Requirements
Here we describe the software versions that we use for continuous integration testing. Of course, Fast Downward might work for other versions that we don't test, but we can't guarantee that. We use the following rules to decide which versions of operating systems, compilers, Python and other tools we test:
Python: we test all versions within their lifespan, given that they are available on GitHub Actions.
LP solvers (CPLEX and SoPlex) and OSI: we test one specific version. We only upgrade the tested version if the current version no longer works or someone wants to test a newer version instead.
GCC and Clang on Ubuntu: we test the default GCC and Clang versions in the latest two LTS releases of Ubuntu and the latest GCC and Clang versions available via apt on the latest Ubuntu release on GitHub Actions.
Clang on macOS: we test the default AppleClang compiler on the latest two macOS versions available on GitHub actions (currently there is only one macOS version).
MSVC on Windows: we test the default MSVC compiler which comes with the Visual Studio version on the latest two Windows versions available on GitHub actions.
- CMake: we test the default version of CMake available in the latest two LTS releases of Ubuntu.
According to the above rules, this is the current list of tested versions:
- Python: 3.6, 3.7, 3.8 (TODO: test Python 3.9)
- CPLEX: 12.9
SoPlex: 3.1.1
- OSI: 0.107.9
- GCC: 7, 9, 10
- Clang: 6, 10, 11
macOS: Catalina 10.15 with AppleClang 12.0.0.12000032
- Windows: Visual Studio Enterprise 2017 (MSVC 19.16.27045.0) and 2019 (MSVC 19.28.29336.0)
- CMake 3.10.2 and 3.16.3
[Jendrik: I think it would be best to add this list to the repo, not the wiki. This will make it easier for people to run Fast Downward versions from Zenodo, for example.]
