Static linking of libui

[nshtg]

I looked around but I did not see any option to build a static version of libui and link it directly in our binary. I would prefer this to shipping libui.dll with my exectuable.

Have you looked into this before?

[NoraCodes]

I looked into it briefly in the ui days, before iui became a thing. I would also prefer to have this. If you can figure out how and submit a PR, that would be awesome; if not, I'll look into it when I have time.

Looks like someone already forked iui and added static build capabilities: https://github.com/th0rex/libui-rs
I'm not sure about Mac OS, but it should at least cover Windows and Linux.

@masche842
Hello, do you know how can i enable static building in this repo whe i use cargo-deps?
thx
ps: @th0rex don't have an issues.

@NoraCodes Any preferences for the configuration? (Or do you even want dynamic linking?)

I'd go with two features (static and dynamic). If no flag is enabled, the "platform default" is used. If one of both is enabled, it will be respected and if both are enabled the build script would error. How does that sound to you?

[NoraCodes]

@torkleyy I was hoping to be able to easily test this on a Mac and a Windows machine but haven't been able to set things up as much as I would like. Your approach sounds like a good one, though.

I'm not sure if it works on Windows or macOS, but I made leo60228@e2d8dcf before I saw this issue and it works fine for me.

[barzamin]

@NoraCodes sorry, just saw this. i will test on macOS and Windows if you write the patch :)

@leo60228 I don't know if that's helpful but I tested your fork on Windows 10 and got this error:

[MOZGIII]

See #70. Switching to meson effectively solves the static linkage issues.

[xobs]

Also see #86 which solves the same issue without relying on an external build tool.
