drahflow / crawler Goto Github PK

Hello author,

Today I am going to study the crawler based on your code. But after I downloaded and built (both under Windows with cygwin & Ubuntu 16.04), it said that it failed to locate the library adns.

The log is attached below:

carl@ubuntu:~/myCrawler/crawler$ make
g++ -std=c++11 -W -Wall -Wextra -Wno-missing-field-initializers -Werror -O4 -ggdb -pg -fprofile-arcs -ftest-coverage -c -o tests.o tests.c++
g++ -std=c++11 -W -Wall -Wextra -Wno-missing-field-initializers -Werror -O4 -ggdb -pg -fprofile-arcs -ftest-coverage -ladns -o tests tests.o
/usr/bin/ld: cannot find -ladns
collect2: error: ld returned 1 exit status
Makefile:8: recipe for target 'tests' failed
make: *** [tests] Error 1

Would you please give me some clues on this?

Many thanks,

My e-mail: [email protected]

Carl.
