linux – gfortran：在64位系统中编译32位可执行文件

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：

/usr/bin/ld: cannot find crt1.o: No such file or directory

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！
