cgalsimp2 command failed

Hi @fangq

I faced an issue using the meshresample.m with my Mac M1 chip (macOS Monterey 12.4).

Here is the error:

@zhiweigong75, unfortunately iso2mesh does not include any pre-compiled binaries for M1 processors. I expect that not only meshresample.m does not work, many other functions such as meshcheckrepair and s2m/surf2mesh also won't work.

you can, however, compile it yourself if you can set up the building environment. To compile these binaries, you need to run make inside the iso2mesh/tools folder

https://github.com/fangq/iso2mesh/tree/master/tools

you should also use git submodule update --init --remote to download all submodules under that folder. I anticipate setting up the compilation enviroment will take some time. currently, the included Makefile only works on Ubuntu Linux.

@fangq Hi, I am the teammate of @zhiweigong75. I tried two ways to use iso2mesh.

1. I installed iso2mesh by MATLAB Add-Ons, when I called vol2surf, the MATLAB quit without reasons by just killing the process. Here is the error message:

   sakuraxiao@ubuntu:~/Desktop/Statistical-Shape-Modeling/asm-master$ matlab
   MATLAB is selecting SOFTWARE OPENGL rendering.
   Killed

2. I followed the instruction to compile iso2mesh. when I called make clean, it gave me some errors and I had no idea to solve them. Here is the error message:

   sakuraxiao@ubuntu:~/Desktop$ cd iso2mesh/
   sakuraxiao@ubuntu:~/Desktop/iso2mesh$ rm -rf bin/*.mex* bin/*.exe

### Do you have any ideas about these two installation methods? Thank you in advance!

@mikami520, if you run iso2mesh on Ubuntu Linux, you don't need to compile anything. the package should work out-of-box.

are you able to run the built-in examples in iso2mesh/sample folder?
