在Windows上将TagLib编译为Qt C ++项目 [英] Compiling TagLib into Qt C++ Project on Windows

问题描述

我正在使用TagLibSharp在我的旧项目中，我正在尝试从C＃移动，从我的平台边界脱离使用Qt / C ++。但我现在尝试使用这里找到的原始C ++源代码：

http://developer.kde.org/~wheeler/taglib.html

我在一个受伤的世界试图编译到我的应用程序。这个基于Linux的C ++大多数对我来说是愚蠢的，我不知道如何正确地包括这个库到我的项目与Qt。我使用Qt Creator的大部分工作（可能的一切）。

任何人都可以指点我一些有用的教程或指南？任何事情，帮助我了解我甚至与这个源做什么将非常感谢。我对C＃和Windows编程有一个非常透彻的理解，但是我对这些类型的开源项目并没有很好的处理。

谢谢！

现在我已经使用Qt编译TagLib，错误。

* .pro

  INCLUDEPATH + = ../$${TARGET}/taglib-win32 
 LIBS + = -L.. \\ $$ {TARGET} \\taglib-win32
 LIBS + = -llibtag #It似乎想要这是一个* .dll，而不是* .a？ 
 DEFINES + = TAGLIB_NO_CONFIG 
  

* .cpp >

  #include< tag.h> 
 #include< fileref.h> 
 ... 
 //这些都不起作用，即使它们类似于TagLib源中给出的示例。 
 TagLib :: FileRef f（03.flac）; 
 TagLib :: String test = f.tag（） - > album（）; 
 TagLib :: FileName * n = new TagLib :: FileName（test）; 
 TagLib :: FileRef * f = new TagLib :: FileRef（）; 
  

以下是一些确切错误的示例：

  ./ debug\mythread.o：C：\Users\jocull\Documents\My Dropbox\Code\QT\QtTrayTime-build-desktop / ../QtTrayTime/mythread.cpp:20：未定义引用`_imp___ZN6TagLib7FileRefC1ENS_8FileNameEbNS_15AudioProperties9ReadStyleE'
 ./debug\mythread.o:C:\Users\jocull\Documents\My Dropbox\Code\ QT \QtTrayTime-build-desktop /../ QtTrayTime / mythread.cpp：21：未定义引用`_imp___ZNK6TagLib7FileRef3tagEv'
 ./debug\mythread.o:C:\Users\jocull\Documents \My Dropbox \Code\QT\QtTrayTime-build-desktop /../ QtTrayTime / mythread.cpp：42：未定义的引用`_imp___ZN6TagLib6StringD1Ev'
 ./debug\mythread.o:C： \Users\jocull\Documents\My Dropbox\Code\QT\QtTrayTime-build-desktop /../ QtTrayTime / mythread.cpp：42：未定义的引用`_imp___ZN6TagLib7FileRefD1Ev'
 collect2： ld return 1 exit status 
  

使用g ++（Mac / Linux）执行命令行步骤

1. ./ configure --enable-shared = false --enable-static = true


2. make


3. ？没有* .a或* .lib档案建立

解决方案

a href =http://joelverhagen.com/blog/2010/11/how-to-compile-taglib-on-windows/ =nofollow>此信息。我已经概述了如何通过Windows 7 QtCreator编译TagLib。

I am currently trying to make the move from C# and break free from my platform boundaries by using Qt / C++.

I was using TagLibSharp in my old project, but I'm now trying to use the original C++ source found here:

http://developer.kde.org/~wheeler/taglib.html

I am in a world of hurt trying to compile this into my application. Most of this Linux based C++ is gibberish to me and I don't know how to properly include this library into my project with Qt. I'm using Qt Creator for the bulk of my work (everything I possibly can).

Can anyone please point me to some helpful tutorial or guides? Anything to help me understand what I am even doing with this source would be greatly appreciated. I have a very thorough understanding of C# and Windows programming, but I don't exactly have a good handle on what I'm doing with these types of open source projects.

Thanks!

EDIT - THE ANSWER IS HERE I decided to post another question that was a bit more refined for it.

Some older edits...

I now have TagLib compiled with Qt, but am running into "Undefined reference" errors.

*.pro

INCLUDEPATH += ../$${TARGET}/taglib-win32
LIBS += -L"..\\$${TARGET}\\taglib-win32"
LIBS += -llibtag #It seems to want this to be a *.dll, not a *.a?
DEFINES += TAGLIB_NO_CONFIG

*.cpp

#include <tag.h>
#include <fileref.h>
...
//None of these work, even though they are similar to examples given in TagLib source.
TagLib::FileRef f("03.flac");
TagLib::String test = f.tag()->album();
TagLib::FileName *n = new TagLib::FileName("test");
TagLib::FileRef *f = new TagLib::FileRef();

Here are some examples of the exact errors:

./debug\mythread.o:C:\Users\jocull\Documents\My Dropbox\Code\QT\QtTrayTime-build-desktop/../QtTrayTime/mythread.cpp:20: undefined reference to `_imp___ZN6TagLib7FileRefC1ENS_8FileNameEbNS_15AudioProperties9ReadStyleE' 
./debug\mythread.o:C:\Users\jocull\Documents\My Dropbox\Code\QT\QtTrayTime-build-desktop/../QtTrayTime/mythread.cpp:21: undefined reference to `_imp___ZNK6TagLib7FileRef3tagEv' 
./debug\mythread.o:C:\Users\jocull\Documents\My Dropbox\Code\QT\QtTrayTime-build-desktop/../QtTrayTime/mythread.cpp:42: undefined reference to `_imp___ZN6TagLib6StringD1Ev' 
./debug\mythread.o:C:\Users\jocull\Documents\My Dropbox\Code\QT\QtTrayTime-build-desktop/../QtTrayTime/mythread.cpp:42: undefined reference to `_imp___ZN6TagLib7FileRefD1Ev' 
collect2: ld returned 1 exit status 

Command line steps using g++ (Mac/Linux)

1. ./configure --enable-shared=false --enable-static=true
2. make
3. ??? No *.a or *.lib files created
