I installed the latest Crystal & raylib on my M1 and cloned the repo.
Some examples seem to work fine, others like shape don't.
Will try to learn the library & test more things later to improve this ticket and try to make it fully work on this platform.
Also, I have an X64 Manjaro Linux to compare.

Crystal 1.3.2 [932f193ae] (2022-01-18)

LLVM: 10.0.0
Default target: aarch64-apple-darwin

Hi

Will it be possible to add support for rres? https://github.com/raysan5/rres

while trying running example i get this error

/usr/lib64/gcc/x86_64-suse-linux/13/../../../../x86_64-suse-linux/bin/ld: cannot find -lminiaudiohelpers (this usually means you need to install the development package for libminiaudiohelpers): No such file or directory
collect2: error: ld returned 1 exit status
Error: execution of command failed with exit status 1: cc "${@}" -o /home/pawel/.cache/crystal/home-pawel-Dokumenty-crystal_proj-learn-lib-raylib-cr-src-raylib-cr-miniaudio_fix-ma_sizes.cr/macro_run -rdynamic -L/usr/lib64/crystal -lminiaudiohelpers -lpcre2-8 -lm -lgc -lpthread -levent -lrt -lpthread -ldl

When running the install.sh script during the final deletion steps:

rm -r raygui
rm -r raylib

Confirmation is needed for every single file:

rm: remove write-protected regular file 'raygui/.git/objects/pack/pack-c928635f2bd28835e7ff73890fec18b8f1b0d2b5.pack'? y

rm: remove write-protected regular file 'raylib/build/examples/CMakeFiles/core_2d_camera_platformer.dir/compiler_depend.internal'? y

etc.

Adding the -f flag would stop the prompting for each file.

I'll open a PR for this change and link it here.

PS: It would probably also be a good idea to add a small cleanup script to remove symlinks and build artifacts if install.sh is run again.

Summary

The font handling within raylib-cr fails, using both v4.2 and v5.0.
I'm on MacOSX.
I have another project in C that uses the raylib apis directly, which works with both 4.2 and 5.

I don't see anything off with the bindings unfortunately, so I wonder if there is something else at play.

Minimal reproducible example

require "raylib-cr"

Raylib.load_font("#{__DIR__}/PTMono.ttf")

Expected

Raylib.load_font doesn't segfault.

Actual

Raylib.load_font segfaults.

I see there has been a recent commit that says "macos support out of the box", and there are several shell scripts in rsrc that start with mac-.
I tried running mac-raylib-build.sh but I get the following error:

CMake Error: The source directory "/Users/avram/Dev/crystal-code/raylib-cr/rsrc/raylib" does not appear to contain CMakeLists.txt.

Are there instructions for building in MacOS? Is it possible to build in MacOS at this point? I have an x86 and an Arm mac, so either works for me.

Currently, the example only renders when the variable lights_dirty is true. However, this makes the example hang since keyboard and mouse functionality are frame-based and refreshed only when a drawing is performed. You'd need to have at least some R.begin_drawing .. R.end_drawing in every loop cycle..

The Rectangle (and all other) struct doesn't have a initialization constructor.

Due to this, initializing Rectangle with argument throws exception.

using

LibRaylib::Rectangle.new(100, 100, 100, 100)

throws the error

In src\sceneMainMenu.cr:22:55

 22 | if LibRayGUI.button( LibRaylib::Rectangle.new(100, 100, 100, 100), "Press me!" )
                                                ^--
Error: wrong number of arguments for 'LibRaylib::Rectangle.new' (given 4, expected 0)

Overloads are:
 - LibRaylib::Rectangle.new()

The way to make this work is to update the properties of Rectangle after it is initialized.
This works;

            LibRaylib.draw_text("Scene Main Menu", 190, 200, 20, LibRaylib::BLACK)
            btnRec = LibRaylib::Rectangle.new
            btnRec.x = 100
            btnRec.y = 100
            btnRec.width = 100
            btnRec.height = 100
            if LibRayGUI.button( btnRec, "Press me!" ) 
                pp "Pressed";
            end

but this is cumbersome to write and deviates from the raylib api where users can create Rectangle with inline parameters like this;

            if LibRayGUI.button( LibRaylib::Rectangle.new(100, 100, 100, 100), "Press me!" )
                pp "Pressed";
            end

Recommendation would be to update the Rectangle struct.
instead of having the Rectangle struct like this;

  struct Rectangle
    x : LibC::Float
    y : LibC::Float
    width : LibC::Float
    height : LibC::Float
  end

we can go for more idiomatic properties with default values and overloaded constructors;

  struct Rectangle
    property x : LibC::Float = 0
    property y : LibC::Float = 0
    property width : LibC::Float = 120
    property height : LibC::Float = 30
    
    def initialize
    end

    def initialize(x, y, width, height)
      @x = x
      @y = y
      @width = width
      @height = height
    end
  end

I ran the rsrc/install.sh script as described in the readme but I get this error:

raygui/src/raygui.c:322:14: fatal error: raylib.h: No such file or directory

      |              ^~~~~~~~~~
compilation terminated.
gcc: error: raygui/raygui.o: No such file or directory

The other examples work fine, but raygui_button doesn't run.

I type in my terminal: crystal run src/raygui_button.cr
I get this error:

hi, i like crystal, raylib seems cool, is it possible to compile it for web? even if with limited features?
thanks

The sole purpose of miniaudiohelpers.c is to determine some struct sizes. On all platforms. the C compiler can calculate struct sizes based on the struct definitions. Therefore, instead of a nearly > 1 MB large miniaudiohelpers library that also fully implements the miniaudio library, one can get an ~ 1 KB large one that is perfectly sufficient.

FIX: remove the #define MINIAUDIO_IMPLEMENTATION in miniaudiohelpers.c

// #define MINIAUDIO_IMPLEMENTATION

#include "miniaudio.h"

size_t MADataConverterSize();
size_t MAContextSize();
size_t MADeviceSize();
size_t MAMutexSize();

size_t MADataConverterSize()
{
  return sizeof(ma_data_converter);
}

size_t MAContextSize()
{
  return sizeof(ma_context);
}

size_t MADeviceSize()
{
  return sizeof(ma_device);
}

size_t MAMutexSize()
{
  return sizeof(ma_mutex);
}

fogshader and rlgl_solar_system give me this error:

Also, sound_test was missing the raylib-cr dependency in it's shard.yml file.
