构建glibc时出错：make / confgure文件出了什么问题？ [英] Errors building glibc: what is wrong with the make/confgure files?

问题描述

我一直在尝试在Clear Linux上构建glibc，此处讨论了先前的问题：
如何使用前缀将其构建到指定的目录中

I have been trying to build glibc on Clear Linux, with a previous issue discussed here: How do I build into a specified directory using the "prefix" option of configure?

现在我已经成功运行了configure，makefile文件似乎出现了问题：

Now that I have succeeded in running configure, there seems to be something wrong in the makefile:

james@clr ~/Downloads/glibc $ make
Makeconfig:42: *** missing separator.  Stop.

Makeconfig的第42行：

line 42 of Makeconfig:

objdir must be defined by the build-directory Makefile.

和nakefile直到错误点：

and the nakefile up to the point of error:

ifneq (,)
This makefile requires GNU Make.
endif

all: # Make this the default goal

ifneq "$(origin +included-Makeconfig)" "file"

+included-Makeconfig := yes

ifdef subdir
.. := ../
endif

# $(common-objdir) is the place to put objects and
# such that are not specific to a single subdir.
ifdef objdir
objpfx := $(patsubst %//,%/,$(objdir)/$(subdir)/)
common-objpfx = $(objdir)/
common-objdir = $(objdir)
else
objdir must be defined by the build-directory Makefile.
endif

我有GNU Make 4.2.1

I have GNU Make 4.2.1

推荐答案

您看到一个错误，因为此Makefile认为您的环境是错误的。您正在运行的makefile中的行是有目的的语法错误：无需过多地编辑这些行即可将其更改为正确的行，因为其整个目的是在看到无效的配置时强制make失败。

You're seeing an error because this makefile thinks your environment is wrong. The line in the makefile that you're running is purposefully a syntax error: no amount of editing these lines will change it into a correct line because its entire purpose is to force make to fail when it sees an invalid configuration.

它试图告诉您的错误就在文本中：

The error it's trying to tell you about is right there in the text:

objdir必须由构建目录的Makefile定义。

objdir must be defined by the build-directory Makefile.

makefile检查是否 变量已定义，如果没有定义，它就属于这种无效的语法。

The makefile checks to see if the objdir variable is defined and if not, it falls through to this invalid syntax.

我已经有一段时间没有尝试自己构建glibc了，所以我可以不能确切地说出这是什么意思，但是我敢肯定，如果您在Google上看到该错误消息，您会找到一些可以让您继续前进的信息。

I haven't tried to build glibc myself in quite a while so I can't say exactly what that means but I'm sure if you Google that error message you'll find some information that will let you move forward.

makefile不使用更易读的方式指定错误，例如 $（error ...）函数（在1999年发布的GNU make 3.78中添加）。

It's too bad that this makefile doesn't use more readable ways of specifying errors such as the $(error ...) function (added in GNU make 3.78, released in 1999).
