Some dependencies are not needed in all configurations. The following are some factors that affect the dependency list.
- MiniUPnPc is not needed with
--without-miniupnpc. - libnatpmp is not needed with
--without-natpmp. - Berkeley DB is not needed with
--disable-walletor--without-bdb. - SQLite is not needed with
--disable-walletor--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.
- UniValue is needed only with the
--with-system-univalueoption. Otherwise, if it's missing, a non-standard bundled copy is staticly linked. - ZeroMQ is needed only with the
--with-zmqoption.
- Not-Qt-bundled zlib is required to build the DMG tool from the libdmg-hfsplus project.
