JNAerator won't compile any source files

[DevCybran]

Using JNAerator 0.12 on Windows 7 x64 with Visual Studio 2013, I am trying to generate a JAR with bindings for the libsodium library. I am using the following command line: "C:\Program Files\Java\jdk1.8.0_60\bin\java.exe" -jar jnaerator-0.12-shaded.jar -library sodium sodium.h libsodium.dll -mode Jar -preferJavac -runtime JNA > jnaerator.log 2>&1

This is the output JNAerator shows:

Afterwards, no JAR is present. The following files have been created: _jnaerator.choices, _jnaerator.macros.cpp, _jnaerator.normalizedParsed.cpp, _jnaerator.preprocessed.c, _jnaerator.rawParsed.cpp; where _jnaerator.choices is empty.

Using alternative modes or runtimes won't change anything. When using the eclipse compiler, only a usage help page is displayed and nothing compiled either.
