[Bug 994080] Re: dpkg-buildpackage doesn't use multicore CPUs

[Raphaël Hertzog]

Hello,

dpkg-buildpackage's -j option enables concurrency within "debian/rules"
but it only sets the "parallel" option in DEB_BUILD_OPTIONS for packages
to act upon. So if it doesn't work in your case, it's because your
package is not implementing it and not because dpkg-buildpackage is
broken.

There's nothing to fix at the dpkg-buildpackage level, please file bug
reports against the packages that would benefit from enhanced support of
the parallel option.

Title:
  dpkg-buildpackage doesn't use multicore CPUs

Status in “dpkg” package in Ubuntu:
  Invalid

Bug description:
  The dpkg-buildpackge command doesn't honor the -j* parameter, i.e. it can't use multiple threads for compiling.
  Building packages takes much longer as only CPU core is used in the process...
