[升级] prelink 更新至 0.3.2
用于加快大型程序启动。这是最新版本。安装后请运行：prelink -afmR
请耐心等待，非常费时间。会有一些报错，目前未发现不良影响，但仍建议慎重使用。如果有重要库文件升级，或者安装大量软件包，请重新运行此命令。

大家看看台湾翻译的 gentoo 手册关于 prelink 的部分。

分析：
1. magic beta3 有些文件的确缺，否则就不会有那么多毁损的依赖关系。
2. 如果不支持编译参数 －fPIC 的库不能 prelink。
但这些没有大碍。 一些说明(来自 man gcc)：
-fpic
Generate position-independent code (PIC) suitable for use in a
shared library, if supported for the target machine.Such code
accesses all constant addresses through a global offset table
(GOT).The dynamic loader resolves the GOT entries when the pro-
gram starts (the dynamic loader is not part of GCC; it is part of
the operating system).If the GOT size for the linked executable
exceeds a machine-specific maximum size, you get an error message
from the linker indicating that -fpic does not work; in that case,
recompile with -fPIC instead.(These maximums are 16k on the m88k,
8k on the SPARC, and 32k on the m68k and RS/6000.The 386 has no
such limit.)
Position-independent code requires special support, and therefore
works only on certain machines.For the 386, GCC supports PIC for
System V but not for the Sun 386i.Code generated for the IBM
RS/6000 is always position-independent.
-fPIC
If supported for the target machine, emit position-independent
code, suitable for dynamic linking and avoiding any limit on the
size of the global offset table.This option makes a difference on
the m68k, m88k, and the SPARC.
Position-independent code requires special support, and therefore
works only on certain machines.
-fpie
-fPIE
These options are similar to -fpic and -fPIC, but generated posi-
tion independent code can be only linked into executables.Usually
these options are used when -pie GCC option will be used during
linking. ftp://ftp.univie.ac.at/systems/linux/fedora/updates/3/i386/prelink-0.3.3-0.fc3.i386.rpm http://www.gentoo.org/doc/en/prelink-howto.xml 我补充 补充 早就升级到 0.3.3 了。不要向我们提供 rpm，我们不能使用非本地编译版本，若有好的 src.rpm 可以推荐。 :? 一番好意 结果.. :cry: 谢谢你。 :mrgreen: 不过使用其他发行版的 rpm 会引入依赖问题，而且可能有其他隐含风险，比如 rpm 内嵌的脚本可能修改系统配置。 这么严重阿:o
