problem to compile virtualbox in a debian 32bits with kernel amd64

[Claudio F Filho]

I have a Debian Sid box, running a i386 env, using the kernel 2.6.25-1-amd64. When i try to build the VB, break when try to link to libIDL.*.so. The final part:

....

Some idea?

Sorry, but this will not work. You have to use either a 32-bit kernel and a 32-bit environment or a 64-bit kernel and a 64-bit environment if you want to use VirtualBox. The reason is that VirtualBox is kind of system software which has to communicate closely with the host kernel.
