JNI unresolved external symbol __imp_JNI_CreateJavaVM in a 64-bit compiler

Question

I am trying to create a JVM usin JNI. I am using win 7 64-bit OS. On the JNI_CreateJavaVM line, my program crashes. I decided to compile my program using a 64-bit compiler and received the following error:

Error 1 error LNK2001: unresolved external symbol __imp_JNI_CreateJavaVM

Where should I start looking for a binding problem and why does my program crashes in 32-bit mode?

 void createJVM() { JavaVMInitArgs vm_args; JavaVMOption options[4]; int n = 0; char * str; str= new char[1000]; sprintf(str, "-Djava.class.path=%S\\tst.jar", myPath); options[n++].optionString = str; str= new char[1000]; sprintf(str, "-Djava.library.path=%S\\lib;%S", myPath, myPath); options[n++].optionString = str; str= new char[1000]; sprintf(str, "-Duser.dir=%S", myPath); options[n++].optionString = str; vm_args.version = JNI_VERSION_1_4; vm_args.nOptions = n; vm_args.options = options; vm_args.ignoreUnrecognized = false; JNI_CreateJavaVM(&jvm, (void**)&env, &vm_args); } 

Answer 1

Have you added 'jvm.lib' as an additional dependency in your project? in addition, you need to specify the location of jvm.lib in additional library directories ...

also note that for a 64-bit application you need to point to a 64-bit library, otherwise the linker will not link to

These parameters can be found in the "Configuration Properties →" area.

Hope this information helps you.

Since I cannot calculate (even less than 15 reputations), I just want to confirm that the Naytzyrhc solution worked for me.

To clarify this a bit, in Visual Studio Express 2013 (v12) you should go to:

 Project -> [YourProjectName] Properties... -> Linker -> General -> Additional Library Directories 

to add the lib folder to additional library directories and:

 Project -> [YourProjectName] Properties... -> Linker -> Input -> Additional Dependencies 

to add jvm.lib to additional dependencies.
