Troubleshooting

Overview

• When I start the program I get the error: "Cannot find 'jvm.dll'"!
• When I start the program I get the error: "Cannot find 'libjvm.so'"!
• I get an error like: "Unresolved symbol main or undefined reference main"!

When I start the program I get the error: "Cannot find 'jvm.dll'"!

In Windows you have to append to the path of the file "jvm.dll" to your system or user environment path variable. The file is in a subfolder of the JRE installation directory.

When I start the program I get the error: "Cannot find 'libjvm.so'"!

In Linux you have to append the path of the file "libjvm.so" to your "ld.so.conf" file (for more information see the manual of your distribution). The file is in a subfolder of the JRE installation directory. If you are not sure how to do that, please have a look in the documentation of your distribution!

I get an error like: "Unresolved symbol main or undefined reference main"!

If you get an error like:

error LNK2001: unresolved external symbol _main
undefined reference to `WinMain@16'

you probably tried to compile only the library. The problem is that the linker can not find the main entry point of the program. So make sure you have a main function in your program, because the library does not have one.
