# \*-win7-windows-gnu
2+
3+
**Tier: 3**
4+
5+
Windows targets continuing support of Windows 7.
6+
7+
## Target maintainers
8+

- @tbu-
10+
11+
## Requirements
12+
13+
This target supports all of core, alloc, std and test. Host
14+
tools may also work, though those are not currently tested.
15+
16+
Those targets follow Windows calling convention for extern "C".
17+
18+
Like any other Windows target, the created binaries are in PE format.
19+
20+
## Building the target
21+
22+
You can build Rust with support for the targets by adding it to the target list in config.toml:
23+
24+
```toml
25+
[build]
26+
build-stage = 1
27+
target = ["x86_64-win7-windows-gnu"]
28+
```
29+
30+
## Building Rust programs
31+
32+
Rust does not ship pre-compiled artifacts for this target. To compile for this
33+
target, you will either need to build Rust with the target enabled (see
34+
"Building the target" above), or build your own copy by using `build-std` or
35+
similar.
36+
37+
## Testing
38+
39+
Created binaries work fine on Windows or Wine using native hardware. Remote
40+
testing is possible using the `remote-test-server` described [here](https://rustc-dev-guide.rust-lang.org/tests/running.html#running-tests-on-a-remote-machine).
41+
42+
## Cross-compilation toolchains and C code
43+
44+
Compatible C code can be built with gcc's `{i686,x86_64}-w64-mingw32-gcc`.
