java - 找不到 javaw.exe pdb

Question

我正在构建一个 java 应用程序，它使用 jni 调用 c++ dll 的某些函数。当我尝试构建我的 dll 时，我收到一个弹出消息，提示找不到或不匹配“javaw.exe”的调试信息。无法找到或打开 pdb 文件。我已经设置了我的环境变量。这是正常的，如果不是有没有办法避免它？

Answer 1

是的，这很正常。

Visual Studio 只是说你在调试时找不到显示 C++ 源代码所需的 pdb 文件——但不是你的源代码，而是 javaw.exe 本身的源代码（你不需要，如果有的话是问题，发现错误的可能性在您的代码中，而不是在 Oracle 中是相当大的）。
