添加了rustflags后，运行示例代码还是出现链接错误。 #153

Closed yomiko451 closed 9 months ago

yomiko451 commented 9 months ago

一开始运行示例代码出现链接错误后，我看到issues里也有类似情况，需要在cargo.toml里添加rustflag链接需要的库，但是我按照说明修改后，依然不起作用，还是同样的错误。我试着自己捣鼓了一天还是无果，只能来这里问了，希望大佬能解答一下。

这是我的cargo.toml文件内容：

name = "mpp"
version = "0.1.0"
edition = "2021"

[target.x86_64-pc-windows-msvc]
rustflags = [
    "-C", "link-arg=Mfplat.lib",
    "-C", "link-arg=Strmiids.lib",
    "-C", "link-arg=Mfuuid.lib",
    "-C", "link-arg=Bcrypt.lib",
    "-C", "link-arg=Secur32.lib",
    "-C", "link-arg=Ole32.lib",
    "-C", "link-arg=User32.lib"
]

[package.metadata.vcpkg]
dependencies = ["ffmpeg[x264,vpx]:x64-windows-static-md"]
git = "https://github.com/microsoft/vcpkg"
rev = "4a600e9"

[dependencies]
rsmpeg = "0.14.1"

但是还是出现了链接错误：

warning: unused manifest key: target.x86_64-pc-windows-msvc.rustflags
   Compiling mpp v0.1.0 (C:\code\mpp)
error: linking with `link.exe` failed: exit code: 1120

原来如此，还是学的少了，多谢多谢！
