Questions tagged [dependencies]

Additional software that some software requires to function

The dependencies of a software package are the other packages that it requires. The concept covers both runtime dependencies (what needs to be installed in order for the software to work) and compile-time (or build-time) dependencies (what needs to be installed in order to compile the software).

This tag is typically used alongside or or a specific package manager (, , …) for runtime dependencies, or alongside for build-time dependencies.
