JNAerator fails to output anything after hours of processing a simple header

[MayaPosch]

I tried to use JNAerator to create a JNA binding for a simple library that has the following header: https://github.com/MayaPosch/NymphCast/blob/master/src/client_lib/nymphcast_client.h

Under MSYS2 Bash, I ran the following command:

java -jar /e/Projects/testing/JNAerator/jnaerator/target/jnaerator-0.13-SNAPSHOT-shaded.jar -library nymphcast_jna nymphcast_client.h -o . -v -mode StandaloneJar

Output:
