hardened-malloc package build failed - Unpacking llvm-7-dev (1:7.0.1-8) ... - E: Sub-process /usr/bin/dpkg exited unexpectedly

Original bug report:


@onion_knight

Continuing the discussion from Whonix Desktop Installer with Calamares - field report:

First, try to build package security-misc (or any other known good package for testing). That is a prerequisite exercise.

Then, move on to be building the failing hardened-malloc package the “easy” way.

See:

https://www.whonix.org/wiki/Dev/Build_Documentation/security-misc

The build process of building any of the packages by Whonix developers is always very similar. This very wiki page explain how to build package security-misc . By replacing the name of the package security-misc with the name of any other package you might be interested in building, the other package would be build.

Does that work for you?


If that works for you, let’s move on building a known good pacakge using cowbuilder.

build-steps.d/1100_prepare-build-machine sets up a chroot in /var/cache/pbuilder using cowbuilder.

Will follow up with instructions on how to build a package using cowbuilder.

Ok, step by step.

First, building security-misc.
Fails at make deb-all-dep (" Build and Install the Package") stage:

That wasn’t the best example. It would require either

Try this package instead perhaps: https://github.com/Whonix/helper-scripts
because that does not have other Whonix packages it depends on which need to be (build/)installed first.

OK, building helper-scripts worked without error.

How to build hardened-malloc? git clone command does not work

Typo. Not -. It’s _.

git clone https://github.com/Whonix/hardened_malloc.git

Thanks!

make deb-all-dep
make: *** No rule to make target 'deb-all-dep'.  Stop.

Using

git describe

There is a Makefile inside the directory though.

Wrong tag. I wonder why git master for you points at PQ3A.190705.001.2019.07.16.22

Symptom missing genmkfile (you don’t have this symptom):

user@disp6713:~/hardened_malloc$ make deb-all-dep
Makefile:147: /usr/share/genmkfile/makefile-full: No such file or directory
make: *** No rule to make target '/usr/share/genmkfile/makefile-full'.  Stop.

Did you clone from https://github.com/GrapheneOS/hardened_malloc or another place? That wouldn’t work - does not have Debian packaging.

In summary…

git clone https://github.com/Whonix/hardened_malloc.git
git tag -v 0.5-1
git checkout 0.5-1

seems ${shlibs:Depends} is not defined

Just drop

${shlibs:Depends}

Run

sudo apt-get --yes --no-install-recommends install debhelper genmkfile clang llvm-7-dev clang-tidy

As per:

Install build dependencies. It might be possible to let genmkfile do that.

make deb-all-dep

If that did not work, have a look in debian/control file and manually install all packages listed under Build-Depends and Depends .

Dependency installation isn’t a big deal. Isn’t done during actual package build.

make deb-all-dep is fixed in genmkfile git master. make deb-all-dep is just a convenience feature which unfortunately broke due to ${shlibs:Depends}.

Ok, removed ${shlibs:Depends} from debian/control

Build successful

This:

After cowbuilder debugging we can try build known good packages using cowbuilder followed by building the failing package using cowbuilder.

Also using cowbuilder for package builds can be disabled.

By setting make_use_cowbuilder=false build configuration.

sudo make_use_cowbuilder=false ./...

Add make_use_cowbuilder=false after sudo and before ./whonix_build.

Or by setting it through any other way as per build configuration.

Builds using cowbuilder are better:

  • makes sure no extraneous files are included in the build - since it builds them in chroot
  • makes sure that no dependencies are missing in debian/control
  • i.e. if package can be build in chroot, anyone should be able to build it in most cases - except a weird bug such as this one. This one is perhaps in top 3 most weird bugs ever.

It’s important (much better at least) that release builds are build that way but not so much for testing/debug builds.
