The problem is just that the dnsmasq Makefile does not call pkg-config with the --static option when being built statically. Compare the output of: $ ./output/host/usr/bin/pkg-config --libs dbus-1 -L/home/thomas/projets/buildroot/output/host/usr/mipsel-buildroot-linux-uclibc/sysroot/usr/lib -ldbus-1 against the output of: $ ./output/host/usr/bin/pkg-config --static --libs dbus-1 -L/home/thomas/projets/buildroot/output/host/usr/mipsel-buildroot-linux-uclibc/sysroot/usr/lib -ldbus-1 -lpthread -lrt Best regards, Thomas
