gcc错误：错误的ELF类：ELFCLASS64 [英] gcc error: wrong ELF class: ELFCLASS64

问题描述

我试图使用外部编译对象coreset.o来编译程序。我写了public01.c测试文件，我的函数在comput.c中，两者都编译。然而它没有把它连接在一起。可能是什么问题？

  gcc -o public01.x public01.o comput.o coreset.o 
 ld ：fatal：文件coreset.o：错误的ELF类：ELFCLASS64 
 ld：fatal：文件处理错误。没有输出写入public01.x 
 collect2：ld返回1退出状态
  

解决方案

我认为coreset.o是为64位编译的，而且你正在使用32位计算来链接它。

你可以尝试使用 gcc（1）<-m64>标志重新编译computes.c / a>

I was trying to compile a program using an external compiled object coreset.o. I wrote the public01.c test file and my functions are in computation.c, both of which compiles. However its failing on linking it together. What might be the problem?

gcc -o public01.x public01.o computation.o coreset.o
ld: fatal: file coreset.o: wrong ELF class: ELFCLASS64
ld: fatal: File processing errors. No output written to public01.x
collect2: ld returned 1 exit status

解决方案

I think that coreset.o was compiled for 64-bit, and you are linking it with a 32-bit computation.o.

You can try to recompile computation.c with the '-m64' flag of gcc(1)
