Sparkle is built with
-fvisibility=hidden -fvisibility-inlines-hidden which means no symbols are exported by default.
If you are adding a symbol to the public API you must decorate the declaration with the
SU_EXPORT macro (grep the source code for examples).
Building the distribution package
cd to the root of the Sparkle source tree and run
make release. Sparkle-VERSION.tar.bz2 will be created in a temporary directory and revealed in Finder after the build has completed.
Alternatively, build the Distribution scheme in the Xcode UI.
