puremourning · 2020-09-27T15:07:25Z

When did this start happeneing ? was it immediately after installing 10.15.7 ?

You need to help us repro/unsdersand this issue as watchdog has been successfully building on Mac for ages and works in our CI. This suggests it's a unique problem in your environment. or something that's broken with an Xcode upgrade.

sillybun · 2020-09-27T15:17:08Z

yes, last month, I successfully built ycm on macOS. Do you have any suggestions about how can I solve the problem?

sillybun · 2020-09-27T15:19:58Z

and my python version is: Python 3.8.2

puremourning · 2020-09-27T15:27:38Z

Did you recently upgrade Xcode? What other things have you recently done on your system that might affect this.

This error is coming from your system headers and clearly nothing to do with YCM code. It's actually the watchdog python module that's filling to build.

puremourning · 2020-09-27T15:30:25Z

Ah could be an Xcode-12 things ? https://developer.apple.com/documentation/xcode/building_a_universal_macos_binary

seems xcodebuild is trying to build an arm target pointlessly for watchdog.

puremourning · 2020-09-27T15:36:36Z

I'm going to update to Xcode 12 and see if I can repro.

You may be able to make it work by using the command line tools, rather than Xcode (see man pages for xcode-select)

puremourning · 2020-09-27T16:31:59Z

I can't repro.

bstaletic · 2020-09-27T18:49:12Z

A workaround would be temporarily getting rid of setup tools, so that watchdog doesn't get compiled.

YCM still needs a working watchdog, but it should use a different API.

The downside is worse watchdog performance.

sillybun · 2020-09-28T15:01:11Z

I have solved the problem by using python3 downloaded from the official website instead of python from brew.

sillybun · 2020-09-28T15:02:58Z

@puremourning @bstaletic thanks for your kind help

ddeville · 2020-09-29T05:30:51Z

Getting the same errors here after updating to Xcode 12. Also tried switching to the command line tools but same issue (which is not surprising since it’s using the same SDK and project settings anyway).

As noted above, this line implies that an arm64 slice is being built here:

xcrun -sdk macosx clang -Wno-unused-result -Wsign-compare -Wunreachable-code -fno-common -dynamic -DNDEBUG -g -fwrapv -O3 -Wall -iwithsysroot/System/Library/Frameworks/System.framework/PrivateHeaders -iwithsysroot/Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.8/Headers -arch arm64 -arch x86_64 -DWATCHDOG_VERSION_STRING="0.10.2" -DWATCHDOG_VERSION_MAJOR=0 -DWATCHDOG_VERSION_MINOR=10 -DWATCHDOG_VERSION_BUILD=2 -I/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/include/python3.8 -c src/watchdog_fsevents.c -o /Users/damien/.vim-plug-plugins/YouCompleteMe/third_party/ycmd/third_party/watchdog_deps/watchdog/build/3/temp.macosx-10.14.6-x86_64-3.8/src/watchdog_fsevents.o -std=c99 -pedantic -Wall -Wextra -fPIC -Wno-nullability-completeness -Wno-nullability-extension -Wno-newline-eof -Wno-error=unused-command-line-argument

Looks like the setup script for Watchdog FSEvents potentially needs to be altered.
They have an opened issue for this same issue but there doesn’t seem to be much activity on the repo in the last few months.

puremourning · 2020-09-29T06:52:42Z

@ddeville thanks for the info. Now I’m confused why I can’t reproduce. I’ll try harder.

ddeville · 2020-09-29T16:49:17Z

Hey @puremourning I’ve added more info in gorakhargosh/watchdog#689.

I believe the problem happens when using the Python (3.8.2) that ships with Xcode. /usr/bin/python is a simple trampoline to this version. I think Apple’s fork might be setting up the archs to support arm64 in a way that messes up with some extensions.
The workaround here is to install the latest Python version from python.org (or brew or pyenv or whatever).

puremourning · 2020-10-02T21:24:10Z

Thanks

So this is a Xcode python bug and the solution is to ask Apple to fix it or use upstream or homebrew python.

rwmitchell · 2020-10-15T16:37:44Z

I'm having the exact same issue, that's how I got here.

I'm in the processes of migrating to a newer MBP with 10.15.7. Installed python 3.9 from python.org, creating a symlink to it in /usr/local/bin. Once I got rid of an PYTHONPATH variable, everything seemed to finally work....until this. Just like the OP, I'm getting

Did I miss reading the solution??

lockerfish · 2020-10-15T16:55:32Z

I experienced this issue with NeoVim and UltiSnips. Solved by running the following commands:

:echo has('python3') returned 0 even though python3 -m pip install --user --upgrade pynvim didn't show errors.

brew upgrade python3 showed I was in the latest version

running brew link --overwrite python@3.8 fixed the issue for me.

:echo has('python3') returned 1 now and UltiSnips did not break with errors.

Writing it here to hopefully help someone running into the same issue.

rwmitchell · 2020-10-15T17:22:10Z

I don't do brew, wonder what that actually changed?

By changing the xcrun command by removing arm64 to:

xcrun -sdk macosx clang -Wno-unused-result -Wsign-compare -Wunreachable-code -fno-common -dynamic -DNDEBUG -g -fwrapv -O3 -Wall -iwithsysroot/System/Library/Frameworks/System.framework/PrivateHeaders -iwithsysroot/Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.8/Headers -arch x86_64 -DWATCHDOG_VERSION_STRING="10.2" -DWATCHDOG_VERSION_MAJOR=0 -DWATCHDOG_VERSION_MINOR=10 -DWATCHDOG_VERSION_BUILD=2 -I/Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.8/include/python3.8 -c src/watchdog_fsevents.c -o /Users/foo/.vim/bundle/YouCompleteMe/third_party/ycmd/third_party/watchdog_deps/watchdog/build/3/temp.macosx-10.14.6-x86_64-3.8/src/watchdog_fsevents.o -std=c99 -pedantic -Wall -Wextra -fPIC -Wno-nullability-completeness -Wno-nullability-extension -Wno-newline-eof -Wno-error=unused-command-line-argument

that command completes without any errors, but the original command gets rerun when doing:
python3 ./install.py --clang-completer in the YouCompleteMe git directory. and I don't see what is generating it.

Certainly that brew command is just changing a symlink somewhere?

ddeville · 2020-10-15T17:36:07Z

I think this command is actually run by Python itself and the fact that it includes the arm64 slices makes me think that it's using Apple system's Python.

Can you check your path (and/or do which python3) and make sure that it's in fact picking the one you've installed from python.org and symlinked in /usr/local/bin?

rwmitchell · 2020-10-15T17:53:24Z

I have my own script to show all locations of an executable in my path with the current one highlighted in green. I suspected the coloring fill fail here, so i tried including an image above. anyway, where are both:

l           9 2020-10-15 09:29:58 /Library/Frameworks/Python.framework/Versions/3.9/bin/python
l          75 2019-12-05 06:24:41 /usr/bin/python
l          61 2020-10-15 10:47:58 /usr/local/bin/python

❯ which python
/usr/local/bin/python

❯ python --version
Python 3.9.0

and it still fails.

rwmitchell · 2020-10-15T17:58:48Z

I should have paid more attention to your question:

sigh So focused on python, overlooked what python3 was doing. Fixed pathing to find 3.9 first and all is better.
