Cannot build. Failed to select a version of imgui-sys

[MarcosDanielTorres]

Description

Hey guys, first of all, thank you for your work.
As this is the first time I'm using imgui maybe it's an experience-related problem. But when trying to use imgui-wgpu I'm having trouble building the project. But maybe the version of the crates I'm using are not right.

This is how my cargo.toml looks like:
(the cargo.toml of the examples uses version 0.11 for imgui and imgui-winit-support)

wgpu = "0.15"
winit = "0.27.5"

imgui-wgpu = "0.22.0"
imgui = "0.11"
imgui-winit-support = "0.11"

Problem

error: failed to select a version for `imgui-sys`.
    ... required by package `imgui v0.10.0`
    ... which satisfies dependency `imgui = "^0.10"` of package `imgui-wgpu v0.22.0`
    ... which satisfies dependency `imgui-wgpu = "^0.22.0"` of package `wgpu_playground v0.1.0 (C:\Users\_\projects\cg\own\wgpu_playground)`
versions that meet the requirements `^0.10.0` are: 0.10.0

the package `imgui-sys` links to the native library `imgui`, but it conflicts with a previous package which links to `imgui` as well:
package `imgui-sys v0.11.0`
    ... which satisfies dependency `imgui-sys = "^0.11.0"` of package `imgui v0.11.0`
    ... which satisfies dependency `imgui = "^0.11.0"` of package `imgui-winit-support v0.11.0`
    ... which satisfies dependency `imgui-winit-support = "^0.11"` of package `wgpu_playground v0.1.0 (C:\Users\_\projects\cg\own\wgpu_playground)`
Only one package in the dependency graph may specify the same links value. This helps ensure that only one copy of a native library is linked in the final binary. Try to adjust your dependencies so that only one package uses the links ='imgui-sys' value. For more information, see https://doc.rust-lang.org/cargo/reference/resolver.html#links.

I have the same issue!

Hey Mark, I fixed it changing the versions of imgui and imgui-winit-support to 0.10 instead of 0.11
What confused me was that the examples had the 0.11 versions of those crates

I found that I had to start using the git HEAD version of imgui-wgpu, after upgrading imgui to 0.11.0 and wgpu to 0.16.0, as imgui-wgpu 0.22.0 (the latest version of crates.io) still uses imgui 0.10.0...

I have the same issue. It would be helpful for the author to provide an example with a clean cargo file that uses this actual crate.

[trojanfoe]

I’ve dumped imgui now; it’s too much aggro.

I do not actively use this crate anymore. PRs for version bumps are welcome and I'll gladly merge and release. But considering I do not follow the release schedule of dependents it does not make much sense for me to make those changes.
