Today I experimented with GCC/G++ :(
I was not sure which c++ standards were installed (completely new to c++), so I updated gcc to the latest version with brew (brew install gcc --HEAD) but now it seems that the latest version is unfortunately unstable for my setup.
clang version before: Apple clang version 12.0.0 (clang-1200.0.32.27)
clang version after: Apple clang version 12.0.0 (clang-1200.0.32.27) but with following error:
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
OS: macOS#11.0.1
Does anyone knows how to solve this? I am still able to use g++, only gcc is not working at all, no matter of -std= flag or not. Is installing the latest stable version a proper solution or will this make it worse ;-) ?

You cannot compile C++ code with gcc or clang. You need to use a C++ compiler, such as clang++ or g++.
Check what you are actually running. If you use gcc file.c, at least run:
type gcc
to se what you are running. If it's /bin/something or /usr/bin/something or /Applications/something, it's from Apple. If it's /usr/local/something it's homebrew.
If you are using homebrew, firstly check you are doing everything right by running:
brew doctor
And secondly, make sure your PATH starts with /usr/local/bin which is where homebrew puts its binaries:
export PATH=/usr/local/bin:$PATH

How should I proceed in building it now?
The C++ library dependencies (i.e. Boost/Yaml) you have installed via Homebrew were compiled with clang++. The result is: some symbols resulting from STL interactions when compiling with GCC are missing.
Thus, you have to compile with clang++, e.g. like this:
$ mkdir build
$ CXX=clang++ CC=clang cmake -DCMAKE_BUILD_TYP=Release ..
$ make
Looking at the git repository, the authors even have Mac OS X enabled in their Travis CI configuration:
os:
- linux
- osx
But they also have explicitly excluded GCC builds on Mac OS X:
matrix:
exclude:
- os: osx
compiler: gcc

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [OpenSCAD.app/Contents/MacOS/OpenSCAD] Error 1
Looking at the linker flags, it looks like you might have two different version of Boost installed. Mixing packages from different package managing frameworks makes such issues hard to track down. It could of course be a case of just needing "make clean", but hard to see from only the linker line.
I would recommend using the official build instructions to manage dependencies - those are pretty well maintained on OS X: https://github.com/openscad/openscad#building-for-mac-os-x
Here is my simple test code,
#include <iostream>
int main(){
std::cout << "SAO" << std::endl;
return 0;
}
and compile command below
gcc -o test test.cpp
and I am having a compile error below.

I've tried putting -m32 just in case but still give me error below.

Version of gcc is 4.2 which is installed by XCode "command line tool".
OS is Mac OSX Mountain Lion.
I've tried with gcc 4.7 or clang 3.1 but same error..
Ofcourse, compiling cpp code with gcc will give you error. You should use g++
