我在64位机器上使用ubuntu 12.04,我有这个简单的C代码:
int b = 20;
int c = 10;
int main(int argc, char **argv) {
c = 50;
}
我试图通过编译它来与任何IA32机器兼容:
unix> gcc -m32 code.c
并且遇到了这些错误:
/usr/bin/ld: cannot find crt1.o: No such file or directory
/usr/bin/ld: cannot find crti.o: No such file or directory

据我了解,这种情况正在发生,因为我缺少32位标准C库,因此链接器无法将我的代码与标准C库链接。
如何在64位机器上获得所需的32位标准C?
答案 0 :(得分:5)
试试这个:
apt-get install ia32-libs
此外,您应该使用-m32编译/链接:
gcc -Wall -pedantic -m32 ...
