  1. Jan 31, 2010 · Sometimes, ABI changes are unavoidable. When this happens, any programs that use that library will not work unless they are re-compiled to use the new version of the library. If the ABI changes but the API does not, then the old and new library versions are sometimes called "source compatible".

  2. Apr 24, 2024 · An ABI, or “Application Binary Interface” is analogous to an API but expressed in compiled code instead of source code. In a Java application, for example, the API of a library would be the library’s source code, and the ABI would be the class files that the application works in terms of. Often, the ABI of a piece of software is directly ...

  3. Jan 5, 2024 · Therefore, while API changes may require adjustments in how software components interact at the source code level, they do not permanently disrupt the binary compatibility. Maintaining ABI Stability. Given the potential disruptions caused by ABI changes, maintaining ABI stability, especially in shared libraries, is paramount.

  4. A "stable" ABI is one that does not change incompatibly between versions. Nowadays, most compilers support at least one such ABI for C++; MSVC was the slowest to achieve this (2019 vs 2004). A "single" or "standard" ABI is one that everyone on a given platform is expected to use. For C++, this is the case on most Unix systems since the early ...

  5. May 9, 2021 · This is the sort of thing "ABI" and "ABI Breakage" refers to in the context of the "C++ ABI Breakage" debate. The ability (or not) to change the private variables of an STL class from one version of a C++ release to another. Changing such private variables (along with a few other things) would be deemed an ABI Break.

    Summary Define API stability guarantees for your project. Ensure version numbers are changed as appropriate when API changes. API and ABI At a high level, an API – Application Programming Interface – is the boundary between two components when developing against them. It is closely related to an ABI – Application Binary Interface – which is the boundary at runtime. It defines the ...

  8. Oct 14, 2015 · Adding a field to a structure is an API change, but not one that breaks compatibility with existing source code. But changing the size of a structure is an ABI change that breaks compatibility with existing compiled code. The two are basically independent; you can also make changes that break API but not ABI (such as renaming a field in a ...
