Description

It can be compared with the well known ccache. It has some unique features :

• it uses a LD_PRELOADed shared object to catch invocations to cc1, cc1plus and as.
• consequently, it transparently supports all build methods.
• it can cache gcc bootstraps.
• it can be combined with distcc to transparently distribute compilations.

News

• 2004-03-28: cachecc1-0.3:
  • Arch repository available at http://cachecc1.sourceforge.net/arch
  • A MD4 based hash is used. It is slighly slower but a lot more secure than the previous hash.
  • cachecc1 and followcc1.so have been merged into cachecc1.so. This recovers the speed loss caused by the hash change.
  • Can collaborate with distcc (cached and distributed bootstraps of gcc work well with recent gcc versions).
  • Most environnement variables have been renamed (for instance, CACHECC1_DIR replaces CACHECC1DIR).
• 2004-01-31: Project moved to http://sourceforge.net/projects/cachecc1
• 2003-11-25: cachecc1-0.2: Solaris port.
• 2003-10-08: cachecc1-0.1: first public release.

Installation

• Get it from http://sourceforge.net/project/showfiles.php?group_id=91955 and extract it.
• Or, with tla :
  • tla register-archive http://cachecc1.sourceforge.net/arch
  • tla get bpc@users.sourceforge.net--cachecc1/cachecc1--mainline
• Run make in the source directory.
• Copy the cachecc1.so binary in a directory of your choice.
• If you plan to use cachecc1 with distcc

Usage

• CACHECC1_DIR: location of the cache
• LD_PRELOAD : path to the cachecc1.so shared object

	TWTOOLS=$HOME/dev-bpc/cachecc1/bin
	export CACHECC1_DIR=$HOME/cachecc1dir
	export LD_PRELOAD=$TWTOOLS/cachecc1.so
