Hello, I'd like to present a new project called "ABI Navigator" to search for 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 reused from the ABI Tracker project (238 libraries and 0.9 million symbols currently): https://abi-laboratory.pro/tracker/ Example for symbol gst_stream_new from libgstreamer.so (GStreamer): https://abi-laboratory.pro/index.php?view=navigator&symbol=gst_stream_new 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 import by your code? Try to find it in the ABI Navigator! Enjoy!
