Piszę w Qt coś jak menadżer plików *.ini wszystko jest zamknięte w klasie:
namespace FNC
{
class IniFile
{
public:
IniFile();
void Open( QString FileName );
void Save( QString FileName );
QString GetValue( QString Section, QString Key );
void WriteValue( QString Section, QString Key, QString Value = "=EMPTY=");
QString GetSectionsNames( QString separator );
QString GetKeysNames( QString Section, QString separator );
private:
QStringList Sections;
QStringList Keys;
QStringList Values;
QString EMPTY();
};
}
a to definicje funkcji:
using namespace FNC;
QString ini(QString c)
{
return FNC::Coder::Text2FNI( c, FNC::Ini );
}
IniFile::IniFile()
{
}
void IniFile::Open( QString FileName )

if( !file.open( QIODevice::ReadOnly | QIODevice::Text ) ) return;
QTextStream ts(&file);
QString line, lastSection;
for(; line != "end"; line = FNC::Coder::FNI2Text( ts.readLine(), FNC::Ini ) )
{
if(line.isEmpty()) continue;
if(line[0] == '#') continue;
if( line[0] == '[' )
{
line.remove( QChar('['), Qt::CaseInsensitive );
line.remove( QChar(']'), Qt::CaseInsensitive );
Sections << line;
lastSection = line;
Keys << EMPTY();
Values << EMPTY();
}
else
{
line.replace( QString("="), QString(" ") );
QStringList podzial = line.split( QRegExp("\\W+"), QString::SkipEmptyParts );
Sections << lastSection;

}
line.clear();
}
}

for( int i = 0; i < Sections.size(); ++i )
{
if( Sections.at(i) != LastSection )
{

}
else

}
}

open.close();
}

{

{

{

Values.insert( (i-1), Value );
}
}
}
else
{

QString LastSection = Sections.at(0);
int i = 0;
for( ; i < ( Sections.size()+1 ); ++i )
{

QString IniFile::GetSectionsNames(QString separator)
{
return Sections.join( separator );
}
QString IniFile::GetKeysNames(QString Section, QString separator)

Wiem że są tutaj niepotrzebne funkcje i wgl ale po prostu chce nauczyć sie używania klas. Mój problem polega na tym że kiedy wywołuje w projekcie
FNC::IniFile ini;
ini.Open("Ini.ini");
itd. To zawsze wyrzuca mi błędy:
'C:\Users...\manager.cpp:-1: błąd: undefined reference to
FNC::IniFile::IniFile()' 'C:\Users\...\manager.cpp:-1: błąd: undefined reference toFNC::IniFile::Open(QString)'
'C:\Users...\manager.cpp:-1: błąd: undefined reference toFNC::IniFile::GetSectionsNames(QString)' 'C:\Users\...\manager.cpp:-1: błąd: undefined reference toFNC::IniFile::GetValue(QString, QString)'
'C:\Users...\manager.cpp:-1: błąd: undefined reference toFNC::IniFile::GetValue(QString, QString)' ':-1: błąd: release/manager.o: bad reloc address 0x20 in section.text$_ZN7QStringD1Ev[__ZN7QStringD1Ev]'
'collect2.exe:-1: błąd: error: ld returned 1 exit status'
I nie ważne w jakim środowisku piszę (Code::Blocks, Qt Creator) to zawsze wyrzuca mi te błędy. Nagłówki są dołączone, prubowałem z
extern "C" { /*...*/ }
ale też nie działa :c
