Having issues compiling C code (sqlite) libdl.so not linked

just to simplify the above question:

including boilerplate start of new project code with a call to dlopen.
**main.cpp**

#include <iostream>
#include <dlfcn.h>

using namespace std;

int main() {
    cout << "Hello, World!" << endl;

    char * file = (char*)"/path/to/file";
    dlopen(file, RTLD_NOW);


    return 0;
}

** CMakeList.txt **

cmake_minimum_required(VERSION 3.1)
project(testDLopen)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -ldl  -std=c++11")

set(SOURCE_FILES main.cpp)
add_executable(testDLopen ${SOURCE_FILES})

in CMake tab > Cache I also added the -ldl flag to "CMAKE_C_FLAGS"

the above fails to compile as in the original question.

Hi Narunas!

Please try the following CMakeLists.txt, it works for me:

cmake_minimum_required(VERSION 3.1)
project(testDLopen)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(SOURCE_FILES main.cpp)
add_executable(testDLopen ${SOURCE_FILES})
target_link_libraries(testDLopen ${CMAKE_DL_LIBS})

Thanks Anna - this appears to have solved the issue - the test program and the one that uses sqlite3 now compile!
Again, thanks!
Narunas
