问题描述

什么是devel包像libgtk + -devel或中的python-DEVEL等实用工具?难道它们所包含的库源?它是如何不同于非devel包状libgtk +?

What is the utility of devel packages like "libgtk+-devel" or "python-devel" etc.? Do they contain source of the library? How is it different from non-devel packages like libgtk+?

推荐答案

* - DEVEL 包(通常称为 * - 开发基于Debian的发行版),通常所有必要的编译code对给定库中的文件。

The *-devel packages (usually called *-dev in Debian-based distributions) are usually all the files necessary to compile code against a given library.

有关使用该库运行的应用程序 libfoo的只有actualy共享库文件( *。所以* ,例如 libfoo.so.1.0 )的需要(再加上可能还有一些数据文件和一些特殊版本的符号连接)。

For running an application using the library libfoo only the actualy shared library file (*.so.*, for example libfoo.so.1.0) are needed (plus possibly some data files and some version-specific symlinks).

当你真的想编译使用该库则需要在头文件的C应用程序( *的.h ,例如富.H ),描述应用程序的接口,以及一个版本,少的符号链接到共享库( *。所以,例如 libfoo.so - > libfoo.so.1.0 )。这些通常被捆绑在。* - DEVEL

When you actually want to compile a C application that uses that library you'll need the header files (*.h, for example foo.h) that describe the interface of that application as well as a version-less symlink to the shared library (*.so, for example libfoo.so -> libfoo.so.1.0). Those are usually bundled in the *-devel packages.

有时 * - DEVEL 套餐还包括库静态编译版本( *一个,例如。 libfoo.a中)的情况下,你想建立一个不依赖于动态库都完整的独立的应用程序。

Sometimes the *-devel packages also include statically compiled versions of the libraries (*.a, for example libfoo.a) in case you want to build a complete stand-alone application that doesn't depend on dynamic libraries at all.

其他语言(如Java,Python和...)使用注意库的API(有效包括实际库中的所有必要信息)以不同的方式,因此,通常需要没有单独的 * - DEVEL 包(可能除了文档和其他工具)

Other languages (such as Java, Python, ...) use a different way of noting the API of a library (effectively including all the necessary information in the actual library) and thus usually need no separate *-devel packages (except maybe for documentation and additional tools).
