Compilation error in image crate

[luisvgs]

Hi, I'd like to try the examples that crow provides in its documentation. However, the image-0.23.1 crate during the compilation process, gives me the following error:

error[E0277]: `dyn std::error::Error` cannot be shared between threads safely

For more information about this error, try `rustc --explain E0277`.
error: could not compile `image`.

What can I do in order to solve this issue? My rustc version is 1.43.0-nightly. Thanks in advance.

Hi, I can't reproduce this on the newest nightly, can you try creating a new crate with only image 0.23.1 as a dependency and check if the error persists?

Hi, my apologizes for the late response. I was able to get rid of the image crate error. However, I'm trying to compile both the example from this repository and the example from the documentation from scratch. But the compiler outputs the following:

Here's the full error log. What am I missing? Thank you very much for the help.

The readme example is for the current master branch. If you would like to test the new version, consider adding the following line to your Cargo.toml file:

crow = { git = "https://github.com/lcnr/crow" }

In case this works for you, I will publish it as version 0.6.0.

However, I'm trying to compile both the example from this repository and the example from the documentation from scratch

Can you also please post the code of the failing example from the documentation, and the link to the documentation you are using?
