Re: [Outreachy] Hi all!

Dear all,

I am sorry for the late answer! This is just an update on my last tries to get the source of tophat and run a test with sbuild ;)

As Diane suggested in the last email , i downloaded and installed (at least tried too) the sbuild package on my linux mint machine. I followed the instructions of the Debian wiki and i also installed the libsbuild-dev. Things seemed to work up until that point.

I then followed the commands 'apt source tophat' , 'apt build-dep tophat', 'cd usr/source/tophat', 'dpkg-buildpackage', which went also well.

However, when i tried 'sudo sbuild -d unstable' , after running for a while i get an error : 'E: Build failure (dpkg-buildpackage died)'.

I think the error connected to that (last lines of the log) is that :

'/usr/include/c++/7/bits/stl_pair.h:519:5: note: template argument deduction/substitution failed:

tophat_reports.cpp:2707:128: note: cannot convert ‘junction_stat’ (type ‘JunctionStats’) to type ‘JunctionStats&&’

gtf_junctions.insert(make_pair<Junction, JunctionStats>(Junction(ref_id, left_coord, right_coord, antisense), junction_stat));'

I can also send you more details if you wish (e.g the summary) , i am sorry i do not know very well how to report all these.

Finally , i would like to tell you that since my PhD thesis deadline is postponed to the end of January , i will probably won't make it to apply to the Outreach program for this round... which is really sad. However , with your permission, i would like to keep on working on running tests and get more familiar with the whole process. And hopefully i will be able to apply for Outreach's next round!

Thank you all very much,

Katerina

I have one question : all the examples in the part of the tutorial for setting up the development environment (i.e sudo apt-get install rerun ruby-foreman apt-cacher-ng

moreutils lighttpd rabbitmq-server) are relative to the specific package of 'rubby'? So when i want to set up the environment for running test in another package i will have to change these commands accordingly?

I suspect apt-cacher-ng is in there as a performance enhancement.

apt-cacher-ng can help speed frequent rebuilding of packages because it can download and store locally packages.

When you're first starting to test build an application you'd do:

apt source <package name>
apt build-dep <package name>
cd <package directory>
dpkg-buildpackage

(with the stretch release they added apt as an improvement to apt-get)

Debian maintianers will usually build packages in a temporary environment using tools like pbuilder or sbuild. Those tools automate extracting the package, installing the dependencies, building, and running tests. It's just a bit of work to get them setup.

And it looks like autopkgtest expects to be running in a temporary build environment so it can install things and change the system configuration.

Hope that helps
Diane
