From a72d2f7f3fb7576067dd2b88864a4231a5109aef Mon Sep 17 00:00:00 2001 From: Craig Scott Date: Mon, 20 Sep 2021 11:20:46 +1000 Subject: [PATCH] Fix main() not being visible on Android A recent change refactored the call to qt_internal_add_executable(), but that had the unintended side-effect of changing the symbol visibility from public to hidden. That meant that main() became hidden, so while apps still built successfully, they could not be run. Restore the original symbol visibility to fix this regression.
