Problems with linking to SDL2 framework on OSX

[lundstroem]

I'm trying to get it to work but every combination of "use_mac_framework" as described in the info results in error. I'm using SDL 2.0.4 and it's located at /Library/Frameworks/SDL2.framework
rustc version is 1.11.0 (9b21dcd6a 2016-08-15)

Cargo.toml:

[package]

name = "hello_sdl2"
version = "0.0.1"
authors = [ "Harry Lundström <palestonesoftware@gmail.com>" ]

[dependencies.sdl2]
features = ["use_mac_framework"]
version = "0.23.0"

cargo clean
cargo build

error: linking with `cc` failed: exit code: 1

cargo test --features use_mac_framework
error: Package hello_sdl2 v0.0.1 (file:///Users/d/Documents/rust-workspace/hello_sdl2) does not have these features: use_mac_framework

Maybe I'm missing something obvious, but any pointers would be helpful.

I see that you closed this issue yet I have the same problem as described here. I hope if you find the solution that you'll share it with me.

[lundstroem]

Hello Jonathan! Unfortunately I never got any response to this issue, and I never found a solution, so I got tired of it and closed it. But now I've re-opened it again. I wish you better luck!

[Cobrand]

try features = ["sdl2-sys/use-mac-framework"]?

[jonathan-quarles]

@lundstroem, Thanks for reopening the issue. @Cobrand, I tried your suggestion but i got this error: error: feature names may not contain slashes: 'sdl2-sys/use-mac-framework'. I wonder if there's a different way to put that.

[Cobrand]

maybe cargo run --features "sdl2/sdl2-sys/use-mac-framework"? I'm pretty sure you can enable a feature of dependency of a dependency, which is probably what you want there (the "use_mac_framework" feature is in sdl2-sys, the one in sdl2 is merely a shortcut).

[jonathan-quarles]

@Cobrand, I just got the same error I did before (error: feature names may not contain slashes: sdl2-sys/use-mac-framework`) after running that. It seems from this issue here, that slashes are a bug on mac (or something).

@jonathan-quarles I also encounted this problem when trying to run a toy project. I was able to make it work with this package configuration:

[package]
name = "platform"
version = "0.1.0"
authors = ["Darkspear7 <blaj.dragos@gmail.com>"]

[dependencies]
platform_traits = { path = "../platform_traits", version = "0.1.0" }
sdl2 = "0.31"

[dependencies.sdl2-sys]
features = ["use_mac_framework"]

[siabard]

It seems very similar with White-Oak/qml-rust#42.

I have a success with my sample project as below.

1. Install SDL2, SDL2_mixer, SDL2_image, SDL2_ttf with package (.dmg)
2. install SDL2_gfx from source. (you may need brew install automake)
3. add build.rs on project root.

fn main() {
    println!("cargo:rustc-link-search=framework=/Library/Frameworks")
}

4. add build to Cargo.toml

[package]
...
build="build.rs"

[dependencies.sdl2]
version = "*"
default-features = false
features = ["use_mac_framework","image","ttf","mixer","gfx"]

[gamecubate]

I think you can close this. I had the same problem 2 days ago but this issue's previous posts led me to the answer, namely (at least in my case):

1. Download and copy the sdl2_ttf framework for macOS to /Library/Frameworks
2. In Cargo.toml, replace

[dependencies]
...
sdl2 = "0.32.2"

with

[dependencies.sdl2]
version = "0.32.2"
default-features = false
features = ["ttf"]

3. cargo clean ; cargo run

[cedeber]

I feel like the build.rs of "rust-sdl2" needs to be:

fn main() {
    #[cfg(any(target_os = "openbsd", target_os = "freebsd"))]
    println!(r"cargo:rustc-link-search=/usr/local/lib");

    #[cfg(all(target_os = "macos", feature = "use_mac_framework"))]
    println!("cargo:rustc-link-search=framework=/Library/Frameworks")
}

Isn't it?

At least without that I can't run cargo test --features use_mac_framework on macOS.
