libliveMedia 在鏈接 __imp_XXXXXX 時拋出未定義的引用錯誤

Question

我正在嘗試將我的程序編譯為 Windows x64（來自 x32） 在我構建了我需要的所有依賴項和庫之后，我收到以下錯誤：

這是Code::Blocks使用的命令：

g++.exe -o bin\Debug\OpenTextProjector.exe obj\Debug\libraries\base64.o obj\Debug\libraries\tinythread.o obj\Debug\main.o obj\Debug\ScreenSource.o   -lopengl32 -lglu32 -lwinmm -lgdi32 -lwsock32 -lws2_32 libraries\libglfw3.a libraries\libglfw3dll.a libraries\libopengl32.a libraries\libws2_32.a libraries\libglew32.a libraries\libglew32.dll.a libraries\libswscale.dll.a libraries\libavutil.dll.a libraries\libavcodec.dll.a libraries\libfreetype.dll.a libraries\libfreetype.a libraries\libliveMedia.a libraries\libgroupsock.a libraries\libBasicUsageEnvironment.a libraries\libUsageEnvironment.a

您現在可能已經知道，我正在使用 MinGW 進行編譯 (MSYS2)。

以下是一些其他命令的 output 可能會幫助您更好地理解問題：

如果您對代碼感興趣，可以在這里找到我的 GitHub 存儲庫。

我已經嘗試了來自 inte.net 的許多修復程序，但我仍然不明白為什么我會遇到這個問題。 任何幫助將不勝感激。 謝謝！

Answer 1

經過幾個小時的研究，我只是以錯誤的順序添加了庫…… ws2_32庫應該是最后一個。 這是命令：

g++.exe  -o bin\Debug\OpenTextProjector.exe obj\Debug\libraries\base64.o obj\Debug\libraries\tinythread.o obj\Debug\main.o obj\Debug\ScreenSource.o   -lopengl32 -lglu32 -lwinmm -lgdi32 libraries\libglfw3.a libraries\libglfw3dll.a libraries\libopengl32.a libraries\libglew32.a libraries\libglew32.dll.a libraries\libswscale.dll.a libraries\libavutil.dll.a libraries\libavcodec.dll.a libraries\libfreetype.dll.a libraries\libfreetype.a libraries\libliveMedia.a libraries\libgroupsock.a libraries\libBasicUsageEnvironment.a libraries\libUsageEnvironment.a -lws2_32 -lssl -lcrypto

如您所見，我添加的最后一個庫是產生錯誤的庫。 所以對於任何遇到同樣問題的人：檢查你的庫的順序！
