error: "va_start" used in Win64 ABI funtion getting thi seero in clang help me to solve this?

Question

我已经编译了，但是在 ubuntu 中使用 CLANG 进行编译时，我遇到了这样的错误："va_start" 在 Win64 ABI 函数中使用。谁能帮帮我？

Answer 1

因为你的函数是 static 和我怀疑你将它作为参数传递到任何地方，我相信你可以在这里删除 EFIABI （并在声明中）。 EFIABI 是一个 4 寄存器调用约定，GCC 似乎不支持可变参数。

Answer 2

根据 here. Use the builtins if you want to "cross-compile" between linux and windows targets, per here, also add __attribute__((ms_abi)), otherwise it will not work either, see these tests.

，

va_* 被 clang 明确禁止

static int
__attribute__((ms_abi))
va_Utimes(
  const char   *path,
  ...
  )
{
  __builtin_ms_va_list ap;

  __builtin_ms_va_start(ap, path);
  retval = ...ioctl( filp, FIOSETIME, ap);
  __builtin_ms_va_end(ap);

  return retval;
}
