Segmentation fault on macOS Big Sur with M1

[fynnlyte]

I've been trying to get gtimelog running on macOS (M1). After installing needed libraries via brew and using Python 3.9.4, I'm getting the following error on startup:

Unable to configure translations: no locale.bindtextdomain()
Created /Users/me/.local/share/gtimelog
Settings from /Users/me/.config/gtimelog/gtimelogrc migrated to GSettings (org.gtimelog)
[1]    52861 segmentation fault  gtimelog

I've installed these packages via brew:

pygobject3
gtk+3
py3cairo
pango
gobject-introspection
libsoup

As suggested in this issue, I've made the library path available via:

export DYLD_LIBRARY_PATH=/opt/homebrew/lib

Did anyone have more success?

[carlocab]

In case someone else reads this issue without also reading the linked one (Homebrew/homebrew-core#75020), I strongly recommend against setting DYLD_LIBRARY_PATH for general usage. It's a debugging tool at best, and encountering segfaults when this is set is not surprising. (Not to say that this is the cause of the segfault here.)

[fynnlyte]

Without setting the DYLD_LIBRARY_PATH, I'm getting this assertion error:

Previous assertions pass, but it fails for FontDescription.

If I'm setting the DYLD_LIBRARY_PATH and running gtimelog from source, I'm getting this error first:

Typelib files for Secret-1 are not available.

If you're on Ubuntu or another Debian-like distribution, please install
them with

    sudo apt install gir1.2-secret-1

So I did brew install libsecret and only got this error on startup:

Unable to configure translations: no locale.bindtextdomain()

But then still the segfault. I guess this is rather an upstream issue/ M1-specific problem.

[mgedmin]

I don't have a Mac (and I never had one), so I'm afraid I'm not going to be much help here.

I wonder if setting PYTHONFAULTHANDLER=1 would shed any light on the segfault?

The no locale.bindtextdomain() error is not critical; it may mean that some of the translations won't work, but the app itself should run. (I also wonder if brew install gettext or something might make that error go away?)

[fynnlyte]

I also wonder if brew install gettext or something might make that error go away?

gettext was already installed as a dependency. But perhaps a changed default path also causes an issue here.

I wonder if setting PYTHONFAULTHANDLER=1 would shed any light on the segfault?

Not much:

No worries, I'll retry once in a while and let you know when it works. In the error Report, I get the following. Doesn't look like anything that gtimelog can do about, rather like an issue the gi bindings.

[mgedmin]

Yeah, that looks like either a bug in pygobject, or a library mismatch between python, pygobject and/or glib.

[mgedmin]

I remember seeing a native MacOS app inspired by gtimelog, but what was it called... ?

[DocEpsilon]

@LyteFM can you try setting DYLD_FALLBACK_LIBRARY_PATH=/opt/homebrew/lib?

Note: It's fallback, not DYLD_LIBRARY_PATH!

[fynnlyte]

Hi,

I've tried it with the fallback path instead. Same segfault error. I'm now on macOS 11.3.1. https://gitlab.gnome.org/GNOME/pygobject/-/issues/417 might be related to the problem of missing libs, but that seems to be solved by the fallback path.

[DocEpsilon]

As this issue here is closed, I believe you want to follow wether this PR gets merged.
