请教prefix的一个问题

jinglexy

chap6里面的：

../glibc-2.3.4/configure --prefix=/usr \
    --disable-profile --enable-add-ons \
    --enable-kernel=2.6.0 --libexecdir=/usr/lib/glibc

意思是安装库到/usr中去，但是随后的一节adjust好像说的是库在/lib中，
这事怎么回事阿？

thanks a lot

问题不引大家兴趣埃，好像是太简单了，呵呵。。结贴


一些参考:



well, both books LFS/BLFS say it's "your distro, your rules"
BLFS just gives you a wide varitey of options to choose from.
putting everything in --prefix=/usr just helps to keep things organized
and keep the main "system" files clean..........
you can always use --prefix=/opt/usr if you want further organize
your own programs.......
  




It keeps things simple if you install everything in /usr. If you install stuff elsewhere you then have to add that to /etc/ld.so.conf and extend your $PATH and $PKG_CONFIG_PATH to include the new files. It all gets too confusing for my little brain. Keep it simple, works for me.






EDIT: FWIW I use /usr in general, /opt for anything precompiled - Firefox, Open Office, Acrobat Reader and Java (lazy I know) - and /usr/local for testing before I put it into /usr.

基本上也是我的原则。。。

就是啊，如楼主所言的地方
在把glibc装好后，ldconfig和sln两个程序会被装到/sbin目录下，另外有些库也被装到/lib下，这里/sbin和/lib没有指定啊
那么在第五章中装glibc到/tools中时，有没有把ldconfig和sln装在/sbin把有些库装在/lib（这时/sbin和/lib还在宿主机上面了）？

hmm，，当年考虑过这个问题，后来也不了了之了。。。

我想的是：如果 prefix 指定为 /usr 的话，就会把部分库放入 /lib，如果不是的话，那么就全部放入相应的 /prefix 里边。。

glibc文档的解释：
GNU/Linux expects some components of the libc installation to be in
`/lib' and some in `/usr/lib'.  This is handled automatically if you
configure glibc with `--prefix=/usr'.  If you set some other prefix or
allow it to default to `/usr/local', then all the components are
installed there.

翻译：
如果指定prefix为/usr，则会安装glibc的组件到/lib和/usr/lib中，
如果指定为/usr/local，则只会安装到/usr/local/lib中

楼上正解～～～

向jinglexy学习！
幻想老大不用查glibc文档自己能想出来，强！
