Updating more libraries to hind their symbols by default seems reasonable to me. Any cases where we're using unintentionally referenced symbols should be addressed, as you said. [quote="bhatsach, post:1, topic:7981"] However other packages just have the visibility headers defined but not enabled in compile flags [2]. [/quote] The symbol visibility headers are used primarily for Windows, where symbols must be declared publicly, and implicitly referencing symbols will not work. --- [Visit Topic](https://discourse.ros.org/t/set-symbol-visibility-to-hidden-for-rmw-and-rcl-packages/7981/2) or reply to this email to respond.
