Hi all,

I got some compiling errors when building Celestia from snapshots or CVS.

System: Pentium4, Slackware (current), kernel 2.6.6, X.Org 6.7.0, KDE 3.2.3, gcc 3.3.4, etc ...

*celestia-cvs.20040625.tgz from http://celestia.teyssier.org/download/daily/
compiles with GLUT GUI but does not with KDE:

Same problem with the KDE GUI.

Is there a problem with my installation of KDE or is Celestia's KDE GUI broken in CVS? Note that I can still compile and run smoothly 1.3.1 with KDE GUI.

*CVS checkout from Sourceforge on June 23, 2004:

Code: Select all

astro@lune:~/celestia$ make -f Makefile.cvs
This Makefile is only for the CVS repository
This will be deleted before making the distribution

*** YOU'RE USING automake (GNU automake) 1.8.5.
*** KDE requires automake 1.5
make[1]: *** [cvs] Error 1
make: *** [all] Error 2

Last time I did that was before 1.3.1 was released and it went smoothly,

Thank you.

The QString(std::string) constructor was introduced in Qt 3.1, are you sure you're not using old Qt 3.0 headers?

I am using QT 3.3.2. I specified the directories to find both include files and libraries:

Code: Select all

./configure --with-kde --with-qt-includes=/usr/lib/qt-3.3.2/include --with-qt-libraries=/usr/lib/qt-3.3.2/lib/

but I still get the same error message while running make.

Below is part of my qstring.h.

Code: Select all

class Q_EXPORT QString
{
public:
    QString();                                  // make null string
    QString( QChar );                           // one-char string
    QString( const QString & );                 // impl-shared copy
    QString( const QByteArray& );               // deep copy
    QString( const QChar* unicode, uint length ); // deep copy
#ifndef QT_NO_CAST_ASCII
    QString( const char *str );                 // deep copy
#endif
#ifndef QT_NO_STL
    QString( const std::string& );                   // deep copy
#endif
    ~QString();

    QString    &operator=( const QString & );   // impl-shared copy
    QString    &operator=( const char * );      // deep copy
#ifndef QT_NO_STL
    QString    &operator=( const std::string& );     // deep copy
#endif
    QString    &operator=( const QCString& );   // deep copy
    QString    &operator=( QChar c );
    QString    &operator=( char c );

    QT_STATIC_CONST QString null;

    bool        isNull()        const;
    bool        isEmpty()       const;
    uint        length()        const;
    void        truncate( uint pos );

    QString &   fill( QChar c, int len = -1 );

    QString     copy()  const;

Is

Code: Select all

QString( const std::string& );

the constructor you are talking about? In that case I should maybe track QT_NO_STL.

Thank you.

Yes, you're right. Now I remember we've had this problem before, some distributions use Qt without STL support. You now have to recompile Qt to enable that STL support.
