你使用的Go版本是什么( go version )?

go version go1.10.3 gccgo (GCC) 8.2.1 20180813 solaris/sparc

这个问题在最新版本中是否会重现？

是的。从源代码编译

你正在使用什么操作系统和处理器架构( go env )?

你做了什么？

尝试编译一个简单的程序：

  1. package main

  3. /*                                                                             
  4. #include <stdio.h>                                                             
  6. void testc() {                                                                 
  7.     printf("Hello cgo");
  8. }                                                                              
  9. */                                                                             
  10. import "C"                                                                     
  11.                                                                                
  12. func main() {                                                                  
  13.     C.testc()                                                                  
  14. }

你看到了什么？

编译失败，错误信息为：

从邮件列表中得知，这是一个32位SPARC处理器的问题，可能的原因是debug/elf包中的*File类型没有applyRelocationsSPARC方法。虽然有一个applyRelocationsSPARC64,但没有32位实现。

你好，@ianlancetaylor。我刚刚查看了源代码，发现已经存在实现：https://github.com/golang/gofrontend/blob/7b25b4dff4778fc4d6b5d6e10594814146b3e5dd/libgo/go/debug/elf/file.go#L1073
我是不是漏掉了什么？

对不起，您说得对。我正在查看gc源代码，但您使用的是gccgo。该函数在gccgo中存在。
我不确定这里发生了什么。
