向 Autoconf 生成的配置脚本添加自定义安装目录选项 [英] Adding a custom installation directory option to Autoconf-generated configure scripts

问题描述

configure 脚本总是在帮助消息中包含如下内容:

<前>...默认情况下，`make install' 将安装所有文件`/usr/local/bin', `/usr/local/lib' 等你可以指定使用 `--prefix' 的除 `/usr/local' 之外的安装前缀，例如`--prefix=$HOME'.为了更好地控制，请使用以下选项.微调安装目录:--bindir=DIR 用户可执行文件 [EPREFIX/bin]--sbindir=DIR 系统管理员可执行文件 [EPREFIX/sbin]--libexecdir=DIR 程序可执行文件 [EPREFIX/libexec]--sysconfdir=DIR 只读单机数据 [PREFIX/etc]--sharedstatedir=DIR 可修改的与架构无关的数据 [PREFIX/com]--localstatedir=DIR 可修改的单机数据 [PREFIX/var]--libdir=DIR 目标代码库 [EPREFIX/lib]--includedir=DIR C 头文件 [PREFIX/include]--oldincludedir=DIR 非 gcc 的 C 头文件 [/usr/include]--datarootdir=DIR 只读 arch.-independent data root [PREFIX/share]--datadir=DIR 只读架构无关数据 [DATAROOTDIR]--infodir=DIR 信息文档 [DATAROOTDIR/info]--localedir=DIR 语言环境相关数据 [DATAROOTDIR/locale]--mandir=DIR man 文档 [DATAROOTDIR/man]--docdir=DIR 文档根目录[DATAROOTDIR/doc/gedit-line-ending-style-plugin]--htmldir=DIR html 文档 [DOCDIR]--dvidir=DIR dvi 文档 [DOCDIR]--pdfdir=DIR pdf 文档 [DOCDIR]--psdir=DIR ps 文档 [DOCDIR]程序名称:--program-prefix=PREFIX 在已安装的程序名前添加 PREFIX...

我想做的是在本节中添加plugindir"，如下所示:

<前>...--dvidir=DIR dvi 文档 [DOCDIR]--pdfdir=DIR pdf 文档 [DOCDIR]--psdir=DIR ps 文档 [DOCDIR]--plugindir=DIR Gedit 插件文件 [LIBDIR/gedit-2/plugins]...

以便用户能够将 --plugindir=... 传递给配置脚本.

我该怎么做?

解决方案

如果我没猜错，这些路径是在 share/autoconf/autoconf/general.m4 文件中设置的.该列表是硬编码的，因此很难在列表中插入内容.您可以使用宏 添加额外的帮助信息AS_HELP_STRING.有一些添加 plugindir 的示例，例如在 gstreamer, gimp，但是那些没有可配置的插件目录.

configure scripts always include something like the following in the help message:

...
By default, `make install' will install all the files in
`/usr/local/bin', `/usr/local/lib' etc.  You can specify
an installation prefix other than `/usr/local' using `--prefix',
for instance `--prefix=$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]
  --libexecdir=DIR        program executables [EPREFIX/libexec]
  --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
  --libdir=DIR            object code libraries [EPREFIX/lib]
  --includedir=DIR        C header files [PREFIX/include]
  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
  --infodir=DIR           info documentation [DATAROOTDIR/info]
  --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]
  --mandir=DIR            man documentation [DATAROOTDIR/man]
  --docdir=DIR            documentation root
                          [DATAROOTDIR/doc/gedit-line-ending-style-plugin]
  --htmldir=DIR           html documentation [DOCDIR]
  --dvidir=DIR            dvi documentation [DOCDIR]
  --pdfdir=DIR            pdf documentation [DOCDIR]
  --psdir=DIR             ps documentation [DOCDIR]

Program names:
  --program-prefix=PREFIX            prepend PREFIX to installed program names
...

What I would like to do is add "plugindir", to this section, as in:

...
  --dvidir=DIR            dvi documentation [DOCDIR]
  --pdfdir=DIR            pdf documentation [DOCDIR]
  --psdir=DIR             ps documentation [DOCDIR]
  --plugindir=DIR         Gedit plugin files [LIBDIR/gedit-2/plugins]
...

so that users would be able to pass in --plugindir=... to the configure script.

How can I do this?

解决方案

If I'm correct those paths are set in the share/autoconf/autoconf/general.m4 file. The list is hardcoded so it is difficult to insert things in the list. You can add extra help information using the macro AS_HELP_STRING. There are some examples that add a plugindir, for example in gstreamer, gimp, but those don't have a configurable plugin directory.
