Taichi: OSX compilation fails

[r03ert0]

Hello!
I followed the OSX compilation instructions (wget + python3 install.py), and it fails like this:

-- Build files have been written to: /Applications/_Sci/taichi/build

Any idea? Thanks in advance!

I tried again in a clean mac. I freshly installed the xcode CLI tools, anaconda with python 3.7, brew, wget and cmake. Now the compilation goes up to 100%, but fails nevertheless. This is the end of the log:

I was checking the Mac configuration in Travis CI, but I can't figure out what to change.
But maybe Travis CI could be used to produce a binary distribution? This url shows how to do it: https://docs.travis-ci.com/user/deployment/releases/

I join the MacOS crowd, I have the same issue as @r03ert0, macos 10.14.4, anaconda, python3.7, builds fine, but then crashes with the Segmentation fault.

[brejchajan]

It seems that there is some problem with Anaconda python, which is weird. I tried building with python 3.7 from Homebrew and now I am able to import taichi without the segfault. However, another exception occurs when I try to run any example (for instance simulation/3d/mgpcg_smoke_3d.py).

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'NSWindow drag regions should only be invalidated on the Main Thread!'

For complete log see the attached file taichi_crash.txt. Any help is much appreciated!

P.S. I tried also on Windows, and everything seems to be working there (there was just hardcoded version 3.6 of python library in CMake files, which I needed to change).

I encount similar problem as @brejchajan on OSX.

1. Anaconda python will crash when compiling.
2. I tried different c++ compilers (clang 10, gcc 5, gcc 7), and different python versions (3.5, 3.6, 3.7), but all of them failed. (with different errors)

Could someone successfully run examples give the available versions of c++ compiler and python?

[AntiInsect]

I kind of get lucky on the same problem described above.
In the first place, I am also trapped by the Anaconda python, then I change to brew-installed python. i.e. brew install python@3. On my mac, the path is something like /usr/local/Cellar/python/3.7.3/bin/python3.7.
And also, I use the gcc-9 and it works fine (I haven't tried clang though)
