Hi. getting started with K/N. Trying to create an interop lib for libFUSE. Def file:

headers fuse3/fuse_lowlevel.h
compilerOpts = -lfuse3

when i run cinterop as such:

cinterop -def libfuse.def -copt -I/usr/include -o libfuse

I get this error:

Exception in thread "main" java.lang.Error: /usr/include/fuse3/fuse_lowlevel.h:22:2: error: FUSE_USE_VERSION not defined
	at org.jetbrains.kotlin.native.interop.indexer.UtilsKt.ensureNoCompileErrors(Utils.kt:137)

	at org.jetbrains.kotlin.cli.utilities.MainKt.main(main.kt:29)

This is normal when a

#define FUSE_USE_VERSION 31

does not appear before the header is included. Is there anyway I can do this? I tried adding the

---

and putting the define after that, but the docs indicate that this is for adding stuff AFTER the headers have been processed. Is there a way to add something before the headers?

try adding something like -DFUSE_USE_VERSION=31 to compilerOpts
