Building using mingw

[RazrFalcon]

Does it supported?

Currently I'm getting:

ld: cannot find -ld2d1

Windows 7 32bit

[gabdube]

I'm testing right now. It should be possible.

This error is raised because the direct2D library cannot be found. I've just learned that Direct2D was first introduced in Windows 8 but it was then backported to Windows 7. This might solve your problem: https://msdn.microsoft.com/en-us/library/windows/desktop/jj863687(v=vs.85).aspx

Hrmm, I will have to feature gate the canvas control...

Edit: It seems mingw is the cause of the problem, I'll look into it to see if I can fix this.

I'm getting this in Windows 10, too.

@eugene-bulkin

I know... Somehow mingw build cannot link/access d2d1.lib which is used by the canvas control.

[eugene-bulkin]

@gabdube Just wanted to clarify that it's present in a later version too, that's all!

[gabdube]

update. After feature gating the canvas, I've found that there was another error which was already referenced here (#29).

Currently this is my top priority. Hopefully, I'll be able to fix both issue or find a workaround.. otherwise NWG might be locked to msvc toolchains and that would suck.

Edit: Mingw do not define GetWindowSubclass in comctl32.lib

It looks like an executable needs to have a manifest to be able to use version 6 of comctl32 (see MSDN). Doing this cleanly is blocked on rust-lang/rfcs#721, though.

Cargo-update is using this workaround to embed a manifest, but I don't know if this is a good solution for NWG as a library.

Finally got myself to work on a workaround and it looks like it works (at least on my machine). If any of you are still interested just pull the dev branch and run cargo run --example showcase. :)

This should also allow cross-compilation from linux.

[RazrFalcon]

Great. Work for me, except simple_canvas.rs.

[gabdube]

Oh yeah, the canvas control is now behind the canvas feature because it requires d2d1.lib which is not included with the gnu version of rust.

if you want to run the example,
Download libd2d1.a from https://github.com/retep998/winapi-rs/blob/dev/i686/lib/libd2d1.a
Copy it in your rust installation lib path. ie: toolchains\stable-i686-pc-windows-gnu\lib\rustlib\i686-pc-windows-gnu\lib
then run: cargo run --example simple_canvas --features="canvas"

and it should work

edit: the lib link above is for 32bits, this one is for x64: https://github.com/retep998/winapi-rs/blob/dev/x86_64/lib/libd2d1.a
