【问题描述】:
我正在使用以下机器:
Linux version 5.4.0-42-generic (buildd@lgw01-amd64-038) (gcc version 9.3.0 (Ubuntu 9.3.0-10ubuntu2)) #46-Ubuntu SMP Fri Jul 10 00:24:02 UTC 2020
程序
int main() {
return 0;
}
编译时
gcc -Wl,-m main.c
返回
/usr/bin/ld: unrecognised emulation mode: /tmp/ccJI1LRo.o
Supported emulations: elf_x86_64 elf32_x86_64 elf_i386 elf_iamcu elf_l1om elf_k1om i386pep i386pe
collect2: error: ld returned 1 exit status
我不知道从哪里开始知道为什么。
还有 gcc 和 ld 版本:
> gcc --version
