I have a M1 Macbook pro and after following the instructions on #1736. I downloaded USD repo v22.08 and I'm getting the following error.

ERROR: Failed to run 'cmake --build . --config Release --target install -- -j10'

I have also attached the log.txt file on this issue.

Steps to Reproduce

1. In the terminal I ran python3 build_usd.py /Users/benread/Documents/USD

System Information (OS, Hardware)

Hi @bread24, what version of CMake are you using? I've run into a similar error in the past and it was because I was using an older version of CMake that was built for x86_64. I'd recommend trying a CMake version that ships as a MacOS universal binary -- I'm currently using v3.19.5.

Hi @sunyab

I'm currently using cmake version 3.22.5

I'm downloading 3.24 to see if that makes a difference. Made no difference

[sunyab]

And just to double check, does running arch in your shell give you arm64?

[bread24]

yeah, it shows arm64

[bread24]

I ran python3 build_usd.py /Users/benread/Documents/USD with sudo at the beginning incase it was a weird permission error, but I still get the same error as before

I'm not sure what's going on here. Did you download cmake from the official web site, or was it installed through some other package manager? What do you get if you run

file `which cmake`

[bread24]

I did pip3 install cmake to start off with and after running file `which cmake`

I get /Library/Frameworks/Python.framework/Versions/2.7/bin/cmake: a /Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python script text executable, ASCII text

and

when I use pip install cmake I get the following:
DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support pip 21.0 will remove support for this functionality.
Requirement already satisfied: cmake in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages (3.22.5)

That might be a good clue as to how things are getting confused. Your log shows that the build is versus python3.10, e.g., I see this in a few places -

/Library/Frameworks/Python.framework/Versions/3.10/bin/python3

but which cmake is pointing into python 2.7. It's more than likely that cmake in it's smartness is discovering that it has a sibling python executable in the same bin folder, and things might be going wrong from there.

I would start by uninstalling that cmake, and ensuring that the python you want to use is discoverable in your path, and that the legacy python 2.7 is not discoverable in your path. i.e. ensure this path /Library/Frameworks/Python.framework/Versions/2.7/bin is not in your $PATH at all.

I'd recommend installing cmake from the "official" installer on cmake.org, and DO add the path to the bin within the resulting installation to your $PATH to make it command line accessible.

Hi @bread24, the diagnosis from @meshula should help you out. When we were adding the AS native support we always used Cmake installers from cmake.org, rather than through pip.

[bread24]

Thanks for all the assistance so far but I think I've done something wrong. It's now telling me it can't find ld: symbol(s) not found for architecture arm64

I removed the Python 2.7 path in my ~/.zprofile file and added the directory for cmake-3.23.3 which I downloaded the macOS 10.13 or later version from https://cmake.org/download/

How did you build/install OpenSubdiv? The problem appears to be that it was built for x86_64 but you're building USD for arm64. From the log:

ld: warning: ignoring file /Users/benread/Documents/USD/lib/libosdCPU.dylib, building for macOS-arm64 but attempting to link with file built for macOS-x86_64
ld: warning: ignoring file /Users/benread/Documents/USD/lib/libosdGPU.dylib, building for macOS-arm64 but attempting to link with file built for macOS-x86_64

[bread24]

@dpmacri I'm pretty sure it got build as part of the build_usd.py script. I deleted the old build directory and now it built correctly. Thanks for everyone's help.

Success! To use USD, please ensure that you have:

    The following in your PYTHONPATH environment variable:
    /Users/benread/Documents/USD/lib/python

    The following in your PATH environment variable:
    /Users/benread/Documents/USD/bin

Closing the issue as it's working now
