building on M1 mac

[halpz]

I spent a long time trying to figure out how to build this on my M1 computer, I found a fix, in the makefile there is this section:

# macOS overrides
ifeq ($(HOST_OS),Darwin)
  OSX_BUILD := 1
  # Using MacPorts?
  ifeq ($(shell test -d /opt/local/lib && echo y),y)
    OSX_GCC_VER = $(shell find /opt/local/bin/gcc* | grep -oE '[[:digit:]]+' | sort -n | uniq | tail -1)
    CC := gcc-mp-$(OSX_GCC_VER)
    CXX := g++-mp-$(OSX_GCC_VER)
    CPP := cpp-mp-$(OSX_GCC_VER) -P
    PLATFORM_CFLAGS := -I /opt/local/include
    PLATFORM_LDFLAGS := -L /opt/local/lib
  else
    # Using Homebrew?
    ifeq ($(shell which brew >/dev/null 2>&1 && echo y),y)
      OSX_GCC_VER = $(shell find `brew --prefix`/bin/gcc* | grep -oE '[[:digit:]]+' | sort -n | uniq | tail -1)
      CC := gcc-$(OSX_GCC_VER)
      CXX := g++-$(OSX_GCC_VER)
      CPP := cpp-$(OSX_GCC_VER) -P
      PLATFORM_CFLAGS := -I /usr/local/include
      PLATFORM_LDFLAGS := -L /usr/local/lib
    else
      $(error No suitable macOS toolchain found, have you installed Homebrew?)
    endif
  endif
endif

on M1, the homebrew folder is /opt/homebrew/ so if you change this to:

# macOS overrides
ifeq ($(HOST_OS),Darwin)
  OSX_BUILD := 1
  # Using MacPorts?
  ifeq ($(shell test -d /opt/local/lib && echo y),y)
    OSX_GCC_VER = $(shell find /opt/local/bin/gcc* | grep -oE '[[:digit:]]+' | sort -n | uniq | tail -1)
    CC := gcc-mp-$(OSX_GCC_VER)
    CXX := g++-mp-$(OSX_GCC_VER)
    CPP := cpp-mp-$(OSX_GCC_VER) -P
    PLATFORM_CFLAGS := -I /opt/local/include
    PLATFORM_LDFLAGS := -L /opt/local/lib
  else
    # Using Homebrew?
    ifeq ($(shell which brew >/dev/null 2>&1 && echo y),y)
      OSX_GCC_VER = $(shell find `brew --prefix`/bin/gcc* | grep -oE '[[:digit:]]+' | sort -n | uniq | tail -1)
      CC := gcc-$(OSX_GCC_VER)
      CXX := g++-$(OSX_GCC_VER)
      CPP := cpp-$(OSX_GCC_VER) -P
      PLATFORM_CFLAGS := -I /opt/homebrew/include
      PLATFORM_LDFLAGS := -L /opt/homebrew/lib
    else
      $(error No suitable macOS toolchain found, have you installed Homebrew?)
    endif
  endif
endif

it will now build using gmake

not sure if there is a way to edit the makefile to set the cflags to the brew prefix rather than setting it explicitly

i've made a PR with changes related to this

This works on my 2020 MacBook Air M1 (8gb) with Ventura 13.0.1. Thanks!

Hi folks, I'm working on a version that automatically detects arm64 vs Intel architecture and uses the right flag.

Were you folks able to build a recent version of the tester branch on the M1?
I'm getting a lot of issues with miniaudio including Apple Frameworks and getting lost.

E.g.,

I can easily build this with clang, but then again it would be easier if I could build everything with the same compiler.

[sofakng]

I've submitted a pull request with the changes needed to compile this on macOS: #74

[flatmapthatshit]

@sofakng, I'm a few months late and not sure if something else broken the branch, but while I can compile the tester branch on macOS (both Intel and M1 Apple Silicon), the application fails to start ("Can't start the container"). alpha and tester_rt64alpha are building and running fine. Can you check if the game is still building / working for you?
I'm on macOS Ventura 13.4.1, following the build instructions at https://github.com/flatmapthatshit/Render96ex_macOS#build-instructions btw.

I get an error in the tester branch as well:-

I get an error in the tester branch as well:-.

Do you have the latest gcc version installed with homebrew + all dependencies (see Step 4 from my guide above)? I got the tester branch to compile, but the application errors out during initialisation. The other two branches that I've mentioned are working fine for me.

[flatmapthatshit]

I get an error in the tester branch as well:-.

Also, drop the -j4 for now as they haven't merged my fix to parallel builds to all branches (#84).

[artiqeltt]

how are you supposed to do the tester rt64? i tried with render api rt64 but it is only supported on windows. i used only gmake -j4 and it worked but no raytracing.
