatting to work

#include <linux/version.h>
#include <linux/autoconf.h>
#include <generated/autoconf.h>

Thanks this actually fixed problem. I know this driver works in Fedora10 and was probably written for 32-bit. I'm now trying to compile it in 64-bit and getting weird compilation errors. I guess I would have to rewrite the driver for 64-bit? –  Marquinio Oct 11 '11 at 4:09

try copying it into /usr/src/linux-headers-2.6.38-11-generic/include/linux or /usr/src/linux-headers-2.6.38-generic/include/linux, depending on which kernel your currently using

It would be better instead of copying, symlink. –  Balder Mar 16 '13 at 15:07
