This section assumes some knowledge of the latter. -However, Qt makes extensive use of runtime dependency detection. -In nixpkgs, those runtime dependencies are made into build dependencies through wrappers. +The major caveat with Qt applications is that Qt uses a plugin system to load additional modules at runtime, +from a list of well-known locations. In Nixpkgs, we patch QtCore to instead use an environment variable, +and wrap Qt applications to set it to the right paths. This effectively makes the runtime dependencies +pure and explicit at build-time, at the cost of introducing an extra indirection. ## Nix expression for a Qt package (default.nix) {#qt-default-nix} |
