Computer [SOLVED]
Finally, unbelievable! This is what I love about UNIX systems. You're never hopeless!

So, I've done all the steps, but the problem was actually an endless call of a make option!

I have a script which calls debuild and gives it the `-j' option, then debuild calls dpkg-buildpackage and gives it the same option again, then dpkg-buildpackage calls make and gives it the same option...

I was using -j2, and had already tried changing it, but I ended unsetting it, so it was being called without arguments. From `man make':

Quote:
-j [jobs], --jobs[=jobs]
Specifies the number of jobs (commands) to run simultaneously. If
there is more than one -j option, the last one is effective. If
the -j option is given without an argument, make will not limit
the number of jobs that can run simultaneously.
"make will not limit the number of jobs that can run simultaneously", very enough!.

Also, strange that when called as -j2, it was enough for it to go nuts. Without the option -j, memory usage is relatively low!
See: https://forums.gentoo.org/viewtopic-...6-start-0.html
When compiling icecat, memory usage reached 7GB!!! I still believe this is a bug in make.

EDIT: my intention was using both CPU cores to compile faster, so does it mean it is not possible?

Thank you so much!

cvs-debuild

CVS-DEBUILD(1)						      General Commands Manual						    CVS-DEBUILD(1)

NAME

       cvs-debuild - build a Debian package using cvs-buildpackage and debuild

SYNOPSIS

       cvs-debuild [debuild options] [cvs-buildpackage options] [--lintian-opts lintian options]

DESCRIPTION

       cvs-debuild  is	a  wrapper  around cvs-buildpackage to run it with debuild as the package-building program.  (This cannot simply be accom-
       plished using the -C option of cvs-buildpackage, as it does not know how to handle all of the special debuild options.)

       The program simply stashes the debuild and lintian options, and passes them to debuild when it is called by cvs-buildpackage.  All  of  the
       standard debuild options may be used (as listed below), but note that the root command specified by any --rootcmd or -r command-line option
       will be passed as an option to cvs-buildpackage.  The first non-debuild option detected will  signal  the  start  of  the  cvs-buildpackage
       options.

       The  selection  of  the	root  command is slightly subtle: if there are any command-line options, these will be used.  If not, then if cvs-
       buildpackage is set up to use a default root command, that will be used.  Finally, if neither of these are the case, then debuild will  use
       its procedures to determine an appropriate command, as described in its documentation.

       See the manpages for debuild(1) and cvs-buildpackage for more information about the behaviour of each.

OPTIONS

       The  following are the debuild options recognised by cvs-debuild.  All cvs-buildpackage and lintian options are simply passed to the appro-
       priate program.	For explanations of the meanings of these variables, see debuild(1).

       --no-conf, --noconf

       --rootcmd=gain-root-command, -rgain-root-command

       --preserve-env

       --preserve-envvar=var, -evar

       --set-envvar=var=value, -evar=value

       --lintian, --no-lintian

       --ignore-dirname, --check-dirname
	      These should not be needed, but it is provided nevertheless.

SEE ALSO
