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 --without-miniupnpc.
• libnatpmp is not needed with --without-natpmp.
• Berkeley DB is not needed with --disable-wallet or --without-bdb.
• SQLite is not needed with --disable-wallet or --without-sqlite.
• 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.
• If the systemtap dependency is absent, USDT support won't compiled in.
• 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.
• Not-Qt-bundled zlib is required to build the DMG tool from the libdmg-hfsplus project.
