I am trying to do some socket programming, writing a simple client-server program. But when I try to compile the program, I get this error.
gcc -o showip showip.c -lnsl -lsocket -lresolv
showip.cc: In function ‘int main(int, char**)’:
/usr/bin/ld.real: cannot find -lsocket
collect2: ld returned 1 exit status
I try to install lib doing this,
sudo apt-get install happycoders-libsocket-dev
and when I compile, I still get the same error.
How can I get rid of this ? Thanks.
Normally the library binary comes with one package and the headers with another one with tha same name and a "-dev" behind.
Maybe you are missing plain happycoders-libsocket.
You are missing this package happycoders-libsocket, assuming you are in ubuntu.
Apparently happycoders-libsocket package in ubuntu is placing the libsocket.so libreary in /usr/lib/happycoders/ and that is not a standard place for libs, it should be directly inside /usr/lib/. Using -L you instruct the compiler, or linker in this case, to search for library files in that extra directory
