main() first defined here - c++

Question

I'm trying to compile my project in Eclipse.
However, it says that the main() is defined more than once. I grep'd my project dir and it found only one definition of main(), in main.cpp.
Apparently it is somewhere else.maybe a dir I linked to.
The only dirs I linked to are:
-ljson_linux-gcc-4.5.2_libmt
The compiler output is:
make all

s = "/lol2#/idan.html";
cout << hregex::CheckURLField(s)<< "= /lol2#/idan.html" << endl;
return 0;
}
How can I prevent the error from appearing?

Answer 1

g++ says serv.o has a main function.
If there actually is no main() it serv.cpp, check the includes, maybe you did a bad #include and included a .cpp instead of a .h ?
As an extra remark :
it tries to bind against the library "-ljson_linux-gcc-4.5.2_libmt"
So there is "-l-ljson_linux-gcc-4.5.2_libmt" in the link command line. Remove the -l in your configuration
