Hello,
 
I'd like to present a new project called "ABI Navigator" for searching binary symbols (functions, methods, global data, etc.) in open-source libraries: https://abi-laboratory.pro/index.php?view=navigator
 
The project allows to find out in which versions of libraries some symbol is defined, added, removed or changed. The data is taken from the ABI Tracker project (238 libraries and 0.9 million symbols currently): https://abi-laboratory.pro/tracker/
 
Example for _ZNK6QColor6rgba64Ev from libQt5Gui.so: https://abi-laboratory.pro/index.php?view=navigator&symbol=_ZNK6QColor6rgba64Ev%40%40Qt_5
 
The project aims to help Linux developers and maintainers to resolve issues with missed symbols and navigate through the reports in the ABI Tracker.
 
Have you ever encountered the "undefined reference" error or want to know whether the symbol is _stable_ enough to use in your code? Try to find it in the ABI Navigator!
 
Enjoy!
