MacOS Support

[marmichalski]

Hi,

I am working on making this work with macOS.

Would you be accepting PR's? If so, my to-do list is as follows:

• Make the source compile on mac (Add macOS support #70)
• Add DPI awareness (currently hardcoded for testing purposes 😛)
• Prepare build env for mac, either with premake or cmake (Add cmake #68)

Hi!
Sure, it would be great to support more operating systems :)

Any news about macos version ??

Hi,

I haven't really found time for it. Making the source compile is quite straightforward. There is no DPI awareness though, but that might not be a problem for you, depends on your configuration. If you have any issues, I can help you either with a patch diff, if I still have the source, or guiding you a bit.

I would love to work on it again, but unfortunately I probably will not have time 😢. If it ever happens, I'll be sure to open a pull request.

@naymapl I have opened a PR with macOS support. To see how you can compile it, check the github workflow yaml. There is no DPI awareness, so if you're using the retina display (scaled), the game window will not be rendered on the whole surface.

@marmichalski thanks for reply. I want to build my own version but I'm not programmer - how to build my own mac version with cmake ? I found this https://github.com/codenamecpp/carnage3d/runs/4388703194?check_suite_focus=true but have no idea how to build it on my own mac. I'm all ready on mac mini m1 12.0.1 macOS but have in home some old mac pro from 2013 and 2015 - Is it run on arm ar I need to build it on Intel machine ? Thank you for any tutorial or code to make it build. Have a nice day Marcin.

Hey, I will be adding the instructions to the readme soon. In short, this should be enough:

• Setup homebrew:
  • https://brew.sh/
• Install dependencies (and cmake):
  • brew install cmake glew glfw3 glm box2d
• Setup and cd into build dir
  • mkdir build && cd build
• Generate build files:
  • cmake .. -DCMAKE_BUILD_TYPE=Release -DWITH_BOX2D=No
• Compile:
  • make -j4 (Where 4 is the threads count you want to use, you can check available with sysctl -n hw.logicalcpu)
• Done. You should have your carnage3d binary compiled

The workflow file I've mentioned is this one: https://github.com/codenamecpp/carnage3d/pull/70/files#diff-8ec8dd620a1a6790f6910af016dd60b1b41485535d15fe2ebb0265593147e57dR58

[marmichalski]

Whoops. Sorry, the parameter is CMAKE_BUILD_TYPE.

And about the error, did you checkout to (or download) the PR branch? Because this include is dfifferent when __APPLE__ is defined (https://github.com/codenamecpp/carnage3d/pull/70/files#diff-e9c682daf5243ad471bbc443ec0b31d50b68080d624259af82010df3a8c8436fR56)

@marmichalski - maybye I'm stupid but When i clone refactore_peds_a branch got this issue:

First i clone branch

git clone --branch refactore_peds_ai https://github.com/codenamecpp/carnage3d.git

then:

cd carnage3d
mkdir build && cd build
cmake .. -DCMAKE_RELEASE_TYPE=Release -DWITH_BOX2D=No
                                                                                                                                     
CMake Error: The source directory "/Users/naymapl/carnage3d" does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.

I try with -CMAKE_BUILD_TYPE but got error is well:

cmake .. -DCMAKE_RELEASE_TYPE=Release -DWITH_BOX2D=No -CMAKE_BUILD_TYPE                                                                                                                      

loading initial cache file MAKE_BUILD_TYPE
CMake Error: Error processing file: /Users/naymapl/carnage3d/build/MAKE_BUILD_TYPE
CMake Error: The source directory "/Users/naymapl/carnage3d" does not appear to contain CMakeLists.txt.

For sure I make something wrong :D

[marmichalski]

git clone --branch refactore_peds_ai https://github.com/codenamecpp/carnage3d.git

This branch has no macOS support. Either clone my fork and checkout to osx branch, or checkout to the PR https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/reviewing-changes-in-pull-requests/checking-out-pull-requests-locally

[codenamecpp]

I didn't update refactore_peds_ai branch yet, it experimental and maybe broken right now, stick with master branch.

Hi - I think is build well. Now i need to organize my old gta files and take a look for it. I let you know but looks like will working. Thank you so much for help and have nice day :D
