Right, except users might want to build packages themselves, in that case they would have to install the Build-Depends on the machine or chroot where they are doing the building.

Thanks, that does help a lot, and it helped me to realize that the packages are built on the Debian machines and sent to users already built, so there's no need for the users to install the Build-Depends, right?

No. The purpose of the build process is to generate a product that is ready to install. The build dependencies are not needed after the build is complete. -- \ “Pinky, are you pondering what I'm pondering?” “Well, I think | `\ so, Brain, but pantyhose are so uncomfortable in the | _o__) summertime.” —_Pinky and The Brain_ | Ben Finney

Re: Build-Depends vs Depends
Thank you, Octavio. Does this mean apt will temporarily install the Build-Depends packages and remove them after the installation completes?

For example, a compiler is needed during build time, but it's not needed to run the program so it would qualify for Build-Depends but not for Depends. Build-Depends is used during "apt build-dep" (used for compilation and building the package) and Depends is used during "apt install". Best regards. -- Octavio.
Re: Build-Depends vs Depends
Taylor Klinewrites: > What is the difference [between the “Build-Depends” field and the > “Depends” field]? The difference is precisely that between building the package from source, versus using the package installed. The “Build-Depends” and “Build-Depends-Indep” fields appear only in the source package stanza. The “Depends” field appears only in a binary package stanza. See Debian Polcy §5.2 for a summary, and §5 generally for a description of what these fields mean. > How are they treated differently during the apt installation process? The installation process (the ‘dpkg’ tool does the actual installation of an individual package) cares only about “Depends”, the declaration of what other packages must be installed for this one to work. The package build servers care about “Build-Depends” and “Build-Depends-Indep”, because the job they're doing is not to use the package but to build it from source. -- \ “Computers are useless.

Re: Build-Depends vs Depends
Build-Depends should not make any effect during package installation process, because it's a dependency only for package-building process. __ I'm using this express-made address because personal addresses aren't masked enough at lists.debian.org archives.

Re: Build-Depends vs Depends
Taylor Klinewrites: > What is the difference? How are they treated differently during the > apt installation process? Thanks :) Build-Depends is used only during build-time. (Usually on the buildds, though it can be on developer's computers as well.) Depends, on the other hand, are packages that are required for the package to /run/, and must be installed on the users' machines. For certain packages that are interpreted, rather than compiled, these are frequently the same list. (Think: python packages that don't have C extensions). Hope that makes sense!

Build-Depends vs Depends
What is the difference? How are they treated differently during the apt installation process? Thanks :)
