Symbol not found: ___darwin_check_fd_set_overflow

With Mac OS X 10.14.6, I get the following error with "ManimPango v0.4.0.post1, Python v3.9.7":

Original error: dlopen(/.../lib/python3.9/site-packages/manimpango/cmanimpango.cpython-39-darwin.so, 2): Symbol not found: ___darwin_check_fd_set_overflow
  Referenced from: /.../lib/python3.9/site-packages/manimpango/.dylibs/libX11.6.dylib (which was built for Mac OS X 11.0)
  Expected in: /usr/lib/libSystem.B.dylib
 in /.../lib/python3.9/site-packages/manimpango/.dylibs/libX11.6.dylib

Most likely the key is that libX11.6.dylib (which was built for Mac OS X 11.0), and downgrading to v0.4.0.post0 fixes the issue.

Not sure if there is something to be done here, but is there any strategy for pinning appropriate versions in a platform dependent way, either with Conda, poetry, or pip?

So something is wrong with the v0.4.0.post1 version and not v0.4.0.post0? I'll check the build logs to see if there is any issue.

[naveen521kk]

Hmm, yeah checking build log something is broken

  /usr/local/Cellar/libx11/1.7.3.1/lib/libX11-xcb.1.dylib
  /usr/local/Cellar/libx11/1.7.3.1/lib/libX11.6.dylib
  /usr/local/Cellar/libxau/1.0.9/lib/libXau.6.dylib
  /usr/local/Cellar/libxcb/1.14_1/lib/libxcb-render.0.0.0.dylib
  /usr/local/Cellar/libxcb/1.14_1/lib/libxcb-shm.0.0.0.dylib
  /usr/local/Cellar/libxcb/1.14_1/lib/libxcb.1.1.0.dylib
  /usr/local/Cellar/libxdmcp/1.1.3/lib/libXdmcp.6.dylib

These libs weren't(and shouldn't be) included in previous release. Thanks for reporting. I'll fix soon.

[naveen521kk]

This was because of a new version of meson, which added support for finding Xlib, so I have pinned the previous version for now.

@mforbes can you test the wheels from here from CI run of #74?

[mforbes]

@naveen521kk Works with python 3.9 (I can generate some animations - did not run a full test suite though). It basically works with 3.7, 3.8, and 3.10 (I can import manim which typically raises the error, but my dependences make it hard to test full functionality quickly.)

Let me know if you want me to try to run a full test suite. I have not done that before, but probably could.

Thanks!

P.S. (Will this be released as post2 eventually?)

Let me know if you want me to try to run a full test suite. I have not done that before, but probably could.

I don't think it's needed, just running import should be enough.

Will this be released as post2 eventually?

Yup.

[naveen521kk]

The new release(.post2) fixes this, right?

[mforbes]

Works for me. Thanks!
