Shared lib build output

[zuck]

Hi, when I try to build a shared lib with QMake (on Linux) I obtain 4 output files:

libxxx.so
libxxx.so.1
libxxx.so.1.0
libxxx.so.1.0.0

libxxx.so
libxxx.so.1
libxxx.so.1.0
libxxx.so.1.0.0

To copy to clipboard, switch view to plain text mode 

This is the .pro file:

TARGET = test
TEMPLATE = lib
CONFIG += shared dll
DEFINES += TEST_LIBRARY
SOURCES += test.cpp
HEADERS += test.h\
        test_global.h

TARGET = test
TEMPLATE = lib
CONFIG += shared dll
DEFINES += TEST_LIBRARY
SOURCES += test.cpp
HEADERS += test.h\
        test_global.h

To copy to clipboard, switch view to plain text mode 

The global define header:

#ifndef TEST_GLOBAL_H
#define TEST_GLOBAL_H
 
#include <QtCore/qglobal.h>
 
#if defined(TEST_LIBRARY)
#  define TESTSHARED_EXPORT Q_DECL_EXPORT
#else
#  define TESTSHARED_EXPORT Q_DECL_IMPORT
#endif
 
#endif // TEST_GLOBAL_H

#ifndef TEST_GLOBAL_H
#define TEST_GLOBAL_H

#include <QtCore/qglobal.h>

#if defined(TEST_LIBRARY)
#  define TESTSHARED_EXPORT Q_DECL_EXPORT
#else
#  define TESTSHARED_EXPORT Q_DECL_IMPORT
#endif

#endif // TEST_GLOBAL_H

To copy to clipboard, switch view to plain text mode 

And the very trivial exported class declaration:

#ifndef TEST_H
#define TEST_H
 
#include "test_global.h"
 
class TESTSHARED_EXPORT Test {
public:
    Test();
};
 
#endif // TEST_H

#ifndef TEST_H
#define TEST_H

#include "test_global.h"

class TESTSHARED_EXPORT Test {
public:
    Test();
};

#endif // TEST_H

Is it normal?

I'd say so, yes. Having multiple files detailing the version more and more allows your applications to choose how closely they want to follow the libraries versions.

Ok, thanks
