请大家指点一下，我的linux版本是linux 2.6.32-220.el6.x86_64 #1 SMP Wed Nov 9 08:03:13 EST 2011 x86_64 x86_64 x86_64 GNU/Linux
ar的版本是
GNU ar version 2.20.51.0.2-5.28.el6 20091009

我想编译一个64位库，结果没有发现相应的选项，一个劲的报
ar: illegal option -- 6
Usage: ar [emulation options] [-]{dmpqrstx}[abcfilNoPsSuvV] [member-name] [count] archive-file file...
   ar -M [<mri-script]
commands:
  d          - delete file(s) from the archive
  m[ab]       - move file(s) in the archive
  p          - print file(s) found in the archive
  q[f]       - quick append file(s) to the archive
  r[ab][f][u]  - replace existing or insert new file(s) into the archive
  t          - display contents of archive
  x[o]       - extract file(s) from the archive
command specific modifiers:
  [a]       - put file(s) after [member-name]
  [b]       - put file(s) before [member-name] (same as [i])
  [D]       - use zero for timestamps and uids/gids
  [N]       - use instance [count] of name
  [f]       - truncate inserted file names
  [P]       - use full path names when matching
  [o]       - preserve original dates
  [u]       - only replace files that are newer than current archive contents
generic modifiers:
  [c]       - do not warn if the library had to be created
  [s]       - create an archive index (cf. ranlib)
  [S]       - do not build a symbol table
  [T]       - make a thin archive
  [v]       - be verbose
  [V]       - display the version number
  @<file>    - read options from <file>
emulation options:
  No emulation specific options
ar: supported targets: elf64-x86-64 elf32-i386 a.out-i386-linux pei-i386 pei-x86-64 elf64-l1om elf64-little elf64-big elf32-little elf32-big srec symbolsrec verilog tekhex binary ihex

那位知道帮我看一下，在网上查了半天都没有64位的方法，都说-m64或者-X64，但是我的ar没有这个选项呀。

问题已经解决，在此做一个总结，方便遇到一样问题的人参考；
AIX操作系统下，ar是有-X32 -X64 -X32_64三种模式的，因此使用者可以根据自己的需要选择模式，如果想我一样要使用configure编译的软件，请使用如下办法编译64位或者32位库
$ CFLAGS=-q64 FFLAGS=-q64 CXXFLAGS=-q64 AR='ar -X64'\
./configure
或者
$ export CFLAGS=-q64
$ export FFLAGS=-q64
$ export CXXFLAGS=-q64
$ export AR='ar -X64'
$ ./configure

在linux下由于没有-X选项（至少我的版本没有），可以使用OBJECT_MODE环境变量指定，方法如下：
$ export CFLAGS=-m64
$ export FFLAGS=-m64
$ export CXXFLAGS=-m64
$ export OBJECT_MODE=64
$ ./configure

上述，是我的总结经验，目前已经成功，如果大家有什么更好的办法，欢迎上来，大家共享一下。
