Dear List,
This is my first time posting. I appologize in advance in this is a common
question.
For several days now I have been trying without much success to create a very
basic audio unit. The end result no matter how I have tried ends up with a
linker error. Usually this one:
----
DynamicLibrary.LinkUsingFileList
/Users/rfergu/AUFlanger/build/AUFlanger.component/Contents/MacOS/AUFlanger
/usr/bin/g++-3.3 -o
/Users/rfergu/AUFlanger/build/AUFlanger.component/Contents/MacOS/AUFlanger
"-L/Users/rfergu/AUFlanger/build" "-F/Users/rfergu/AUFlanger/build" -filelist
/Users/rfergu/AUFlanger/build/AUFlanger.build/AUFlanger.build/Objects-normal/LinkFileList
"-framework" "CoreServices" "-framework" "AudioUnit" "-framework" "CoreAudio"
"-arch" "ppc" "-bundle" "-bundle"
ld: Undefined symbols:
vtable for AUFlanger
..failed DynamicLibrary.LinkUsingFileList
/Users/rfergu/AUFlanger/build/AUFlanger.component/Contents/MacOS/AUFlanger ...
---
XCode is an unfamilar IDE to me. I have tried including files, writing code,
and setting the compiler settings from scratch. I used the "Legacy: bundle"
target. I have also tried copying the "SampleEffect" AU project
file/derivatives and changing all the information inside. Further I downloaded
a "ping-pong" example which led me to the exact same ends.
I do know that in my "Project Symbols" (which seem to be organized by indexing
feature) are not the same as in the example code. I do not know why this is,
because the code is *exactly* the same except for changing the name to
AUFlanger and some very minor difference in DSP (I'm trying to implement just a
basic flanger).
Can anyone tell me:
1) What is the best way to begin writing an effect AU?
2) What is the proper target?
3) What are the proper compiler settings if they vary from the SampleEffect
example?
4) Are there any additional ways to clarify linker issues in XCode?
Any assistance, links, or swift kicks in the ass will be greatly apperciated.
Kind Regards,
Robert Ferguson
