Support Information¶
Supported Platforms¶
For Botan 3, the tier-1 supported platforms are
Linux x86-64, GCC 11 or later
Linux x86-64, Clang 14 or later
Linux aarch64, GCC 11 or later
Linux ppc64le, GCC 11 or later
Windows x86-64, Visual C++ 2022 or later
These platforms are all tested by continuous integration, and the developers have access to hardware in order to test patches. Problems affecting these platforms are considered release blockers.
For Botan 3, the tier-2 supported platforms are
macOS x86-64, latest XCode Clang
iOS aarch64, latest XCode Clang
Windows x86-64, latest MinGW GCC
Android aarch64, latest NDK Clang
Linux arm32, GCC 11 or later
Linux x86-32, GCC 11 or later
FreeBSD x86-64, Clang 14 or later
Some (but not all) of the tier-2 platforms are tested by CI. Everything should work, and if problems are encountered, the developers will probably be able to help. But they are not as carefully tested as tier-1.
Of course most other modern OSes such as QNX, AIX, OpenBSD, NetBSD, and Solaris also work just fine. Some are tested occasionally, usually just before a new release. But very little code specific to these platforms is written by the primary developers. For example, any functionality in the library which utilizes OpenBSD specific APIs was likely contributed by someone interested in that platform.
In theory any working C++20 compiler is fine but in practice, we only regularly test with GCC, Clang, and Visual C++. Several other compilers (such as Intel and Sun Studio) are supported by the build system but are not tested by the developers and may have build or codegen problems. Patches to improve support for these compilers is welcome.
