Errors & Fix Attempt when building from source with MSVC on windows

[wissem01chiha]

Hi guys, first of all is the project still still maintained or not by the community? , I noticed that there is a lot of issues,many of them are not resolved or/and not answered. however i build it successfully from source ( windows 11, cmake 3.29.0, MSVC 19.40 for x64, MSbuild 17.10.4) , after some changes.
First i used the source code in the v6.0.3, the master branch have an error explained by the issue #305 , i didn't try to solve it, i added the following lines into the main CMakeLists file to disable some warning and errors.

if(MSVC)
    add_compile_options(/EHsc /bigobj)
endif(MSVC)

before the add_subdirectory(opennn), and in the correlations the index var is being modified inside the openMP loop wich is not allowed , so i change it to being updated atomically and change the "i" var to be signed type (openMp is supported by default)

#pragma omp parallel for
    for (int i = 0U; i < v_sort.size(); ++i)
    {
        int repeated = 1U;
        for (int j = i + 1U; j < v_sort.size() && v_sort[j].first == v_sort[i].first; ++j, ++repeated);
        for (int k = 0; k < repeated; ++k)
        {
            x_rank_vector[v_sort[i + k].second] = rank + (repeated - 1) / 2.0;
        }
        //i += repeated - 1;
        //rank += repeated;
        #pragma omp critical
        {
            rank += repeated;
        }
    }

there is a similar issue i think in #287 with openMP
build with:

mkdir build & cd build 
cmake ..
msbuild opennn.sln

The project should be succesfful build, anyone tested the other next tags ? v6.0.4 and v6.0.8 ?

The last commit (as of 16/01/2025) was made two days ago on the dev-branch. So I guess its still active!

Yeah, no - I think its dead. There isn't a single productive commit from the main devs.

@distortedMango Hi, yes, I noticed that too. However, I think I will create a fork to maintain it, since I am planning to do some experiments in ML with C++
