Agreed. I started with OF few weeks ago and the first days to get GUI plugins working probably cost me 3 years of my life.
Anyway, cleaned up my addons/examples folder of anything syphon related.
1) Got the zip from https://github.com/astellato/ofxSyphon
2) Unzipped, copy pasted the whole thing into my addons folder.
3) Grabbed the example in the unzipped folder and copy pasted it into my examples/addons folder
4) Error when compiling:
clang: error: no such file or directory: ‘/System/Library/Frameworks/Carbon.framework/Headers/Carbon.h’
clang: warning: -lpthread: ‘linker’ input unused
Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 1
Working on 10.8, xcode 4, OF 7.0.4
