[Pkg-virtualbox-devel] Bug#785161: Bug#785161: kbuild: module-assistant fails to build virtualbox-source

[Gianfranco Costamagna]

Hi Lorenzo,

I can reproduce, but couldn't this be a problem of m-a?

I would like to reassign, maybe m-a is using the wrong build system for virtualbox, and just by chance it worked before.

cheers,

G.

The sequence is
# apt-get install virtualbox-source
# m-a update
# m-a prepare
# m-a build virtualbox-source

the last command is supposed to create a .deb package but the building process fails at about 30%; as a result you can view the build log

Please post the *exact* sequence you run in order to spot the problem.
