提问by kravemir
I'm using codeblocks. I'm using ubuntu. Here is output of compilation.
我正在使用代码块。我正在使用 ubuntu。这是编译的输出。

Little info about 32bit libs:
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

Be sure to install gcc-multiliband g++-multilib. These depend on both the 64 as the 32-bit gcc and stdc++ libraries.
一定要安装gcc-multilib和g++-multilib。这些依赖于 64 位作为 32 位 gcc 和 stdc++ 库。
