compiling libpqxx project error

[Vitamin]

Hi,

Via the ports tree, I installed the following:

postgresql-libpqxx 4.0
postgresql84-client 8.4

Test code:

#include <iostream>
#include <pqxx/pqxx>

using namespace pqxx;
using namespace std;

int main(){

  connection c;

}

Compile command:

g++ sqlTest.cpp -o sqlT -I /usr/local/include -lpqxx -lpq

Error generated

/usr/bin/ld: cannot find -lpqxx

Any suggestions why are these files not in that folder after installation? Any solutions?

If I tried:

g++ sqlTest.cpp -o sqlT -I /usr/local/include

Error generated:

Any suggestions to a solution?

thank you

Not sure but try adding

-L /usr/local/lib

to the g++ command.

Thanks for the reply, solution found.

EDITED

Instead of this command, which generates an error:
[cmd=]g++ sqlTest.cpp -o sqlT -I /usr/local/include -L /usr/local/lib [/cmd]
I should have also included the suggestion by SirDice, along with the files
[cmd=]g++ sqlTest.cpp -o sqlT -I /usr/local/include -L /usr/local/lib -lpqxx -lpq[/cmd]

The compiler could not find those files because they were in another file, the lib folder. Thanks for the help.
