deb-rust-hello

building a rust program into PPA

the journey:

install deb building tools like debhelpers
using debmake to scaffold the project, need to build a deb-rust-hello.tar compression file in the previous folder, the debmake error will tells you how, then simply run debmake
write a Makefile
follow the popsicle repo to modify the debian/rules file for rust
run debuild this should be build success
register or login a Launchpad account
register a GPG key for your account, I was using my Github GPG key for this
modify the debian/changelog from UNRELEASED to the ubuntu code name, my case is focal
run debuild -S -k to sign the building
go to upper level folder then run debsign -k .changes to sign the source.changes file
now facing the ubuntu build server cannot find cargo command
found out this article that I need to vendor the compiling tools up to launchpad...
let me cry for a bit... there must be a easy way to do this...
after reading this article
I tried to add the Mozilla Security Team PPA as my building dependency
modify my control file like this to add cargo as build-depends
dput a new version then the build success!
