C:找不到主目录，但是在那儿|编译错误 [英] C: main not found, but it's there | Compilation error

问题描述

当我像下面给出的那样编译两个.c文件时，我得到了一个非常奇怪的错误.

When I compile two .c files like given below I get a really weird error.

在终端上编译的代码

  gcc -I. -o main.c matrix.c -lblas -lgfortran

错误:

  /usr/bin/ld: /usr/lib/debug/usr/lib/i386-linux-gnu/crt1.o(.debug_info): relocation 0 has invalid symbol index 11
  /usr/bin/ld: /usr/lib/debug/usr/lib/i386-linux-gnu/crt1.o(.debug_info): relocation 1 has invalid symbol index 12
  /usr/bin/ld: /usr/lib/debug/usr/lib/i386-linux-gnu/crt1.o(.debug_info): relocation 2 has invalid symbol index 2
  /usr/bin/ld: /usr/lib/debug/usr/lib/i386-linux-gnu/crt1.o(.debug_info): relocation 3 has invalid symbol index 2

  /usr/bin/ld: /usr/lib/debug/usr/lib/i386-linux-gnu/crt1.o(.debug_info): relocation 6 has invalid symbol index 13
  ...

我做了一些阅读，解决的方法似乎是添加一个主文件.但是我知道，在编译之前，我的main.c文件中包含int main(). 这是编译之前所有内容的列表:

I did a bit of reading and the solution seems to be to add a main file. But I know for a fact I had the main.c file with the int main() in it before compiling. Here's the list of everything before compiling:

  > ls
  errors.txt  main.c  main.c~  matrix.c  matrix.c~  matrix.h  matrix.h~

编译后，这是所有内容的列表:

After compilation this is the list of everything present:

  > ls
  errors.txt  main.c~  matrix.c  matrix.c~  matrix.h  matrix.h~

由于某种原因，每次编译时main.c都会被删除.奇怪的是，直到几分钟前，一切都运转良好.有人可以帮忙吗?

For some reason my main.c is getting deleted everytime I compile. What's weird is everything was working perfectly till a couple of minutes ago. Can someone help?

推荐答案

gcc -I. -o main.c matrix.c -lblas -lgfortran

-o main.c告诉编译器将其编译后的输出写入文件main.c，这可能不是您想要的.您可能想要:

the -o main.c tells the compiler to write its compiled output into the file main.c, which is probably not what you want. You probably want:

gcc -I. -o progname main.c matrix.c -lblas -lgfortran
