Fedora x86_64 上供应商库的 config.site

问题描述

我在 Fedora 26、x86_64 上构建一些基于 Autotool 的库时遇到问题.64 位 Fedora 将第三方和供应商库放在 /usr/local/lib64 中.Ubuntu 17 使用 /usr/local/lib 因此相同的项目可以正常构建.

I'm having trouble building a few Autotool-based libraries on Fedora 26, x86_64. The 64-bit Fedora puts third party and vendor libraries in /usr/local/lib64. Ubuntu 17 uses /usr/local/lib so the same projects build OK.

我一直在使用 --libdir=/usr/local/lib64 但有三个库抵制它.我缺少 /usr/local 的 config.site 所以我想添加一个.关于站点默认设置的 Autoconf 手册当它讨论 usr/local 的 config.site 时，我有点困惑.它说:

I've been using --libdir=/usr/local/lib64 but three libraries resist it. I lack a config.site for /usr/local so I am trying to add one. The Autoconf manual on Site Defaults is a tad bit confusing to me when it discusses usr/local's config.site. It says:

[讨论/usr版本的confg.site] ...

同样，在默认构建 64 位库的平台上，然后安装在/usr/local/lib64而不是/usr/local/lib中，它是适合安装/usr/local/share/config.site:

Likewise, on platforms where 64-bit libraries are built by default, then installed in /usr/local/lib64 instead of /usr/local/lib, it is appropriate to install /usr/local/share/config.site:

# /usr/local/share/config.site for platforms that prefer
# the directory /usr/local/lib64 over /usr/local/lib.
test "$libdir" = '${exec_prefix}/lib' && libdir='${exec_prefix}/lib64'

我遇到的问题是，上面的修改是否附加到了 config.site 的 /usr/local 版本?或者它是否替换了现有的代码块?或者我可以直接将它复制到它所属的地方而不做修改吗?

The problem I am having is, is the modification above appended to the /usr/local version of config.site? Or does it replace an existing block of code? Or can I just copy it where it belongs without modification?

或者，/usr/local/share/config.site 的猫是什么样子的?

Or maybe, what does a cat of /usr/local/share/config.site look like?

这是 /usr 的 config.site.我不清楚是否需要修改或如何修改.

Here is the config.site for /usr. Its not clear to me if it needs modification or how to modify it.

$ cat /usr/share/config.site
# This is the config.site file to satisfy FHS defaults when installing below
# /usr.
#
# You may override this file by your config.site using the CONFIG_SITE env
# variable.
#
# Note: This file includes also RHEL/Fedora fix for installing libraries into
# "/lib/lib64" on 64bit systems.

if test -n "$host"; then
    # skip when cross-compiling
    return 0
fi

if test "$prefix" = /usr
   || { test "$prefix" = NONE && test "$ac_default_prefix" = /usr ; }
then
    test "$sysconfdir" = '${prefix}/etc' && sysconfdir=/etc
    test "$sharedstatedir" = '${prefix}/com' && sharedstatedir=/var
    test "$localstatedir" = '${prefix}/var' && localstatedir=/var

    ARCH=`uname -m`
    for i in x86_64 ppc64 s390x aarch64; do
        if test $ARCH = $i; then
            test "$libdir" = '${exec_prefix}/lib' && libdir='${exec_prefix}/lib64'
            break
        fi
    done
fi

推荐答案

这回答了关于 /usr/local/share/config.site 的 config.site 是什么样子的问题.正如@John Bollinger 在评论中指出的那样，它没有回答为什么 --libdir=/usr/local/lib64 无法设置目录的问题.

This answers the question of what config.site looks like for /usr/local/share/config.site. It does not answer the question of why --libdir=/usr/local/lib64 fails to set the directory, as @John Bollinger pointed out in the comments.

/usr/local/share/config.site 是错误的.虽然它是从 Fedora 的 config.site 复制并放置在 /usr/local/share 中，但前缀目录是错误的.前缀测试应该使用 /usr/local 而不是 /usr.

The /usr/local/share/config.site is wrong. Though it was copied from Fedora's config.site and placed in /usr/local/share, the prefix directories are wrong. The prefix test should use /usr/local and not /usr.

以下是更正的.

$ cat /usr/local/share/config.site
...

if test -n "$host"; then
    # skip when cross-compiling
    return 0
fi

if test "$prefix" = /usr/local
   || { test "$prefix" = NONE && test "$ac_default_prefix" = /usr/local ; }
then
    test "$sysconfdir" = '${prefix}/etc' && sysconfdir=/etc
    test "$sharedstatedir" = '${prefix}/com' && sharedstatedir=/var
    test "$localstatedir" = '${prefix}/var' && localstatedir=/var

    ARCH=`uname -m`
    for i in x86_64 ppc64 s390x aarch64; do
        if test $ARCH = $i; then
            test "$libdir" = '${exec_prefix}/lib' && libdir='${exec_prefix}/lib64'
            break
        fi
    done
fi

不过，我不确定这些是否正确.它们没有被修改.

I'm not sure if these are correct, however. They were not modified.

test "$sysconfdir" = '${prefix}/etc' && sysconfdir=/etc
test "$sharedstatedir" = '${prefix}/com' && sharedstatedir=/var
test "$localstatedir" = '${prefix}/var' && localstatedir=/var

现在，下一个问题是，为什么 Fedora 的 /usr/share/config.site 没有正确处理 prefix=/usr/local.这是 问题 1510073 中的一个悬而未决的问题:Autoconf 不支持 config.site 中的 libdir 为libdir"=@libdir@" 在 *.pc 文件中，该文件已作为 NOT A BUG 关闭.

Now, the next question is, why Fedora's /usr/share/config.site is not handling prefix=/usr/local properly. That's an open question at Issue 1510073 : Autoconf does not honor libdir in config.site for "libdir=@libdir@" in *.pc file, which has been closed as NOT A BUG.
