error: variable has incomplete type 'const struct oauth_service'

Hello, I'm a developer with the MacPorts project, discovering that bitlbee 3.2.2 does not build for me:

and so forth. I'll attach the full log.

The compiler being used is the one Apple provides with their Xcode development environment:

Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn)
Target: x86_64-apple-darwin13.3.0
Thread model: posix

Weird, it's like oauth.h is missing, only that file. I tried compiling with clang 3.4.2 on linux, it works fine.

Post contents of Makefile.settings?

[Ryan Schmidt <bitlbee@…>]

Aha! Thanks for the hint. I had a different file /opt/local/include/oauth.h (from liboauth 1.0.1) that was interfering. Temporarily deactivating liboath allowed bitlbee to build.

Oh, well, that answers it. We really should unfuck the way we include headers. I saw in your portfile that there's a conflict with libproxy too.
