I'm trying to build an app that uses libcurl on 10.5.
However, it must also run on 10.4. (Yes, I could build

On 10.5, Xcode seems to prefer libcurl.4.dylib, even
though other earlier versions are available. Of
course, on 10.4, only libcurl.3.dylib is available.
I've tried everything I can think of, including (but
not limited to ;) ) using install_name_tool, -weak
linking, and so on, but to no avail.
So, I'd like to know how I can force Xcode to link
against libcurl.3.dylib instead of simply choosing the
latest version available.
I tried using -lcurl.3 in the build settings, but it
seems to ignore me.
-l/usr/bin/libcurl.3.dylib
he Linker will always use a library you provide explicitly by its full
path. If you just use the library's canonical name (e.g. -lcurl), it
will apply the search heuristics to pick the one it prefers by
location, type (.dylib over .a), and version.
