Unable to compile kqemu

[Teo]

My Ubuntu is Edgy and I can't compile Kqemu kernel module (kqemu from qemu project page).

Got:
build-essential
linux-image-2.6.17-10-generic
linux-image-generic
linux-headers-2.6.17-10-generic
linux-headers-2.6.17-10
linux-headers-generic
linux-source-2.6.17
linux-source

Here's some code

tomek@teo:~$ cd kqemu-1.3.0pre9/

Did it once (same way) in Dapper and successfully compiled. What's wrong? Why 'make' can't find this file?

BTW why there's no kqemu package in repos?

Hello, I have successfully compiled kqemu recently on my edgy installation using the instructions from and italian blog, http://pollycoke.wordpress.com/. I suppose you don't read italian, so I give you an english summary of the steps to follow:

1. Get qemu 0.8.2 and kqemu 1.3.0pre9 sources;
2. extract qemu and kqemu inside the qemu directory, i.e.

   tar zxf qemu-0.8.2.tar.gz
   cd qemu-0.8.2
   tar zxf ../kqemu-1.3.0pre9.tar.gz

3. configure qemu compilation

   ./configure --disable-gcc-check --disable-gfx-check

4. move to kqemu directory, configure, compile and install

   cd kqemu-1.3.0pre9
   ./configure && make && sudo make install

5. finally, create the file /etc/modprobe.d/kqemu with the following content

   options kqemu major=0
   install kqemu /sbin/modprobe --ignore-install kqemu && chmod 666 /dev/kqemu

Hope this works.

Are you sure it didn't work? It's only a warning, and it seems the kqemu module was built anyway.

http://fabrice.bellard.free.fr/qemu/qemu-accel.html :

Try it
The QEMU Accelerator Module is available in the Download area. Be aware that unlike the rest of QEMU it is a closed source proprietary product with a specific license.
Terms of Use
The QEMU Accelerator is free to use, but it is a closed source proprietary product. You are not allowed to distribute it yourself to other people without an explicit authorisation. Distributors wishing to include the QEMU accelerator on CDs, ISO images or packages must contact the author to know the exact terms.

To say truth, I did not check. Well it's working anyway

THX both of you (gborzi and shining) for help .

I think kqemu is now released as an open sourced GPL product.
