Creating and sharing a c++ shared library ?

[vivekian]

Hi ,

These are the steps i followed to create a shared library

1. Compiled the cpp files

g++ -c -g -fpic  -Wall -Wno-deprecated SockException.cpp -o
SockException.o
g++ -c -g -fpic -Wall -Wno-deprecated Socket.cpp -o Socket.o
g++ -c -g -fpic -Wall -Wno-deprecated TcpSocket.cpp -o TcpSocket.o
g++ -c -g -fpic -Wall -Wno-deprecated UdpSocket.cpp -o UdpSocket.o
g++ -c -g -fpic -Wall -Wno-deprecated SocketReaderWriter.cpp -o
SocketReaderWriter.o
g++ -shared -Wl,-soname,libcppsocket.so.1 -o libcppsocket.so.1.0.1
SockException.o Socket.o TcpSocket.o UdpSocket.o SocketReaderWriter.o -
lc

2. Copied the compiled libcppsocket.so.1 to the directories /usr/lib

3. Moved the header files to the directories /usr/include and /usr/
local/include

4. To test the compiled library , i wrote a small program

#include <TcpSocket.h>

int main ()
{
        TcpSocket sock ;
}

where TcpSocket.h is one of the header files copied to /usr/include

5. Compiling this test program

g++  main.cpp
/tmp/ccPqeVa9.o: In function `main':
main.cpp:(.text+0x8a): undefined reference to `TcpSocket::TcpSocket()'
main.cpp:(.text+0x95): undefined reference to
`TcpSocket::~TcpSocket()'
collect2: ld returned 1 exit status

gives the above error.

This i suppose indicates that the library has to be linked. But the
following doesnt help
g++ main.cpp -llibcppsocket

What am i missing here ?

Thanks in advance,
