c++ - 在ubuntu上编译c++项目

Question

我正在编写我的 c++ 项目，在 visual studio 中一切顺利，但是当我在 ubuntu 上编译它时，很多事情都出错了。示例:

int main (int argsNum, char* args[]){
    Country* country = new Country("USA");
    Military* military = new Military("Army",country);
    Shalishut* shalishut = new Shalishut(military);
    Manager* manager = Manager::GetInstance();

    FileReader* fileReader = FileReader::GetInstance();
    fileReader->ReadCityConfig(args,country);
    fileReader->ReadRoadConfig(args,country);
    fileReader->ReadMilitrayCampConfig(args,military);

    military->ShowBases();

    return 0;
}

void FileReader::ReadMilitrayCampConfig(char* args[], Military* military){
    string line;
    char inputFileName [MAX_FILE_NAME_LEN];
    strcpy (inputFileName,args[3]);
    ifstream myfile (inputFileName); //inputFileName
    char* campName;
    string cityName;

    if (myfile.is_open()){
        while (!myfile.eof()){ //until the end of file
            getline (myfile,line); //separate each line.
            if ((line.size() != 0) && (line[0] != '#')) {
                campName = strtok(&line[0],",");
                cityName = (string)strtok(NULL,",");
                Shalishut::FixName(campName);  Shalishut::FixName(&cityName[0]);
                if (!(military->IsBaseExist(campName))){
                    if (military->GetCountry()->IsCityExist(cityName)){
                        Base* baseToAdd = new Base(campName,cityName);
                        if (baseToAdd != NULL){ 
                            military->AddBaseToMilitary(baseToAdd);
                            military->GetCountry()->FindCity(cityName)->AddBaseToCity(baseToAdd);
                        }
                    }
                    else cout << "ERROR: City named \"" << cityName << "\" does not exist, can't add base \"" << campName << "\" !" << endl<<endl;
                }
                else cout << "ERROR: Base Named \"" << campName << "\" is already exist in Military, can't create base!" << endl<<endl;
            }       
        }
        myfile.close();
    }
    else throw ExceptionMilitaryCampConfigFileFault(); /*cout << "ERROR: Unable to open MilitaryConfig file!"<< endl;*/
}

bool Country::IsCityExist(const string cityName){
    map<string ,City*>::iterator itCities;
    itCities = m_cities.find((string)cityName);
    if (itCities != m_cities.end()) return true;
    else return false;
}

void Shalishut::FixName(char* name){
    int i;
    name[0] = toupper(name[0]);
    for (i=1 ; name[i] ; i++){
            name[i] = tolower (name[i]);
        }
    }
}

问题是程序读取了城市和道路，但是当它读取军营时我得到了:

" does not exist, can't add base "Hazerim" !

即使在配置文件中我有相同名称的基础。提醒:在 visual studio 中它完美运行!

Answer 1

假设错误消息实际上是 错误:名为 _____ 的城市不存在，无法添加基数“Hazerim” 我会仔细查看城市和城市的大写/拼写 -以您的输入为基础。它们可能不匹配。

还在 std::string 上使用 strtok 只是自找麻烦，因为它具有破坏性，并且字符串不希望它们的内部状态被随机破坏。 find_first_of 等方法可以帮助您解析 C++ 字符串。
