我正在使用代码块。我正在使用ubuntu。这是编译的输出。

关于32位库的小信息:

miroslav@miroslav-desktop:/usr/lib32$ ls -la libst*
lrwxrwxrwx 1 root root     19 2010-06-21 20:50 libstdc++.so.6 -> libstdc++.so.6.0.13
-rw-r--r-- 1 root root 975088 2010-03-27 01:16 libstdc++.so.6.0.13

请务必安装gcc-multilibg++-multilib。这些都依赖于64作为32位gcc和stdc ++库。
