Glibc 是提供系统调用和基本函数的 C 库，比如open, malloc, printf等等。所有动态连接的程序都要用到它。
GLib 2.30.0 Changes:
- GDBus gained a high-level object manager and code generation facilities that make use of it.
- An extensible TLS database was added where certificates and keys can be found and used, laying the foundation for integration with smart cards and other key stores.
- HMAC hashes are now also supported.
- Atomic operations were expanded to include bit operations (and, or, xor) and so that all operations are supported on pointer-sized operands.
- Bitlocks now work on pointer-sized operands.
- GApplication now supports non-single-instance applications.
- Other enhancements and many bugfixes were made
