What is the contents of the E:\rust\cargo\lib\azul-dll-0.1.0\target\release directory? Is there an azul.dll file in there?

[fschutt]

Also, the hello_world example isn't yet updated for the new API, the only two working examples right now are public and opengl.

[fschutt]

os error 5 means that the dll file exists, but access to it is denied, due to permission problems. If you are on an Administrator account, this should not happen. Try applying this guide to your E:\rust\cargo directory: https://appuals.com/fix-error-5-access-denied-windows-10/

[fschutt]

Sorry, this error was due to a typo in the macro:

include_bytes!(concat!(env!("CARGO_HOME"), "/lib/", "azul-dll-", env!("CARGO_PKG_VERSION", "/target/release/azul.dll")));

should have been:

include_bytes!(concat!(env!("CARGO_HOME"), "/lib/", "azul-dll-", env!("CARGO_PKG_VERSION"), "/target/release/azul.dll"));
                                                                                         ^

... which led cargo to try and include an entire (non-existent) directory instead of just one file.

This is fixed in 6e5cdb5, please adjust your Cargo.toml and try again. You do not need to run cargo install azul-dll, because this was just a typo in the path:

azul = { git = "https://github.com/maps4print/azul", rev = "6e5cdb597c478cd664bd2695146e442fbcb5230f" }

I thought when run this shell cargo install --path azul-dll ,the dll well right there ，
I have copy dll to cargo\lib\ ,
now，it seems i have copy to the wrong path

Thank you for your patience!!

[fschutt]

Does it work now?

[lable-bit]

Does it work now?
i do not kown ,why it does not works , azul.dll is just in the right place ,

new a project
just like this dependencies azul = { git = "https://github.com/maps4print/azul", rev = "6e5cdb597c478cd664bd2695146e442fbcb5230f" }
the same error
i have try fix with Absolute path include_bytes!("E:/rust/azul/target/release/azul.dll") ,it works

but it give me another error
my code git clone form branch wip

As I said, cargo run --example hello_world does not work at the moment.

Only cargo run --example public and cargo run --example opengl do.

I don't know why the installation isn't working smoothly - the dll file should be in your .cargo directory, usually this is C:\\Users\[user]\.cargo, not E:\rust\

[lable-bit]

all right ，public and opengl works well ，thanks !!!
some where give me advise to set environment variable
I want to do a Windows application to parse JSON， hope everything goes well
happy code ！
