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

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.,

gcc-12 -c -O2 -I /opt/homebrew/include -I include -I build/us_pc -I build/us_pc/include -I src -I . -DDYNOS -DRAPI_GL=1 -DWAPI_SDL2=1 -DAAPI_SDL2=1 -DCAPI_SDL2=1 -I`sdl2-config --prefix`/include -DHAVE_SDL2=1 `sdl2-config --cflags` -DVERSION_US -D_LANGUAGE_C -DGIT_HASH="\"b86a6827\"" -DNON_MATCHING -DAVOID_UB -DOSX_BUILD -DF3DEX_GBI_2E -fno-strict-aliasing -fwrapv -DEXT_OPTIONS_MENU -DFS_BASEDIR="\"res\"" -o build/us_pc/levels/wmotr/geo.o levels/wmotr/geo.c

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

I've submitted a pull request with the changes needed to compile this on macOS: https://github.com/Render96/Render96ex/pull/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.
