我有点难过。这是我从gcc
获得的错误gcc -lm -g -o bin/tomashell obj/tomashell.o obj/tomashell.o: In function `_start': (.text+0x0): multiple definition of `_start' /usr/bin/ld: /usr/lib/debug/usr/lib/crt1.o(.debug_info): relocation 0 has invalid symbol index 12 /usr/bin/ld: /usr/lib/debug/usr/lib/crt1.o(.debug_info): relocation 1 has invalid symbol index 13 /usr/bin/ld: /usr/lib/debug/usr/lib/crt1.o(.debug_info): relocation 2 has invalid symbol index 2 /usr/bin/ld: /usr/lib/debug/usr/lib/crt1.o(.debug_info): relocation 3 has invalid symbol index 2 /usr/bin/ld: /usr/lib/debug/usr/lib/crt1.o(.debug_info): relocation 4 has invalid symbol index 12 /usr/bin/ld: /usr/lib/debug/usr/lib/crt1.o(.debug_info): relocation 5 has invalid symbol index 14 /usr/bin/ld: /usr/lib/debug/usr/lib/crt1.o(.debug_info): relocation 6 has invalid symbol index 14 /usr/bin/ld: /usr/lib/debug/usr/lib/crt1.o(.debug_info): relocation 7 has invalid symbol index 14 /usr/bin/ld: /usr/lib/debug/usr/lib/crt1.o(.debug_info): relocation 8 has invalid symbol index 2 /usr/bin/ld: /usr/lib/debug/usr/lib/crt1.o(.debug_info): relocation 9 has invalid symbol index 2 /usr/bin/ld: /usr/lib/debug/usr/lib/crt1.o(.debug_info): relocation 10 has invalid symbol index 13 /usr/bin/ld: /usr/lib/debug/usr/lib/crt1.o(.debug_info): relocation 11 has invalid symbol index 14 /usr/bin/ld: /usr/lib/debug/usr/lib/crt1.o(.debug_info): relocation 12 has invalid symbol index 14 /usr/bin/ld: /usr/lib/debug/usr/lib/crt1.o(.debug_info): relocation 13 has invalid symbol index 14 /usr/bin/ld: /usr/lib/debug/usr/lib/crt1.o(.debug_info): relocation 14 has invalid symbol index 14 /usr/bin/ld: /usr/lib/debug/usr/lib/crt1.o(.debug_info): relocation 15 has invalid symbol index 14 /usr/bin/ld: /usr/lib/debug/usr/lib/crt1.o(.debug_info): relocation 16 has invalid symbol index 14 /usr/bin/ld: /usr/lib/debug/usr/lib/crt1.o(.debug_info): relocation 17 has invalid symbol index 14 /usr/bin/ld: /usr/lib/debug/usr/lib/crt1.o(.debug_info): relocation 18 has invalid symbol index 14 /usr/bin/ld: /usr/lib/debug/usr/lib/crt1.o(.debug_info): relocation 19 has invalid symbol index 14 /usr/bin/ld: /usr/lib/debug/usr/lib/crt1.o(.debug_info): relocation 20 has invalid symbol index 14 /usr/bin/ld: /usr/lib/debug/usr/lib/crt1.o(.debug_info): relocation 21 has invalid symbol index 14 /usr/bin/ld: /usr/lib/debug/usr/lib/crt1.o(.debug_info): relocation 22 has invalid symbol index 22 /usr/bin/ld: /usr/lib/debug/usr/lib/crt1.o(.debug_line): relocation 0 has invalid symbol index 2 /usr/lib/gcc/i486-linux-gnu/4.4.5/../../../../lib/crt1.o:/build/buildd-eglibc_2.11.2-10-i386-GapcyD/eglibc-2.11.2/csu/../sysdeps/i386/elf/start.S:119: first defined here obj/tomashell.o:(.rodata+0x0): multiple definition of `_fp_hw' /usr/lib/gcc/i486-linux-gnu/4.4.5/../../../../lib/crt1.o:(.rodata+0x0): first defined here obj/tomashell.o: In function `_fini': (.fini+0x0): multiple definition of `_fini' /usr/lib/gcc/i486-linux-gnu/4.4.5/../../../../lib/crti.o:(.fini+0x0): first defined here obj/tomashell.o:(.rodata+0x4): multiple definition of `_IO_stdin_used' /usr/lib/gcc/i486-linux-gnu/4.4.5/../../../../lib/crt1.o:(.rodata.cst4+0x0): first defined here obj/tomashell.o: In function `__data_start': (.data+0x0): multiple definition of `__data_start' /usr/lib/gcc/i486-linux-gnu/4.4.5/../../../../lib/crt1.o:(.data+0x0): first defined here obj/tomashell.o: In function `__data_start': (.data+0x4): multiple definition of `__dso_handle' /usr/lib/gcc/i486-linux-gnu/4.4.5/crtbegin.o:(.data+0x0): first defined here obj/tomashell.o: In function `_init': (.init+0x0): multiple definition of `_init' /usr/lib/gcc/i486-linux-gnu/4.4.5/../../../../lib/crti.o:(.init+0x0): first defined here /usr/lib/gcc/i486-linux-gnu/4.4.5/crtend.o:(.dtors+0x0): multiple definition of `__DTOR_END__' obj/tomashell.o:(.dtors+0x4): first defined here collect2: ld returned 1 exit status make: *** [bin/tomashell] Error 1
这是我的整个代码文件：
#include <stdlib.h>
#include <stdio.h>
int main()
{
printf("Hello, world!");
}
我没有丝毫的线索，为什么这不是编译。我正在编译所有其他C应用程序。

obj/tomashell.o不是对象文件，而是可执行文件。您可能在编译时忘记使用-c，因此（默认情况下）gcc输出可执行文件而不是目标文件。
