Cannot compile on OS X

[ArsalanDotMe]

I'm running the latest OSX with CUDA and cudnn installed.

I have to use the git repo of collenchyma as dependency because the latest version includes a fix for linking OpenCL on OS X. Rest of the configuration is default.

When I run cargo build, I get the following errors:

What could be wrong?

[hobofan]

The problem has to do with the way Cargo compiles dependencies, and isn't too obvious.

I am guessing that you replaced the collenchyma dependency in Cargo.toml with a link to the Github repository? This actually results in two different collenchyma libraries to be built, since Leaf still depends on the collenchyma version from crates.io.

You can override the collenchyma dependency for project-wide. For this you have to clone collenchyma locally and add a .cargo/config file to your project root containing:

path = ["/path/to/your/collenchyma/clone"]

See the Cargo documentation for more reference.

There is also an issue to make those overrides not require a clone of the repository, making them more painless: rust-lang/cargo#1481

I hope that gets it working for you :)

Thanks for the tip. It does seem to have solved that problem but unfortunately now, I'm running into another error I can't make sense of. Have a look.
