我在AMD Athlon(tm)64 X2双核处理器5200×2上运行Ubuntu 12.10(64位),Linux内核3.5.0-51通用.我有GNU Fortran(Ubuntu / Linaro 4.7.2-2ubuntu1)4.7.2.
我正在尝试将一些代码编译成32位可执行文件.我已经检查过我的系统上安装了所有需要的库(我在以前在32位计算机上编译的程序上运行了ldd,并下载了丢失的软件包).我尝试运行$gfortran foo.f -m32 -L / lib / i386-linux-gnu,但是我收到以下错误：

我检查了/usr/lib/gcc/i686-linux-gnu/4.7和/usr/lib/gcc/i686-linux-gnu/4.7.2目录,它们都是空的.
你能帮我解决一下这个问题吗？我做了我的研究,但这是我能得到的.
先感谢您！
解决方法:
64位库/usr/lib / gcc / x86_64-linux-gnu / …不适用于32位编译.您需要安装multilib编译器软件包(请参阅https://help.ubuntu.com/community/InstallingCompilers).例如：
sudo apt-get install gfortran-multilib
现在gfortran -m32 foo.f应该可行.
