根因分析

函数声明没有函数体，因为源文件被截断、函数定义在另一个未编译的文件中，或者构建标签导致函数体被排除。

English

A function declaration has no body because the source file was truncated, the function is defined in another file not compiled, or a build tag caused the body to be excluded.

解决方案

  1. Provide the missing function body: define the function with a block, e.g., `func foo() int { return 0 }`.
  2. If using build tags, ensure the file with the function body is included: `go build -tags "mytag" .` or remove conflicting tags.

无效尝试

常见但无效的做法:

  1. 95% 失败

    The compiler requires an actual block {} not just a return; the function must have a body.

  2. 80% 失败

    If the function is called elsewhere, removing it causes undefined errors.
