ubuntu /usr/include/c++/11/ 下的文件报错

1. 把 min()和 max()函数里调用_UniformRandomBitGenerator::min()和_UniformRandomBitGenerator::max();的定义去掉 constexpr 修饰。

2. static_assert 改为 assert

@elfive 我是要 修改 /usr/include/c++/11/bits/uniform_int_dist 这些底层文件是吗？ 修改后 会对其他代码编译什么的受影响吗

@elfive 方法 1 成功解决一部分，但是方法 2 好像不行还是报错了 出现了两个新的错误
In file included from /usr/include/c++/11/bits/stl_algo.h:66,

@elfive static_assert( __urngmin < __urngmax, "Uniform random bit generator must define min() < max()");

我删除 static_ 后 就是上面的报错

@hhhhhh123 ……
static_assert 是编译期断言，后面第二个参数是断言失败的输出错误信息……
assert 是运行时断言，只有一个参数，你删除第二个参数不就好了……

@elfive 好像还是不行， 弄了就出新的一堆错误

@elfive 这是修改后的
__uctype __urngmin = _UniformRandomBitGenerator::min();
__uctype __urngmax = _UniformRandomBitGenerator::max();
assert( __urngmin < __urngmax);

报错信息变多了....

@hhhhhh123 输出信息都告诉你了 std::function 没有定义，也提示你是不是忘记了#include <functional>头文件……

你得去把 C/C++基础打牢点……

@elfive 我不是 c++开发，是 python 开发

@elfive 在上面写了
#ifndef _GLIBCXX_BITS_UNIFORM_INT_DIST_H
#define _GLIBCXX_BITS_UNIFORM_INT_DIST_H

#include <type_traits>
#include <ext/numeric_traits.h>
#if __cplusplus > 201703L
# include <concepts>
#endif
#include <bits/concept_check.h> // __glibcxx_function_requires
#include <functional>


但是错误好像还是这个

@hhhhhh123 这么跟你说吧，你用的这个库或者可能是别人写的代码，感觉应该不是 c++11 标准下的东西。
做法也无非是
1. 要么用新的 gcc ，并且使用编译参数设置适合的 c++标准；
2. 要么更换旧版本的库，满足 c++11 标准或者你指定的某一 c++标准。

这些问题再这么弄下去，真不知道会不会弄得完（清零）

@elfive gcc 都是最新的。 这不是源码吗？ 应该是官方的吧

@elfive 请教一下，win 本地 make 能 ok ， 但是在服务器就找不到一个文件， 这是没有指定路径还是啥？
