libstdc++.so.6.0.17 32和64位

64bit 系统运行32bit软件兼容性问题，错误提示:libstdc++.so.6 not found,libstdc++.so.6.0.17 32和64位，可以使用，按要求放在相应的文件夹下就行了

/usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.15' not found (required by /opt/qtcreator-3.3.0/lib/qtcreator/plugins/.././libQt5CLucene.so.5) 压缩包中是linux的32和64位的库，可以使用file命令查看 将相应的库覆盖/usr/lib/libstdc++.so.6.0.13或其他版本的库，再运行qtcreator即可。

说明：

./INSTALL时，发现libstdc++.so.6 找不到。可是locate libstdc++.so.6 ,发现明明有的：

$ locate libstdc++.so.6 

/usr/lib/libstdc++.so.6

/usr/lib/libstdc++.so.6.0.13

于是。。。 先把 instcore 拿出来测试。

vowstar@vowstar-desktop:~/Downloads/Test$ ldd instcore 

Linux-gate.so.1 =>  (0xf777a000)

libQtXml.so.4 => not found

libQtGui.so.4 => not found

libQtCore.so.4 => not found

libpthread.so.0 => /lib32/libpthread.so.0 (0xf774c000)

libstdc++.so.6 => not found

libc.so.6 => /lib32/libc.so.6 (0xf75cc000)

/lib/ld-linux.so.2 (0xf777b000)

原来全链接到32位库去了, 于是想办法兼容32位：

$ sudo apt-get install ia32-libs ia32-libs-gtk linux32 lib32asound2
