Please help to create a project on vscode + cmake

[alex290]

Hello. I am very interested in your library. Tried to run an empty project on vscode + cmake linux

here is the cmake code

cmake_minimum_required(VERSION 3.20.0)
set(PROJECT_NAME "OpenNNTest")

project (${PROJECT_NAME})


set_property (GLOBAL PROPERTY USE_FOLDERS ON)
set (CMAKE_CXX_STANDARD 20)
set (CMAKE_CXX_STANDARD_REQUIRED ON)

if(UNIX)
	set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}")
	set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}")
endif()


add_subdirectory("${CMAKE_SOURCE_DIR}/opennn/opennn")

file(GLOB project
    src/*
)

add_executable(${PROJECT_NAME} ${project})

target_link_libraries(${PROJECT_NAME} PUBLIC opennn)

code main.cpp

#include <iostream>
#include <sstream>
#include <time.h>
#include <stdexcept>

#include "../opennn/opennn/opennn.h"

using namespace opennn;

int main(int argc, char *argv[])
{
    try
    {
        cout << "Hello OpenNN!" << endl;
        cout << "Bye OpenNN!" << endl;
    }
    catch(const exception& e)
    {
        cerr << e.what() << endl;

        return 1;
    }
}

There are a lot of warnings during assembly, but it is assembled without errors

As soon as I add to main.cpp

....
 try
    {
        cout << "Hello OpenNN!" << endl;
        DataSet data_set("data/iris_flowers.csv",',',true);
        cout << "Bye OpenNN!" << endl;
    }

Stops working

Is there a ready-made empty example for a clean cmake project so that I can put the code.

Hey @alex290 ,
This is my cmake for both windows and Linux. I have managed to integrate opennn into my project:

cmake_minimum_required(VERSION 3.16.0)

set(PROJECT_NAME "MachineLearningCpp")

project (${PROJECT_NAME} CXX C)

set_property (GLOBAL PROPERTY USE_FOLDERS ON)

set (CMAKE_CXX_STANDARD 20)

set (CMAKE_CXX_STANDARD_REQUIRED ON)

if(MSVC)
    # add_definitions (/WX)           # Warnings as errors
    add_definitions (-D_CRT_SECURE_NO_WARNINGS)
else()
    set(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} -g")
    set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -O2")
    # TODO
    # add_definitions(-Werror)
endif()

if(LINUX)
    set(CMAKE_THREAD_LIBS_INIT "-lpthread")
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -pthread")
    set(CMAKE_HAVE_THREADS_LIBRARY 1)
    set(CMAKE_USE_WIN32_THREADS_INIT 0)
    set(CMAKE_USE_PTHREADS_INIT 1)
    set(THREADS_PREFER_PTHREAD_FLAG ON)
endif()

find_package(OpenMP)
if (OPENMP_FOUND)
    message(STATUS "OpenMP found")
    set (CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}")
    set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}")
    set (CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} ${OpenMP_EXE_LINKER_FLAGS}")
endif()

### Eigen

set(EIGEN_SPLIT_LARGE_TESTS OFF CACHE BOOL "Split large tests into smaller executables")
add_subdirectory("${CMAKE_SOURCE_DIR}/libs/eigen")
include_directories("${CMAKE_SOURCE_DIR}/libs/eigen")

#### OPENNN

set(OpenNN_BUILD_EXAMPLES OFF CACHE BOOL "Build OpenNN examples")
set(OpenNN_BUILD_BLANK OFF CACHE BOOL "Build OpenNN blank")
set(OpenNN_BUILD_TESTS OFF CACHE BOOL "Build OpenNN tests")
add_subdirectory("${CMAKE_SOURCE_DIR}/libs/opennn")
include_directories("${CMAKE_SOURCE_DIR}/libs/opennn")

This is my project if you are looking for a template. Although I might make it private later.

It doesn't work anyway. A lot of mistakes fall out. Apparently I have MinGW. killed a lot of time. There is no forum, no support. Sadly. So I wanted to try this library, apparently I will have to look for something else

We work with openNN
You can look at our CMake as an example.
https://github.com/leondavi/NErlNet/tree/onn600/src_cpp/opennnBridge
It works for Linux: Ubuntu and Raspbian and compiles successfully with g++8/11, although we have never tried it with mingw32.
