I've run into a problem updating one of my apps for Leopard. I'm
able to compile and run on Leopard, but when run on Tiger the app is
crashing:
Host Name: XXX
Date/Time: 2007-10-31 16:04:40.871 -0700
OS Version: 10.4.10 (Build 8R2232)
Report Version: 4
Command: Play
Path: /Volumes/BOOTH/Play.app/Contents/MacOS/Play
Parent: WindowServer [56]
Version: 0.2 (1050)
PID: 791
Thread: Unknown
Link (dyld) error:
Library not loaded: /usr/lib/libcurl.4.dylib
Referenced from: /Volumes/BOOTH/Play.app/Contents/MacOS/Play
Reason: image not found
Obviously the problem is that on Leopard curl has been updated, while
on Tiger the latest curl available is libcurl.3. After reading the
cross-development programming guide I've set the SDK to 10.5 and the
deployment target to 10.4, as I want to have Leopard features
available but the app should run on Tiger. Other than adding -lcurl
to the other linker flags everything is fairly standard.
I've tried changing the linker flags to -lcurl.3 in an attempt to
force it to link against the older version, but that doesn't help
since all the dylibs are symlinks to the same file. The linker
appears to embed the full path to the image in the executable. I was
under the impression that setting the deployment target to 10.4 would
take care of issues like this.
I need to have the SDK set to 10.5 because I used some API in Tiger
that no longer work in Leopard, and I need new Leopard API to work
around my previous Tiger hackery. Is there something I can do to get
this working? Surely I don't have to resort to dlopen()!
Thanks,
Stephen
