            Visual Studio 2017: build tools for v142 cannot be found error, even though Platform Toolset is set to v141
            Asked 2021-Jan-07 at 00:40

            I'm building an openFrameworks project (using the project generator which generates VS2017 solutions) but am receiving the "build tools for v142 cannot be found" error. Answers across Stack Overflow say to go into Project > Properties > Configuration Properties > General and set Platform Toolset to v141 in order to downgrade, however my project fails to build with the same error even after doing this.

            As @dxiv mentioned in the comments: "The error references one project, but the Property Pages refer to another." Every project in the solution (there should be two for OF projects, yourProjectName and openframeworksLib) needs to be individually downgraded. Instead of going to Project > Properties via the top toolbar, right click on each project in the Solution Explorer and get to the Properties menu for each of them from there.

            And I just realized the top toolbar's Project menu item coincides with whatever item you currently have selected from the Solution explorer.

            MinGW Installation Manager - Missing devpropdef.h file
            Asked 2020-Dec-10 at 20:06

            I downloaded the MinGW Installation Manager and installed most of the packages available there in trying to find the 'devpropdef.h' file.

            This file is needed by the openframeworks library and without it, I cannot compile the most basic project.

            This file was listed by one of the contributors in this thread, but I don't know what happened to it.

            Does anyone know which package it is in from the MinGW installation manager? Or how I can get my hands on it?

            pass any object to function to create this object
            Asked 2020-May-14 at 14:05

            I'm making a small generative video layering software using openframeworks and c++. To this effect I have one main class, one layer class and a lot of different types of video/simulations class. I need to make it so that when I press a key, a different simulation is loaded.

            I have two questions :

            1. How can I access a list of all my simulation classes ?
            2. Following up, how can I feed one choice from this list into a function that can take any type of object and initiate it ?

            I made a drawing instead of using to code brackets to have all 3 blocks on the same horizontal level (actual code is underneath).

            Here's the main.cpp and the layer.cpp in code for clarity :

            Best method to do this is to use something called the factory pattern.

            Basically, define a function that takes an argument of some defined type that can be used to figure out what kind of simulation you want, and then create that simulation and return a pointer to it.

            A simple version of it might look like this:

            LNK1104 for unneeded library
            Asked 2020-Mar-03 at 14:33

            I am trying to include the Boost Library in my OpenFrameworks project, in particular it is When I add the boost root directory to the Additional Include Directories of a new project, I see the error LNK1104 cannot open file 'libboost_filesystem-vc141-mt-gd-x32-1_72.lib', although I don't even need the filesystem library.

            However, when I added the boost root directory to the Additional Include Directories of a freshly create c++ console project, the error does not show, and I can make use of the library without problems.

            Runtime Library is /MDd.

            What might cause this problem? A broken build of boost?

            Taken from the comments to the question. Although this is unusual it could be that a header in one of the dependencies of your project has the same name as a header in the filesystem library. And since you put boost first in the Additional Include Directories the boost header was included instead of a header from a different library. By default with Visual Studio boost automatically inserts link commands using a #pragma comment(lib, libname) so including this header will cause a link dependency.

            A solution to try in this case is to move boost to the end of the Additional Include Directories so when the compiler searches for the header it will find the one from the previous dependency first.

            It's a typo. : should be ::. You can see it being correct in the fourth code block of the linked examples, while the previous two were, presumably, copy-pasted with the same error.

            It may, however, be confused as a label, but a label cannot be placed in such contexts.

            I tried running the same code in Visual Studio Code and it debugged like normal but I need the 2017 version for a class.

            First, please check whether you have opened a solution or a project rather than a cpp file. In general, all the debug configuration info are stored in the xxxx.vcxproj file and .vs hidden folder which belog to the whole project.

            Solution

            First, try to click File-->Open-->Porject/Solution to open .sln or xxx.vcxproj file. Besides, right-click on the project which you want to debug to click Set as StartUp Project.

            Note: each project can only has one main cpp file. Or you can just add these codes into the main cpp file directly.

            If the steps above did not work, please try these:

            1) exclude this project from your solution(remove it) and then build your solution without it.

            2) you should again add your project into the current solution and then build your solution and set it as Start Up Application.

            In addition, if you cretae the OpenFrameworks project with other third party tool to generate it and then open the project in VS2017, I think you cannot do this. Incompatibilities and other issues can arise because the project itself generated by other tools is not the same as the project structure created by VS2017.

            So try these steps to create OpenFrameworks projects with VS2017:

            1) install openFrameworks extension on Tools-->Extension and Updates.

            2) After that, when you create the openFrameworks project in VS2017, do not forget to add the folder path of of_v0.11.0_vs2017_release which is downloaded from this link.

            You can follow this guidance to get more detailed steps.

            3) After that, you can try to add these codes in main.cpp file.
