Question

我正在努力创建一个程序，该程序使用正在进行的项目的C ++编程将歌曲歌词嵌入* .mp3文件中。搜索之后，我发现了一个名为“ TAGLIB”的库，该库可以处理ID3v2.3标准元数据。根据LIBTAG安装指南，我运行CMAKE并配置为this image和this image，并使用mingw

进行构建。

C:\Desktop\taglib> mingw32-make 和 C:\Desktop\taglib> mingw32-make install

我得到的文件夹C:\Program Files (x86)\taglib中包含内容，包括

bin\libtag.dll
bin\libtag_c.dll
bin\libtag_c.dll

include\*.h files

lib\pkgconfig\taglib.pc
lib\pkgconfig\taglib_c.pc
lib\libtag.a
lib\libtag.dll.a
lib\libtag_c.dll.a

在代码块中，我链接了libtag.a，libtag.dll.a和libtag_c.dll.a，并将搜索目录配置为C:\Program Files (x86)\taglib，并且对当前项目也是如此。但是编译器会多次出现此类错误

undefined reference to _imp___ZN6TagLib6StringC1EPKcNS0_4TypeE'|

当我尝试编译库提供的示例代码时。

然后我用GCC来编译代码。但是这次没有运气了。

C:\Program Files (x86)\taglib>gcc -o f.exe framelist.cpp -L"C:/Program Files (x86)/taglib/lib/" -libta.a -I"C:/Program Files (x86)/taglib/include/taglib"

出现此错误：

如您所知，我是新增外部库的新手，可以帮助我弄清楚如何正确安装“ LIBTAG”以开始在代码块中进行编码。

如何在代码块中构建和安装TAGLIB
