/usr/bin/ld: cannot find during linking g-CodePudding

This question has already been here so many times. But I didn't find the answer.

I have this .cpp file

#include <clickhouse/client.h>
#include <iostream>
using namespace clickhouse;


int main(){
    /// Initialize client connection.
    Client client(ClientOptions().SetHost("localhost"));

    client.Select("SELECT l.a, l.b from table", [] (const Block& block)
        {
            for (size_t i = 0; i < block.GetRowCount();   i) {
                std::cout << block[0]->As<ColumnUInt64>()->At(i) << " "
                        << block[1]->As<ColumnString>()->At(i) << "\n";
            }
        }
    );
    return 0;
}

and I have instantiated SO library, like written here. after that i got the following structure of /usr/local/lib directory:

~/$ ls /usr/local/lib
>>libclickhouse-cpp-lib-static.a  libclickhouse-cpp-lib.so

in next step I trying execute compilation with g

~/$ g   run.cpp -std=c  17 -o result -llibclickhouse-cpp-lib -L/usr/local/lib
>>/usr/bin/ld: cannot find -llibclickhouse-cpp-lib
>>collect2: error: ld returned 1 exit status

I don't know what hinders create links.

thank You for Your help!

CodePudding user response：

ld's manual page describes the -l option as follows (irrelevant details omitted):

-l namespec

--library=namespec

Add the archive or object file specified by namespec to the list of files to link. [...] ld will search a directory for a library called libnamespec.so

If you read this very carefully, you will reach the conclusion that -llibclickhouse-cpp-lib instructs ld to search for a library named liblibclickhouse-cpp-lib.so which, obviously, does not exist.

This should simply be -lclickhouse-cpp-lib.
