qt - 无法为 qmlrs 运行自定义构建命令

Question

我正在尝试使用 qmlrs Rust 绑定(bind)到 Qt，但我无法编译。我已经安装了所有依赖项。

• 使用rust 1.9.0
• cargo 0.10.0-每晚(10ddd7d 2016-04-08)

cargo 构建日志:

error: failed to run custom build command for `qmlrs v0.1.1`

您应该安装提供该文件的 Qt 的 -dev 包。 Here's a hint如何使用 apt-file 找到相关包(如果您使用的是 Debian 衍生发行版)。在您的情况下，错误消息显示也许你应该添加包含 Qt5Qml.pc 的目录，所以:

$ sudo apt install apt-file && sudo apt update
$ apt-file search Qt5Qml.pc
>>> qtdeclarative5-dev: /usr/lib/x86_64-linux-gnu/pkgconfig/Qt5Qml.pc
$ sudo apt install qtdeclarative5-dev
