Some dependencies are not needed in all configurations. The following are some factors that affect the dependency list.
- MiniUPnPc is not needed with
--with-miniupnpc=no. - Berkeley DB is not needed with
--disable-wallet. - protobuf is only needed with
--enable-bip70. - 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-zmqoption.
- librsvg is only needed if you need to run
make deployon (cross-compilation to) macOS.
