Question

我正在关注this tutorial使用cairo-rs为图像绘制一些东西。当我运行我的代码时，我得到一个非常冗长的错误。重要的一点似乎是：

linking with "cc" failed: exit code: 1

和

ld: library not found for -lgobject-2.0 
clang: error: linker command failed with exit code 1

我通过MacPorts安装了Cairo，所以这应该不是问题。我从教程中复制了Cargo.toml文件，除了最新的软件包：

[dependencies]
png = "0.12.0"
cairo-rs = {version = "0.4.1", features = ["png"]}

我也尝试过本教程中列出的版本，但是我得到了同样的错误。

Rust issue 18610似乎有类似的错误，建议安装libc-dev。我不知道那是什么或为什么会解决任何问题。

我在某个地方看到它可能是一个命名冲突，所以我改变了我的项目的名称，以免冲突，但它没有帮助。

详细

我正在使用Rust，我甚至重新安装了它。
MacOS High Sierra，版本10.13.3（17D47）

Answer 1

您需要安装glib和cairo的正确开发库。

如果您的操作系统与Debian相关，请输入apt install libglib2.0-dev。

如果您使用的是macOS和Homebrew，请键入brew install glib，然后brew install cairo。

无法使用cairo-rs链接程序：“与`cc`链接失败”和“找不到-lgobject-2.0的库”
