Supported platforms, compilers and languages
This page collects information on platforms (operating systems), compilers and source code languages that are supported by the latest released ccache version, currently 4.13.1. The information below aims to be correct, but new versions of e.g. an OS or a compiler may introduce new behavior that breaks some of ccache's assumptions.
If you want to contribute new or updated information, please open an issue or maybe even create a pull request for the web site repository.
Support levels
| Level | Description |
|---|---|
| A | Supported. Built and tested regularly and before new releases. High attention to bug reports. |
| B | Partially supported. Not part of the test procedure before a new release, but known to work in many scenarios. Bug fixing and testing might depend on contributions from the community. |
| C | Not officially supported. Has known compatibility gaps. May work in some scenarios |
Run-time support (i.e., using ccache)
