我有一些用C语言编写的软件,它编译得很好,但是当我试图将它打包成Nix包时,编译器会发出错误
未知的类型名“clockid”是指“clock”吗?
这是一个MCVE:
默认.nix:

with import <nixpkgs> {};
stdenv.mkDerivation {
  name = "asdf";
  src = lib.cleanSource ./.;
}

主要c:
#include <stdio.h>
#include <time.h>

clockid_t x;

int main() { return 0; }

生成文件:
all:
    cc main.c -o main

将这些文件放入目录并执行nix-build会产生以下输出:
these derivations will be built:
  /nix/store/8djs648bj3bqrn0bz51hmf79wdifks2b-asdf.drv

error: build of '/nix/store/8djs648bj3bqrn0bz51hmf79wdifks2b-asdf.drv' failed

但是当我简单地运行make时没有错误。我该怎么解决?

最佳答案

这似乎是一个编译错误,在OSX中从10.11.6开始就被修复了,您在派生中使用它。
升级到新的nixpkgs应该可以解决这个问题。尼克斯帕克斯18.09应该足够了。
