在GCC中没有Makefile.am的Makefile.in吗? [英] Makefile.in without Makefile.am in GCC?

问题描述

我正在阅读GCC的源代码，并且有一些疑问.显然，GCC是使用自动工具构建的.但是我找不到automake所需的Makefile.am文件. GCC的Makefile.in文件是手写的吗?而且，如果它们是用手写的，那么在哪里可以找到描述Makefile.in语法的文档?

I'm reading GCC's source code and have some questions. It's obvious that GCC is build with autotools. But I couldn't find the Makefile.am files required by automake. Is GCC's Makefile.in files written by hand? And if they are written by hand, where can I find the documents describing the syntax of a Makefile.in?

一个类似的问题:在项目中没有Makefile.am的Makefile.in

推荐答案

Makefile.am是Autotools系列的更高版本，并非所有项目都使用它.海湾合作委员会特别不使用它.顶级Makefile.in是使用 autogen 从Makefile.tpl生成的(请参见此处).其他Makefile.in是根据

Makefile.am is a later addition to Autotools family and not all projects use it. GCC in particular does not use it. The top-level Makefile.in is generated from Makefile.tpl using autogen (see here for details). Other Makefile.in's are written by hand according to Autoconf rules.
