Im binding against a library that is importing Foundation/Foundation.h using cinterop. Should I point out some system path to make this work? Im thinking in includeDirs in the gradle file.

[Kris Wong]

you should use header filters

[Kris Wong]

system headers are already supported

[Alexander Larsson]

Ok so just filter out the headers and it should work?

[Kris Wong]

yep

[Kris Wong]

hopefully the relevant header files have some kind of prefix or something you can use (to include them)

[Alexander Larsson]

Hmm, I don't think this was my issue after all. I'm getting this error:

[Kris Wong]

same fix either way 🙂

[Alexander Larsson]

Line 492 is: @class NSString, Protocol;

[Alexander Larsson]

Is it?

[Kris Wong]

yeah, you don't need it to process those files

[Alexander Larsson]

I have two def files:

headers = openssl/asn1.h openssl/err.h openssl/pkcs12.h openssl/rsa.h openssl/x509.h
headerFilter = openssl/**

[Alexander Larsson]

and

headers = ObjektiveSSL/ObjektiveSSL.h
headerFilter = ObjektiveSSL/** openssl/**

[Alexander Larsson]

So why is it not fitlering?

[Kris Wong]

that's a good question

[Kris Wong]

your filters are correct afaik

[Alexander Larsson]

Hmm ok. Any idea how to debug this?
