Controlling dependencies

Some dependencies are not needed in all configurations. The following are some factors that affect the dependency list.

Options passed to ./configure

• MiniUPnPc is not needed with --with-miniupnpc=no.
• Berkeley DB is not needed with --disable-wallet.
• Qt is not needed with --without-gui.
• If the qrencode dependency is absent, QR support won't be added. To force an error when that happens, pass --with-qrencode.
• ZeroMQ is needed only with the --with-zmq option.

Other

• librsvg is only needed if you need to run make deploy on (cross-compilation to) macOS.
