? If you have installed BIND8 using the source code package, this problem should be caused by conflicts between header files and library files. BIND8 installed in source code installs its header files and library files under/usr/local/include and/usr/local/lib by default, however, the BIND8 file in your system is installed under/usr/include and/usr/lib, if your system first uses the/usr/local/include file instead of the header file in/usr/include, and your system's BIND8 library file version is relatively low, a conflict will occur.
?? Solution: add the following parameters during compilation:
?? EXTRA_LDFLAGS =-lbind
?? Note: If BIND8.1.1 is used, the default header file and library file are placed under/usr/local/bind, so this problem will not occur, but for better use, it is best to add the following parameters during compilation:
EXTRA_CFLAGS =-I/usr/local/bind/include
EXTRA_LDFLAGS =-L/usr/local/bind/lib
EXTRA_LIBS =-lbind
