我试图创建一个使用TagLib库的项目。我不确定如何去做。我已经下载TagLib 1.11.1如何在Qt项目中包含一个库

我建,如下所示:

构建zlib的,首先有CMake的创建一个Visual Studio解决方案文件,然后建立与Visual Studio这样的解决方案:

的mkdir建立& & cd build cmake .. -G“Visual Studio 14 2015 Win64”-DCMAKE_INSTALL_PREFIX =“e:\ workspace \ lib \ installed” msbuild/P:Configuration = Debug INSTALL.vcxproj 的MSBuild/P:配置=释放INSTALL.vcxproj

建立标签库多以同样的方式:

CD .... \的taglib-1.11.1 的mkdir建立& & CD编译 cmake .. -G“Visual Studio 14 2015 Win64”-DCMAKE_INSTALL_PREFIX =“e:\ workspace \ lib \ installed”-DZLIB_INCLUDE_DIR =“e:\ workspace \ lib \ installed \ include”-DZLIB_LIBRARY =“e:\ workspace \ lib \ installed \ lib \ zlib.lib“-DWITH_ASF = on -DWITH_MP4 = on -DBUILD_EXAMPLES = on msbuild/P:Configuration = Rele ASE INSTALL.vcxproj

我创建一个简单的Qt控制台应用程序:

enter image description here

我再从标签库构建上述E:\workspace\lib\installed\lib使用Qt

的Qt增加tag.lib - > Add Library - > Library Type (External Library) - > .......

main.cpp中:

#include <QCoreApplication> 
#include <QDebug> 

#include <taglib/fileref.h> 

int main(int argc, char *argv[]) 
{ 
    QCoreApplication a(argc, argv); 
    TagLib::FileRef f("D:/Dire Straits - Sultans of Swing.mp3"); 
    return a.exec(); 
} 

taglibtest.pro

QT += core 
QT -= gui 

CONFIG += c++11 

TARGET = taglibtest 
CONFIG += console 
CONFIG -= app_bundle 

TEMPLATE = app 

SOURCES += main.cpp 

win32:CONFIG(release, debug|release): LIBS += -L$$PWD/taglib/builds/ -ltag 
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/taglib/builds/ -ltagd 
else:unix: LIBS += -L$$PWD/taglib/builds/ -ltag 

INCLUDEPATH += $$PWD/taglib/builds 
DEPENDPATH += $$PWD/taglib/builds 

win32:CONFIG(release, debug|release): LIBS += -L$$PWD/taglib/builds/ -ltag 
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/taglib/builds/ -ltagd 
else:unix: LIBS += -L$$PWD/taglib/builds/ -ltag 

INCLUDEPATH += $$PWD/taglib/builds 
DEPENDPATH += $$PWD/taglib/builds 

HEADERS += \ 
    taglib/aifffile.h \ 
    taglib/aiffproperties.h \ 
    taglib/apefile.h \ 
    taglib/apefooter.h \ 
    taglib/apeitem.h \ 
    taglib/apeproperties.h \ 
    taglib/apetag.h \ 
    taglib/asfattribute.h \ 
    taglib/asffile.h \ 
    taglib/asfpicture.h \ 
    taglib/asfproperties.h \ 
    etc.... 
    etc.... 

我收到以下错误,每当我试图建立在Qt的项目:

F:\taglibtest\main.cpp:-1: error: undefined reference to `_imp___ZN6TagLib8FileNameC1EPKc' 

F:\taglibtest\main.cpp:-1: error: undefined reference to `_imp___ZN6TagLib7FileRefC1ENS_8FileNameEbNS_15AudioProperties9ReadStyleE' 

F:\taglibtest\main.cpp:-1: error: undefined reference to `_imp___ZN6TagLib7FileRefD1Ev' 

F:\taglibtest\main.cpp:-1: error: undefined reference to `_imp___ZN6TagLib7FileRefD1Ev' 

:-1: error: release/main.o: bad reloc address 0x0 in section `.ctors' 

:-1: error: final link failed: Invalid operation 

collect2.exe:-1: error: error: ld returned 1 exit status 

应该是什么我确实解决了这个问题并开始使用TagLib?

你编译TagLibzlibVisual Studio和你mingw编译项目(至少这是我从错误消息猜测)。这不起作用。您需要使用相同的编译器编译所有库和应用程序。

Visual Studiogcc有不同ABI是如此gcc无法看到Visual的符号。
