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++动态链接库的一些函数。当我试图构建我的动态链接库时，我得到一个弹出消息，告诉我'javaw.exe‘的调试信息找不到，或者找不到或者打开不了pdb文件。我已经设置了我的环境变量。这是正常的吗?如果不是，有没有办法避免它？

Answer 1

是的，这是正常的。

Visual Studio只是告诉你，它找不到在调试时显示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(你不需要源代码，因为如果有问题，发现bug的可能性是在你的代码中，而不是甲骨文的代码中)。
