Bret Brown C++ Infrastructure https://gitlab.kitware.com/bill-hoffman 3Goals 4Non-goals (so far) ● Package archive formats ○ .deb, .rpm, .pkg.tar.zst, NUPKG ● Package managers ○ APT, RPM, PKGBUILD, WPM ● Source repository structure workflows ○ ./configure && make && make install Why not? Scope and adoption friction! 5Then what? ● Package archive contents ○ i.e., dpkg-deb --contents fangorn.deb ● Metadata file(s) to declare those contents
