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:
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

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'

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

应该是什么我确实解决了这个问题并开始使用TagLib?
