Support for Windows?

[Mereep]

Hello,

I am trying my very first steps in Rust. Actually Peroxide is my first dependency I tried to include into my project. So, it may be a beginners mistake, but I really cannot make it work.

Here is what I did:

• Included the dependency like:

[dependencies.peroxide]
version = "0.21"
default-features = false
features = ["dataframe"]

• Compiled (without problems). Cargo build fails with:

= note: LINK : fatal error LNK1181: cannot open input file 'netcdf.lib'

• Downloaded+Installed netcdf from

https://www.unidata.ucar.edu/software/netcdf/docs/winbin.html

• Built again, same problem
• Added lib folder of netcdf manually to PATH
• Double checked its availability

> where netcdf.lib
>> C:\Program Files\netCDF 4.7.4\lib\netcdf.lib

• Cleaned the build (cargo clean)
• built from scratch
• Dependencies built again fine, particularly:

Compiling netcdf v0.2.0

• Linker still fails on

error: linking with `link.exe` failed: exit code: 1181

• Notice the double quoted entries at the end of the command like "netcdf.lib" "netcdf.lib" (which also appear for some reason twice?!)
  • At this point there are too many questions: What is generating the link command?
  • is it supposed to find the paths correctly alone?
  • why some entries are duplicated?
  • am I supposed to install the libs by hand at all?
  • if yes: how am I expected to exactly know which versions those should be?
  • how can I make cargo actually recognize them?
• Too many questions -> Gave up and came here.

Versions:

cargo --version

rustc --version

Hello, @Mereep
I have not tried to use peroxide in Windows 10 before.
So I will try to test on Windows 10, and will comment about it.

[Axect]

@Mereep I tested and succeeded.

This problem is derived from linker path.
I don't know the global and permanent solution but there is a project-level solution.

• Make build.rs in your project directory and add linker path for netcdf

fn main() {
    println!(r"cargo:rustc-link-search=C:\Program Files\netCDF 4.7.4\lib")
}

• Modify your Cargo.toml

[package]
name = "net_test"
version = "0.1.0"
authors = ["John Doe"]
edition = "2018"
build = "build.rs"

[dependencies]
peroxide = { version="*", features=["dataframe"] }

Then you can build it and run it!

Hi,

thanks this works :)

Still, I wonder why cargo does not allow to do such a thing in tha toml-File. Is there a reason the process works under Linux but not under Windows?

[Axect]

@Mereep
Maybe there is the way using Cargo.toml. But I don't know.

My personal reason that works under linux is convenience and performance.

[magnusuMET]

This is a bug in the netcdf crate, where we do not add the correct path to the linker search path. I hope this will be a non-problem in the future when netcdf can be built statically (see georust/netcdf#56 for progress on this).
