在将源文件从我的项目移动到子目录之后，gcc 吐出一个奇怪的错误（之前它确实编译得很好）

make[3]: Entering directory '/home/rd/Desktop/fh/bf4/bbx/o4x/server/server_app/src'
  CXX      main.o
In file included from /usr/include/c++/9/bits/stl_algobase.h:69,
                 from /usr/include/c++/9/memory:62,
                 from /usr/include/c++/9/memory_resource:37,
                 from main.h:5,
                 from main.cpp:1:
./debug/debug.h:14:28: error: variable or field ‘debug_queue_addN’ declared void
   14 | void debug_queue_addN(std::string msg);
      |                            ^~~~~~
compilation terminated due to -Wfatal-errors.

我确实设法通过在所述头文件中包含 < string > 来“解决”该问题，但是出现了一个新的，甚至更奇怪的错误。

make[3]: Entering directory '/home/rd/Desktop/fh/bf4/bbx/o4x/server/server_app/src'
  CXX      main.o
In file included from /usr/include/c++/9/bits/stl_algobase.h:69,
                 from /usr/include/c++/9/memory:62,
                 from /usr/include/c++/9/memory_resource:37,
                 from main.h:5,
                 from main.cpp:1:
./debug/debug.h:14:28: error: variable or field ‘debug_queue_addN’ declared void
   14 | void debug_queue_addN(std::string msg);
      |                            ^~~~~~
compilation terminated due to -Wfatal-errors.

在这一点上，我什至尝试在其他任何地方的任何其他包含之前包含 < algorithm > ，但这根​​本没有帮助。相反，它抛出了这个更奇怪的错误......

现在，有没有人知道为什么会发生这种情况/我能做些什么来解决这个问题？

此外，这是错误输出中提到的代码。

主文件

#include "main.h"
#include "server.h"
#include "config.h"
#include "debug/debug.h"
#include "pidfile.h"
#include "messages.h"

#include <cstring>
#include <iostream>
#include <thread>
#include <algorithm>

主文件

#define __MAIN_H___

#define __cpp_transactional_memory 0
#include <memory_resource>

#endif

调试/调试.h

#ifndef __DEBUG_H__
#define __DEBUG_H__ 1

#include <string> // I added this as a 'solution' to the first mentioned problem
#include "config.h"

#ifdef DEBUGBUILD
#define dbg_out(a) debug_queue_addN(a)
#define dbg_sout(func, msg) this->debug_queue_add(func, msg)
#define dbg_csout(inh, func, msg) debug_queue_addI(inh, func, msg)
#define fatal_err_out(a) std::cout << a

void debug_print();
void debug_queue_addN(std::string msg);
void debug_queue_addI(std::string inh, std::string func, std::string msg);
#else
#define dbg_out(a)
#define dbg_sout(func, msg)
#define dbg_csout(inh, func, msg)
#define fatal_err_out(a) std::cerr << a
#endif

#endif

最后是 Makefile.am

从错误来看，您 似乎debug/debug.h被/usr/include/c++/9/bits/stl_algobase.h. 这与实际相冲突/usr/include/c++/9/debug/debug.h。

至少在我的系统上，这些包含是使用#include <...>表单完成的，即通过搜索系统包含路径。看起来您添加了编译标志，将您的代码也放在该路径上。像 一样无辜的东西-I.，也许？

要解决此问题，您应该摆脱额外的-I标志或重命名您的debug/debug.h文件。
