Compilation failure in JNativeHook

Question

Trying to compile this https://github.com/kwhat/jnativehook/wiki/Compiling

made it as far as the step where I have to run ant all to build.

Compile fails with the following in command prompt.

    [javac] Fatal Error: Unable to find package java.lang in classpath or bootcl
asspath

BUILD FAILED
C:\Users\George\Downloads\sounds\JNativeHook-2.0.1\JNativeHook\build.xml:394: Co
mpile failed; see the compiler error output for details.

EDIT: I just copied the rt file into the directory i'm trying to compile. I got past the first error but now I'm getting

Still diligently trying to figure this out in the mean time.

Update:

I think I've been going about this wrong. I tried doing this inside MINGW64 which is probably how I should have been doing it.

Sadly still get an error I'm looking into.

compile-java:
     [echo] Compiling Java source...

UPDATE:

Wow so how many shells does msys64 have. I've now tried what seems to be the last and final shell msys2_shell.bat and its gotten even further but still fails.

Now I get

So close.

UPDATE:

Installed clang and now get this detailed error from the config.log file.

Answer 1

Ok so for future JNativeHook compiler noobies like myself doing this on windows 8.1 here is what I had to do to get this working.

Aside from following all the steps in the compile for windows section provided on their git.

You also need to...

Download LLVM for windows. Copy your rt.jar into the JNativeHook directory. And make sure absolutely make sure that you've deleted any build.properties generated from failed builds.

That should get it working.

Answer 2

Dont forget to run ant distclean first if you are trying to compile 2.0.1. I botched the package process by forgetting to include the build.properties file in the exclude list for the zip file. I think that will also fix your rt.jar copying issue. It may solve all of your issues ;) Anyway, 2.0.2 will fix the problem and is scheduled for release on Sunday.
