我不想編譯動態庫,所以this question沒有用。如何編譯Windows的靜態Taglib庫?
我下載標籤庫和使用編譯它:
cmake -DENABLE_STATIC=ON -DENABLE_STATIC_RUNTIME=ON -DWITH_MP4=ON -G "Visual Studio 10"
這產生了Visual Studio的解決方案,我可以編譯「標籤」項目,該項目產生tag.lib中的taglib /釋放。
問題是當我嘗試使用該庫在測試應用程序 - 沒什麼,只是一個簡單的測試:
#include "stdafx.h"
#include "fileref.h"
int _tmain(int argc, _TCHAR* argv[])
{
TagLib::FileRef d("");
return 0;
}
我得到以下鏈接錯誤:
Error 1 error LNK2001: unresolved external symbol "__declspec(dllimport) public: virtual __thiscall TagLib::FileRef::~FileRef(void)" ([email protected]@@[email protected]) C:\...\taglib_test\taglib_test\taglib_test.obj taglib_test
Error 2 error LNK2001: unresolved external symbol "__declspec(dllimport) public: __thiscall TagLib::FileRef::FileRef(class TagLib::FileName,bool,enum TagLib::AudioProperties::ReadStyle)" ([email protected]@@[email protected]@[email protected][email protected]@[email protected]@Z) C:\...\taglib_test\taglib_test\taglib_test.obj taglib_test

Error 5 error LNK1120: 4 unresolved externals C:\...\taglib_test\Release\taglib_test.exe taglib_test
有人能請給我一個關於這裏發生了什麼的想法?
以下是預處理器在標籤項目定義:
WIN32
_WINDOWS
NDEBUG
HAVE_CONFIG_H
_CRT_SECURE_NO_DEPRECATE
_CRT_NONSTDC_NO_DEPRECATE
TAGLIB_STATIC
CMAKE_INTDIR="Release"
