Thanks for the reply, j o a r.
What warnings, if any, do you get when compiling?
I don't get warnings when ZeroLink is on or when it's off. I did get
a warning about missing lidib in the programmer's home folder before
I removed that entry from the path. However, I assume the entry
wasn't necessary because there was already an entry to libid3 in the
project folder.
The search paths used to include an entry to an id3lib folder in
the programmer's home directory in addition to the previous
entries I mentioned. Why is this? Also in the main target (there's
only one), under "Link Binary With Libraries", there were two
entries for libid3.dylib with the exact same file locations (the
project folder). Why Would Xcode need to link the exact same
library twice?
What happens if you remove / change these settings?
I tried both and still experience the same crash. First I removed the
path entry to the programmer's id3lib folder, then I also removed the
second link entry for id3lib.dylib. I did a build and run after each
removal and got the same crash.
Another complication is that I have a copy of id3lib with the same
version in my /sw tree. However, when I do a binary compare of the
dylib in /sw and the one in my project folder, they have numerous
differences. Could ZeroLink be loading one library while the Xcode
linker loads another?
That should be easy to verify, don't you agree?
Urm... Yes I think it should be easy to verify except I haven't the
slightest idea how. Is there a tool that will show me which library a
running binary is using? I tried renaming libid3.dylib to
libid3.dylib.old in /sw/lib, cleaned all, and then rebuilt with and
without ZeroLink with the same results as I described before.
Thanks for the help though, j o a r, at least we have some
possibilities eliminated.
Peter
