Oberseve Error

I feel this error is likely caused by the new Apple M1 Arm64 architecture.

[radj307]

Looking into this.

Edit:

It doesn't seem like its currently possible to compile for ARM64 with github actions: actions/runner-images#5631
Unfortunately that means I don't actually have any way to (legally) compile & distribute for MacOS ARM64 architecture since I don't have access to a machine with that architecture. You can compile it yourself on that machine, however.

I have cloned the repo locally however, I am not too familiar with C++ (and GCC/make) which means I have no real idea how to work around this error.

I CD'd into the repo, and ran make.

The log that you posted mentioned a failure to resolve a symbol from /usr/lib/libstdc++.6.dylib; that likely means that you're missing the libstdc++6 library. Do you have that installed and in the correct location?

Assuming that your device's commandline is similar to debian linux, run this command (or some variation of it) sudo apt-get install libstdc++6 -y from a terminal and try it again.

Follow this guide to build from source: https://github.com/radj307/ARRCON/wiki/Building-from-Source
Judging by the rest of your log though, I'm going to fix the noted compilation errors in case that doesn't work.

[FelixKLG]

running make spits out the following errors:

I deleted my local clone and re-cloned it so this is on the latest commit.

[radj307]

I've implemented a fix for those errors as well in efe4feb; sorry for the delay.

Let me know if any more issues spring up.

[FelixKLG]

Compilation went further than last time however, I still ran into the same issue and then some other ones.

What version of gcc do you have? (Run gcc --version)

[radj307]

Also, can you confirm that the original bug still occurs when libstdc++6 is installed?

[FelixKLG]

GCC/G++:
Apple clang version 14.0.0 (clang-1400.0.29.202)
Target: arm64-apple-darwin22.1.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

I also somewhat under the belief that libstdc++6 is installed. (Due to my XCode install)

[radj307]

You aren't actually using GCC, you're using Apple clang (it doesn't have all of the features from C++20 implemented yet).
ARRCON is written using C++20, so you'll need a compiler that supports that (gcc version 10 or newer).

Here's a guide on installing gcc/g++ with xcode: https://www.cyberciti.biz/faq/howto-apple-mac-os-x-install-gcc-compiler/
That guide is for OS X Mountain Lion but hopefully it'll be transferable.

---

Regarding libstdc++; Apple clang's implementation uses the libc++ standard library instead of the usual libstdc++ provided by gcc.

Installing gcc 10 or newer should fix the problem.
I'm sorry I can't be of more help since I don't own a mac to test this on.

[radj307]

I'm unfamiliar with apple's implementation of make, but that isn't the process that I use to build ARRCON in my build script so I figured I would elaborate on exactly what commands to run:

All of these commands are pulled directly from the CI script that compiles & creates github releases:
https://github.com/radj307/ARRCON/blob/main/.github/workflows/GenerateRelease.yml
The parts that are important for macOS can be summarized as follows:
(Requires cmake v3.22 or newer, ninja, & gcc-10 or newer)

git clone https://github.com/radj307/ARRCON && cd ARRCON
git submodule update --init --recursive
cmake -B "build" -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_COMPILER=g++ -G Ninja
cmake --build "build" ---config Release

The executable is then retrieved from build/ARRCON/ARRCON

[FelixKLG]

I am able to report after installing and linking GCC and G++ manually I was able to compile the code successfully.

A little run-down on the steps I had to take incase anyone else has similar issues:

• Install XCode build tools (xcode-select --install)
• Install Homebrew
• Install gcc via homebrew (brew install gcc)
• Link gcc and g++ to /usr/local/bin/ or add the install path to the PATH env var (If using Apple Silicon link the aarch64 versions)
• Install ninja using brew (brew install ninja)
• Install cmake using brew (brew install cmake)
• Clone repo and run git submodules commands
• Run above cmake commands
• Now it works

Glad to hear that you got it working, and many thanks for the step-by-step guide!
