binutils

GNU 软件中重要的一员，是一个包含了若干核心二进制工具的软件包。在部分环境中并没有默认安装（比如当你发现你的 Linux 系统中 readelf 和 objdump 命令不存在），此时就找你的包管理器从软件源中 install 一下 binutils 包吧。 The GNU Binutils are a collection of binary tools. The main ones are:

• ld - the GNU linker.

• as - the GNU assembler.

But they also include:

• addr2line - Converts addresses into filenames and line numbers.

• ar - A utility for creating, modifying and extracting from archives.

• c++filt - Filter to demangle encoded C++ symbols.

• dlltool - Creates files for building and using DLLs.

• gold - A new, faster, ELF only linker, still in beta test.

• gprof - Displays profiling information.

• nlmconv - Converts object code into an NLM.

• nm - Lists symbols from object files.

• objcopy - Copies and translates object files.

• objdump - Displays information from object files.

• ranlib - Generates an index to the contents of an archive.

• readelf - Displays information from any ELF format object file.

• size - Lists the section sizes of an object or archive file.

• strings - Lists printable strings from files.

• strip - Discards symbols.

• windmc - A Windows compatible message compiler.

• windres - A compiler for Windows resource files.
