linux(64位的系统)下nasm进行汇编链接时出现的问题

出现问题：

$nasm -f elf hello.asm -o hello.o

$ld -s hello.o -o hello

　　ld: i386 architecture of input file `hello.o' is incompatible with i386:x86-64 output

 

-------------------------------------------------------------------------------------------------------

 

尝试：

$ ld -m32 -s hello.o -o hello
　　ld: unrecognised emulation mode: 32
　　Supported emulations: elf_x86_64 elf32_x86_64 elf_i386 i386linux elf_l1om elf_k1om i386pep i386pe

 -------------------------------------------------------------------------------------------------------

 

 

解决：

$nasm -f elf hello.asm -o hello.o

$ld -m elf_i386 -s hello.o -o hello

$./hello

　　Hello, world!
