What library to link to on Windows 7 for JNI_CreateJavaVM?

Question

I am building a first working version of a JNI application in C++. I do not believe the specific details of the application are important for this question. If they are, I will append them.

My code compiles without error. However, there is a single linker error:

error LNK2019: unresolved external symbol __imp__JNI_CreateJavaVM@12

I understand that JNI_CreateJavaVM is not included in jvm.lib / jvm.dll . However, I cannot determine what library I do need to link to for this function.

I have JDK installed (but only 64-bit - and this is a 32-bit C++ application, which may be relevant).

Can somebody please assist?

Steps to link the jvm.lib to your project in Visual Studio:

• Right click on the project -> properties.
• On the Properties dialog box, add jvm.lib under Linker->Input->AdditionalDependencies area.
• Lastly write jvm.lib path(like "C:\\Program
  Files\\Java\\jdk1.7.0_60\\lib") under
  Linker->General->AdditionalLibraryDirectories

After those steps, your project can link to jvm and work well.

如果要从C ++运行Java应用程序，我建议使用exec并创建一个新的进程esp（如果一个是32位，另一个是64位）。
