Ubuntu Bits Complie Bits Assembly

64位Ubuntu系统编译32位汇编

汇编链接生成可执行文件

ld -o eatsyscall eatsycscall.o

输出

ld:i386 architecture of input file eatsyscall.o' is incompatible with i386:x86-64 ouput

解决

经过搜索64位下ld提供了一个选项-m emulation，简写-m。说明文档如下：

-m emulation
       Emulate the emulation linker. You can list the available
       emulations with the --verbose or -V options.

       If the -m option is not used，the emulation is taken from the
       "LDEMULSYION" environment variable，if that is defined.

       Otherwise，the default emulation depends upon how the linker was
       configured.

即，这个选项可以模拟其他平台上的ld链接器。使用-m elf_i386可以模拟32位平台上 ld指令。
