Compiling on Windows about jni-rs

[fasihrana]

OK, I reinstalled Rust from its offline installer. After that the program was correctly complaining about jvm.dll not found. Then it complained about not finding jvm.lib when linking. That was fixed by adding a build.rs file with just the following:

fn main(){
        if cfg!(target_os = "windows") {
                println!(r"cargo:rustc-link-search=c:\Path\to\jdk\lib\");
        }
}

So, now I'm getting errors when I execute the binary compiled complaining that the jvm.dll could not be found even though the directory is in Path.

The reason is that in Powershell "set PATH" doesn't really have any effect.

Had to export the path as $env:Path = $env:Path + "\path\to\jvm.dll"

The error message is wrong: on windows it looks for jvm.dll (see here).

Have you set JAVA_HOME? Do you have jvm.dll somewhere in it?

The build script looks for jvm.dll in all the subdirectories of the path specified in the JAVA_HOME environment variable.

You should add a directory with jvm.dll into the PATH environment variable.

I have specified JAVA_HOME and the jvm.dll is in %JAVA_HOME%\jre\bin\server.
