`ccache` is a program which can save compiling cache, speeding up recompile's of big software. First install it:
|
|
|
|
``` shell-session
|
|
sh# emerge -av dev-util/ccache
|
|
```
|
|
|
|
And create a configuration file for `ccache`.
|
|
|
|
``` title="/etc/ccache.conf"
|
|
cache_dir = /var/cache/ccache
|
|
|
|
max_size = 20G
|
|
umask = 002
|
|
hash_dir = false
|
|
compiler_check = %compiler% -dumpversion
|
|
|
|
compression = true
|
|
compression_level = 1
|
|
```
|
|
|
|
Configure `portage` to allow `ccache` for specified packages:
|
|
|
|
``` title="/etc/portage/env/enable-ccache.conf"
|
|
FEATURES="ccache"
|
|
CCACHE_DIR="/var/cache/ccache"
|
|
```
|
|
|
|
Then for every package with which you want to use `ccache` add them:
|
|
|
|
``` title="/etc/portage/package.env/ccache"
|
|
sys-kernel/gentoo-kernel enable-ccache.conf
|
|
sys-kernel/firefox enable-ccache.conf
|
|
...
|
|
```
