我应该什么时候安装“*-dev”包？

  • 772

有时，apt-cache 会提供“-dev”包，例如：

libdianewcanvas2     - a gtk+2 vectorial canvas with extra features
libdianewcanvas2-dev - a gtk+2 vectorial canvas with extra features

我想知道什么时候应该安装“*-dev”包？libdianewcanvas2 和 libdianewcanvas2-dev 有什么区别？

    让我们比较apt show PACKAGENAME两个包的输出。我没有在这里显示完整的输出，只是一些相关的部分：

    $ apt show libdianewcanvas2 libdianewcanvas2-dev

Package: libdianewcanvas2
Version: 0.6.10-5.4
[...]
Description: a gtk+2 vectorial canvas with extra features
 Dia-newcanvas is a gtk+2 vectorial widget that has got extra features as

Package: libdianewcanvas2-dev
Version: 0.6.10-5.4

 This package contains the header files and static library needed for
 development of programs using dia-newcanvas.

    这里的区别**This package contains the header files and static library needed for development of programs using dia-newcanvas.**实际上是大多数*-dev包的描述。

    总而言之，您通常只需要*-dev包来基于包提供的库开发自己的应用程序。除此之外，我看不到您想要手动安装一个的用例。当然，您安装的某些其他软件包也可能总是将*-dev软件包作为依赖项，因此它会自动安装。
