由于本人没有系统的学习过编译原理所以只好从代码反推,如有不对请及时指出,我们一起进步。

一、目录结构
整体上gcc的源码分成了核心代码和配套工具两部分,配套的工具主要是开源协议、使用方法、出处,自动化生成编译链的脚本,编译配置文件等等。
二、有意思的小功能
这个是国际化功能的说明文件,gcc支持用不同的语言打印错误里面介绍了输入什么样的参数可以通过configure脚本去配置这些功能。
需要注意的是这些语言不是全都直接支持的,所以用的时候要根据提示去下载对应的语言包。下面是截取的一段描述,顺便给大家科普下这些语言的含义。
- am:在拉丁语中,“am”是“ante meridiem”的缩写,意为“上午”。但在此语言代码的语境下,它通常不表示这个含义。
- az:阿塞拜疆语。在阿塞拜疆语中,“az”还有“蓝色”的意思,因为阿塞拜疆的国家旗帜和国徽上均有蓝色的元素。
- be:白俄罗斯语。也有资料将其列为比利时语(但在语言学上,比利时主要使用荷兰语、法语和德语等语言,没有所谓的“比利时语”)。不过,根据更广泛接受的国际标准,be通常代表白俄罗斯语。
- bg:保加利亚语。
- ca:加泰罗尼亚语。此外,“ca.”是拉丁语“circa”的缩写,意为“大约”。但在语言代码的语境中,“ca”通常指加泰罗尼亚语。
- cs:捷克语。
- da:丹麦语。
- de:德语。
- el:希腊语。
- en:英语。它是一个通用代码,代表英语这种语言。
- en_GB:特指英国的英语。它是英语的一个地域变体代码,表示英国地区使用的英语。
- eo:世界语(Esperanto),这是一种人造的国际辅助语言。
- es:西班牙语。
- et:爱沙尼亚语(Estonian)
- fa:波斯语(Farsi 或 Persian),虽然“fa”更常被看作是波斯语的代码,但在某些上下文中也可能代表法尔斯语(Fars language),但两者实际上是同一种语言。
- fi:芬兰语(Finnish)
- fr:法语(French)
- ga:爱尔兰语(Gaelic 或 Irish),在爱尔兰共和国,这种语言有时也被称为Gaeilge。
- gl:加利西亚语(Galician),这是一种在西班牙加利西亚自治区使用的语言,与葡萄牙语相近。
- he:希伯来语(Hebrew)
- hr:克罗地亚语(Croatian)
- hu:匈牙利语(Hungarian)
- id:印度尼西亚语(Indonesian)
- it:意大利语(Italian)
- ja:日语(Japanese)
- ko:韩语(Korean)
- lg:卢旺达语(Luganda)或加纳的利圭利亚语(Lingua Franca of the Congo),但更常见的是指卢旺达语。
- lt:立陶宛语(Lithuanian)
- lv:拉脱维亚语(Latvian)
- ms:马来语(Malay)
- nb:挪威博克马尔语(Norwegian Bokmål),是挪威的两种官方语言之一。
- nl:荷兰语(Dutch),在比利时也被广泛使用,但比利时的荷兰语有时会被单独标识为“fl”或“nl_BE”。
- nn:挪威尼诺斯克语(Norwegian Nynorsk),也是挪威的官方语言之一,与博克马尔语并行使用。
- no:这是一个通用的挪威语代码,但在具体使用时,可能会更具体地指向“nb”(博克马尔语)或“nn”(尼诺斯克语)。
- pl:波兰语(Polish)
- pt:葡萄牙语(Portuguese),这是一个通用的代码,可能指向葡萄牙本土使用的葡萄牙语,也可能指向其他地区(如巴西)的葡萄牙语变体。
- pt_BR:特指巴西的葡萄牙语(Brazilian Portuguese),是葡萄牙语在巴西的变体。
- ro:罗马尼亚语(Romanian)
- ru:俄语(Russian)
- sk:斯洛伐克语(Slovak)
- sl:斯洛文尼亚语(Slovenian)
- sr:塞尔维亚语(Serbian)
- sv:瑞典语(Swedish)
- ta:泰米尔语(Tamil),主要在印度、斯里兰卡、新加坡、马来西亚、斐济等地的印度裔社群中使用。
- tr:土耳其语(Turkish)
- uk:乌克兰语(Ukrainian)
- vi:越南语(Vietnamese)
- wa:瓦隆语(Walloon),又称瓦隆尼亚语或华隆语,是比利时瓦隆尼亚地区的一种罗曼语族语言。
- zh_CN:简体中文(Chinese Simplified for Mainland China),是中华人民共和国大陆地区使用的官方语言形式。
- zh_TW:繁体中文(Chinese Traditional for Taiwan),是中国台湾地区以及海外部分华人社区中常用的中文书写形式。
一共有五十中语言,上面那些数字表示他们支持该种语言的包的数量,我们会发现很多语言是0.但是为什么要有呢。这些代码都是ISO 639语言代码的一部分,用于在国际交流中唯一标识各种语言。在软件开发、国际交流、网络内容标识等领域中,这些代码经常被用来指定用户界面的语言设置、翻译文件的语言标识等。其实我们常见的就是俩zh_CN和en。其实这些语言包的数量也可以从侧面看出各国在国际上热爱开源事业的开发者数量。一个国家喜欢开源的人多,他们的语言包就会多。当然能出现在这里的语言就已经是国际上比较有影响力的国家了。
不愧是前辈 1991年就开始做了,比我年龄都大哈哈。

