Same thing here, to fix (not tested thought) just do what the compiler says: Line 230: bytes_per_row: Some(width_nonzero), Line 231: rows_per_image: Some(height_nonzero),

Kofituo commented 1 year ago

Facing this issue as well

ahirner commented 1 year ago

I think this can be closed after https://github.com/l1npengtul/nokhwa/pull/142 and thus is duplicated by #141.

mangoleaf commented 1 year ago

I agree that it can be closed, but it would also be nice if 0.10.5 crate was released so people don't have to pull directly from the git repo for the fix

Kofituo commented 1 year ago

@mangoleaf @ahirner Actually, this issue still stands even to the date. I'm using M1 mac if that helps.

mangoleaf commented 11 months ago

@Kofituo The fix was merged in #142, but the rust crate was never released since. This worked for me when I checked out the latest code instead of trying to get the crate via crates.io. I am also on an M1 mac.

Kofituo commented 11 months ago

@mangoleaf @ahirner That's surprising. Here's my full project https://github.com/Kofituo/sample_gui/blob/master

Here's the full list of errors I'm facing. They're mostly syntax errors, among others:

@Kofituo I was facing the same issue on mac m1, but using the pull #142, commit "8987af8", It compiles fine on my machine.
