GMP-ECM-sys

Rust low-level bindings for GMP-ECM.

Caching the built C libraries

Building the C libraries can take some time. In order to save compilation time, the built libraries are cached in the user’s cache directory as follows:

• on GNU/Linux: inside $XDG_CACHE_HOME/gmp-ecm-sys or $HOME/.cache/gmp-ecm-sys
• on macOS: inside $HOME/Library/Caches/gmp-ecm-sys
• on Windows: inside {FOLDERID_LocalAppData}\gmp-ecm-sys

To use a different directory, you can set the environment variable GMP_ECM_SYS_CACHE to the desired cache directory. Setting the GMP_ECM_SYS_CACHE variable to an empty string or to a single underscore ("_") will disable caching.
