無法找到程序入口點？

Question

我遇到了一個奇怪的問題。 更新到最新的ffmpeg headers / lib / dll后，我不斷收到錯誤：

The procedure entry point __glewProgramUniform1i could not be located in the dynamic link library

如果我改變，以便我使用靜態鏈接鏈接到glew，那么該特定錯誤消失，而是在其他一些dll中抱怨其他一些過程入口點，依此類推。

一旦恢復到舊的ffmpeg headers / lib / dll，問題就會消失。

什么可能導致這種行為？ 我該如何調試？

注意：這僅在發布版本期間發生，而不是在調試版本期間發生。

您很可能已更新.h和.lib文件，但鏈接到過時的DLL。 確保程序鏈接到的DLL是與.h和.lib文件匹配的DLL。

您可以通過在配置文件模式下運行Dependency Walker來調試程序加載時發生的情況。 這將顯示實際加載的DLL的完整路徑，然后您將能夠找出出錯的地方。
