gcc-m32错误/usr/bin/ld:跳过不兼容

我正在尝试为

64位

和

32位

系统编译一个应用程序。在编译过程中，我收到

32位

应用程序的错误：

/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.9/libstdc++.so when searching for -lstdc++
/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.9/libstdc++.a when searching for -lstdc++

我四处阅读，发现我需要

gcc multilib

，所以我尝试安装它：

me@ubuntu:~/bin/c/find-files$ sudo apt-get install gcc-multilib
Reading package lists... Done
Building dependency tree       
Reading state information... Done
gcc-multilib is already the newest version (4:5.3.1-1ubuntu1).
The following packages were automatically installed and are no longer required:
  linux-headers-4.8.0-41 linux-headers-4.8.0-41-generic
  linux-image-4.8.0-36-generic linux-image-4.8.0-41-generic
  linux-image-extra-4.8.0-36-generic linux-image-extra-4.8.0-41-generic
Use 'sudo apt autoremove' to remove them.

它已经安装好了。因此，我再看一下，发现我应该导出到

lib32

目录：

me@ubuntu:~/bin/c/find-files$ export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/lib32:/usr/lib32:/usr/lib/i386-linux-gnu

再次尝试编译，出现相同错误。然后我想如果我使用

g++

并安装它的multilib：

me@ubuntu:~/bin/c/find-files$ sudo apt-get install g++-multilib

如何为

32位

和

64位

操作系统交叉编译应用程序
