I think flac-dev is the perfect place for questions about building flac. But the answers are probably going to be geared towards the FLAC point of view rather than the Xcode point of view. > I pulled the latest source code from the SVN repo along with all > the external dependencies including FLAC.

The flac sources are distributed in a configuration that is designed primarily for building from the command-line. I seem to recall that there might have been an Xcode project in there at some point, but if there was, it never worked well. In all honesty, I may be getting confused with some other open source project on that last point. In any event, if you want to compile flac on OSX, then just use Terminal.app Frankly, if you want to compile flac in Xcode, and you're getting mysterious errors, then it's probably a good sign this is a task better left to the experts. It would be great if someone could set this up, but it's not necessary since the command line is available. I've been using Xcode since it was called ProjectBuilder, and I know the environment quite well. However, I have found that it's usually more work than anticipated to convert a command-line build environment to a GUI Xcode environment. It certainly should be simple, but it's probably not really worth anyone's time. That said, if anyone does get it working, please share your Xcode project files so that Josh can hopefully incorporate them into the source release. As for my OSX applications which use FLAC, I always add libFLAC.a to my project, as compiled and installed by the command-line makefile. In other words, rather than compiling the entire source for flac into my applications, I simply link to the library. I have not used the libFLAC++.a because I prefer not to mix Objective C and C++, but I can confirm that the Standard C libFLAC.a works perfectly fine for encoding and decoding FLAC files using the standard API. By the way, I created an Installer.app package which installs the entire flac command-line tools and libraries into appropriate directories, and then you can just link your OSX applications to the precompiled library. This is the OSX package that is available via links at flac.sourceforge.net Brian Willoughby Sound Consulting _______________________________________________ Flac-dev mailing list [email protected] http://lists.xiph.org/mailman/listinfo/flac-dev
