Hello! Thank you for making and uploading a template for us beginners! My only question is how can we build it on windows and cmake? :( |

Hi @ybtre ! Good question, I realize I should have added some instruction about this in the README 🤔 I'll suppose you don't have anything installed on your PC: no C toolchain, no CMake, no IDE.. I suggest you use the Scoop package manager to install all the necessary dependencies. To do so, install Scoop by following the instructions on the website and then open a terminal and: # install cmake and c compiler toolchain
scoop install cmake gccOnce the installation finishes you should have everything you need to build and run this repo. You could do it from the command line but if you're just starting then I suggest you don't go through that route, at least not initially, and instead work with an IDE that handles all the building and running commands for you. I've found VSCode to be really good for C/C++ development, so I'll suppose you're going to use that as well. Once you install VSCode on your PC, install the C/C++ tools extension, which is what will actually enable the IDE to manage the CMake project for you. With the extension installed now you can open the repo in VSCode (btw, make sure to pull the latest changes, I uploaded a change just when I was writing this that fixes an issue with CMake sometimes not finding the dependencies to download). The first thing you'll want to do is tell VSCode which C compiler you want to use. You can do this by clicking on the label
And that's it! It should be more than enough to get you started and play with the code. Let me know if you encounter any issues or if you want me to elaborate more in detail about any of the points above |

Hello! Thank you for the quick and elaborate reply. Appreciate going through it as if someone is starting from a fresh windows install. Which ill have to do soon, currently I had everything installed but initially I tried using either the terminal or the CMake gui to build the project (tho I'm very new to both of them and I couldnt figure it out) The issue I'm running into following your explanation is when I press build and the errors I get are with the mutex in the box2d dependancy as shown in the screenshot ;/ I tried including it at the top of the header file but to no avail. Not impossible that its something related to my windows install and a path not being setup properly ;/ |

hmm interesting, could you tell me which version of
could be but I don't think so 🤔 a nice thing about this setup is that CMake should take care to get and setup all dependencies for you (box2d, etc.) and there's no need for you to have anything except the C compiler toolchain installed. Now, it could be that VScode is using a GCC version that's too old? Although that means you're using a really old version 😅 since std::mutex should be available starting from C++2011 (as far as I see here). Anyway, I would suggest to check if you're using the correct GCC version, hopefully the same as I have in my screenshot above if you installed GCC through Scoop. Let me know how it goes 😄 |

GCC shouldnt be the issue, looks like a newer version :D. Weirdly enough I noticed that if I press the Play button on the bottom the game runs and the errors disappear, they only appear if I press build o.o this is my entire bottom row in vscode These are my available compilers too

ok that's good to know!
yeah that is very weird 🤔 I would be interested in seeing the output of the CMake build, in the For example, if I do a clean build (by removing the Clean build logAnother thing that might be useful to see is your "cmake configure" log. Open the command panel in VSCode ( Cmake: configure logSo my new hypothesis is that CMake is not finding the proper std libraries. The |

This is the output tab after I deleted the build folder and pressed build in vs code using gcc 12.2.0 Outputand this is the CMake: Configure output Cmake: configure log``` [main] Configuring project: raylib-cpp-cmake-template [proc] Executing command: C:\Users\hristo.vuchev\scoop\shims\cmake.EXE --no-warn-unused-cli -DCMAKE_EXPORT_COMPILE_COMMANDS:BOOL=TRUE -DCMAKE_BUILD_TYPE:STRING=Debug -DCMAKE_C_COMPILER:FILEPATH=C:\mingw64\bin\gcc.exe -DCMAKE_CXX_COMPILER:FILEPATH=C:\mingw64\bin\g++.exe -SC:/Users/hristo.vuchev/Documents/WorkVerse/PongProject/raylib-cpp-cmake-template -Bc:/Users/hristo.vuchev/Documents/WorkVerse/PongProject/raylib-cpp-cmake-template/build -G "MinGW Makefiles" [cmake] Not searching for unused variables given on the command line.

Im planning on doing a fresh install on my laptop over the weekend and will try it there as well |

ok the build log looks fine, at least there is nothing unexpected there. However in the configure log I do see some interesting things. For instance, it seems CMake is using I'm not sure why this is failing though, Another thing we could do to troubleshoot is do the commands directly from the terminal so we have full control on what's going on. Something like this # first, delete `buid/` and close VSCode to avoid having it do unexpected things
# from the root of the project (change the paths to CMake, GCC, and the project itself to your own paths)
# This is the `Configure` step
C:\Users\andreatupini\scoop\shims\cmake.exe --no-warn-unused-cli -DCMAKE_EXPORT_COMPILE_COMMANDS:BOOL=TRUE -DCMAKE_BUILD_TYPE:STRING=Debug -DCMAKE_C_COMPILER:FILEPATH=C:\Users\andreatupini\scoop\shims\gcc.exe -DCMAKE_CXX_COMPILER:FILEPATH=C:\Users\andreatupini\scoop\shims\g++.exe -SC:/Workspace/Personal/raylib-cpp-cmake-template -Bc:/Workspace/Personal/raylib-cpp-cmake-template/build -G Ninja
# now we can go ahead and actually build everything with
cd build
# note, you might need to install ninja with Scoop :P
# This is the actual `Build` step
C:\Users\andreatupini\scoop\apps\ninja\current\ninja.exeHopefully this gives us more information on what's going on 😄 Also, I was reading your log a bit more carefully and noticed the error you're getting is when building box2d's tests. We don't really use C:\Users\andreatupini\scoop\shims\cmake.exe --no-warn-unused-cli -DBOX2D_BUILD_UNIT_TESTS=OFF -DCMAKE_EXPORT_COMPILE_COMMANDS:BOOL=TRUE -DCMAKE_BUILD_TYPE:STRING=Debug -DCMAKE_C_COMPILER:FILEPATH=C:\Users\andreatupini\scoop\shims\gcc.exe -DCMAKE_CXX_COMPILER:FILEPATH=C:\Users\andreatupini\scoop\shims\g++.exe -SC:/Workspace/Personal/raylib-cpp-cmake-template -Bc:/Workspace/Personal/raylib-cpp-cmake-template/build -G Ninja |

Hey, update after the weekend :D After reinstalling my home pc and cloning the template from scratch (while installing cmake, gcc, vscode and ninja through scoop) - everything ran without an issue! Today on my work laptop where I was originally getting the errors I noticed I didn't have ninja installed. After installing ninja and switching to gcc 11.2 I no longer get errors and can build successfully! I would recommend adding these 4 things in the readme as a prerequisite - cmake, gcc, ninja and vscode for anyone else wanting to use the template the wonderful template! Thank you so much for taking the time to respond and debug this issue with me! As a side comment, do you think it would be possible to extend the template with support for building to web. not just windows? That way people can use the template to share their game to their friends through itch easily :) (and sadly i'm still fighting my way through learning how cmake/premake work :( ) |

I'm happy to hear it worked! Yeah CMake is really weird when compared with other build tools. I guess it's very capable but this power greatly increases the complexity. And yes I'll make a Wiki on this repo with these instructions so it can be edited by anyone (or anyone can add new instructions for other platforms 🙂 ) Finally, the template already supports building for