脚本变量和设置
scriptversion
: 脚本版本。nl
: 换行符。IFS
: 输入字段分隔符。doit
: 用于执行命令,可以被设置为echo
来测试脚本。doit_exec
: 根据doit
的值设置,用于执行实际的命令或输出命令。
程序名称变量
chgrpprog
: 改变文件组的程序,默认为chgrp
。chmodprog
: 改变文件模式的程序,默认为chmod
。chownprog
: 改变文件所有者的程序,默认为chown
。cmpprog
: 比较两个文件的程序,默认为cmp
。cpprog
: 复制文件的程序,默认为cp
。mkdirprog
: 创建目录的程序,默认为mkdir
。mvprog
: 移动或重命名文件的程序,默认为mv
。rmprog
: 删除文件的程序,默认为rm
。stripprog
: 去除符号表和重定位信息的程序,默认为strip
。
模式和命令
mode
: 安装文件的期望模式,默认为0755
。chgrpcmd
,chmodcmd
,chowncmd
,mvcmd
,rmcmd
,stripcmd
: 根据上述程序名称变量构建的具体命令。
参数解析
脚本支持多种参数,包括:
-c
: 被忽略。-C
: 仅在目标文件不同的情况下安装(保留最后的数据修改时间)。-d
: 创建目录而不是安装文件。-g GROUP
: 将安装的文件改变为指定的组。-m MODE
: 将安装的文件改变为指定的模式。-o USER
: 将安装的文件改变为指定的用户。-s
: 去除安装文件的符号表和重定位信息。-t DIRECTORY
: 安装到指定的目录。-T
: 如果目标文件是目录,则报告错误。--version
: 显示版本信息并退出。--help
: 显示帮助信息并退出。
主要逻辑
- 参数解析:脚本首先解析传入的参数,并根据参数设置相应的变量。
- 目录创建:如果
-d
参数被设置,脚本将创建指定的目录。 - 文件安装:对于每个源文件,脚本将根据参数复制到目标位置,并设置相应的权限和所有权。
- 错误处理:脚本在复制文件前后使用
trap
命令来处理可能的错误,并确保临时文件被清理。 - 模式和所有权设置:脚本在复制文件后,根据参数设置文件的模式和所有权。
这个脚本其实没什么具体操作主要是起到了配置的作用

# Convert paths to host format when used with build tools.
# Intended for use with "native" mingw (where libtool itself
# is running under the msys shell), or in the following cross-
# build environments:
# $build $host
# mingw (msys) mingw [e.g. native]
# cygwin mingw
# *nix + wine mingw
# where wine is equipped with the `winepath' executable.
# In the native mingw case, the (msys) shell automatically
# converts paths for any non-msys applications it launches,
# but that facility isn't available from inside the cwrapper.
# Similar accommodations are necessary for $host mingw and
# $build cygwin. Calling this function does no harm for other
# $host/$build combinations not listed above.

# ARG is the path (on $build) that should be converted to
# the proper representation for $host. The result is stored
