原本以為這麼常用的功能應該是標準C支援的，試了一下才發現不同平臺差異挺大。

參考部落格：https://blog.csdn.net/u012005313/article/details/50687297

上程式碼

test_dir.cpp

#include <vector>
#include <algorithm>
#include <iostream>
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <string>

#ifdef linux
#	include <unistd.h>
#	include <dirent.h>
#else
#	include <direct.h>
#	include <io.h>
#   define getcwd _getcwd
#endif
using namespace std;

vector<string> getFiles(string path)
{
	vector<string> files;
	string p;
#ifdef _WIN32
	_finddata_t file;
	long lf;
	if ((lf=_findfirst(p.assign(path).append("\\*").c_str(), &file)) == -1) {
		cout<<path<<" not found!!!"<<endl;
	} 
	else 
	{
		do {
			//cout<< file.name <<endl;
			if (strcmp(file.name, ".") == 0 || strcmp(file.name, "..") == 0)
				continue;
			files.push_back(p.assign(path).append("\\").append(file.name));
		}
		while(_findnext(lf, &file) == 0);
	}
	//cout << "bye" << endl;
	_findclose(lf);
#endif
 
#ifdef linux
	DIR *dir;
	struct dirent *ptr;
	char base[1000];
 
	if ((dir=opendir(path.c_str())) == NULL)
        {
		perror("Open dir error...");
                exit(1);
        }
 
	while ((ptr=readdir(dir)) != NULL)
	{
		if(strcmp(ptr->d_name,".")==0 || strcmp(ptr->d_name,"..")==0)    ///current dir OR parrent dir
		        continue;
		else if(ptr->d_type == 8)    ///file
			files.push_back(p.assign(path).append("/").append(ptr->d_name));
		else if(ptr->d_type == 10)    ///link file
			continue;
		else if(ptr->d_type == 4)    ///dir
			continue;
	}
	closedir(dir);
#endif
 
	sort(files.begin(), files.end());
	return files;
}

int main(void)
{
	char current_address[500] = {0};
	getcwd(current_address, 500); 
	cout<<"[begin] " << current_address<<endl;
	vector<string> files = getFiles((string)current_address);
	
	for (int i=0; i<files.size(); i++)
	{
		cout<<files[i]<<endl;
	}
 
	cout<<"[end]..."<<endl;
	return 0;
}
 

在linux的makefile

CC=g++
test_dir: test_dir.cpp
	$(CC) test_dir.cpp -o test_dir

all: test_dir

Window下的nmake檔案

CFLAGS = -nologo -O2 -MD -I.
SRCS = .\test_dir.cpp
test_dir.exe: $(SRCS)
	cl $(CFLAGS) [email protected]  $**
	del *.obj
	
all: test_dir.exe

clean:
    del /Q *.exe *.obj *.manifest
 

編譯執行都沒問題
