Header file cache for GCC preprocessor

hcache

Hcache is a header file cache for GCC preprocessor.

Hcache is a band-aid for slow build times when building over a network filesystem such as ClearCase MVFS. The caching strategy is very simple, hcache lazily copies all the included header files to your local home directory. The cache is never invalidated which can cause build failures if the header files change.

Usage

Hcache is used as a wrapper for GCC, for example:

hcache gcc -Iinclude -o test test.c

By default, $HOME/.hcache is used as the cache directory. The default can be overridden with the environment variable $HCACHE_DIR.

The file config in the cache directory can be used to specify the paths at which include files will be cached. The format of the file is a single regular expression. For example,

^\/foo

means that include files with paths starting with /foo are cached.
