using ccache

How do I use ccache to improve recompiling speed?
For example, I build firefox daily from MOZILLA_1_8_BRANCH on my archlinux.Can somebody refresh my memory with how to use ccache when recompiling firefox to speed things up?

I include

Code: Select all

export PATH=/usr/lib/ccache:$PATH

at the beginning of my build script. If I don't want to use ccache for a particular build I just comment that line out. I didn't have to symlink anything to make it work.

I use the following in autofox.sh:

Code: Select all

export CC="ccache gcc"
export CXX="ccache g++"
export CCACHE_HARDLINK="1"
export CCACHE_DIR="/path/to/ccache/directory"

Hendikins, how do you create the tarball?
I'm doing cd ./firefox-release/xpinstall/packager && make MOZ_PKG_APPNAME=firefox
but it won't staticly link the xpt files in /components/ ( the build itself is static ).

I don't bother with the packaging script. I simply compress /dist/bin

Code: Select all

tar -C dist -jhcf $STAGEDIR/$buildfilename bin/

Another way (better?) to make the tarball is "cd ./firefox-release/browser/installer && make" or "make -C firefox-release/browser/installer", assuming firefox-release is your objdir. Use "make installer" for the installer.

CrazyFred, make -C firefox-release/browser/installer gave errors.

Hmm, what sort of errors ?

CrazyFred:

Code: Select all

make: Leaving directory `/home/hussam/packages/firefox/mozilla/firefox-release/browser/installer'

I can howerver build the installer 'firefox-2.0a1.en-US.linux-i686.installer.tar.gz' using 'make -C firefox-release/browser/installer installer '

Actually, that reminds me of hitting the same bug a few days ago. I bet that just the make will work now that you've done the make installer.

CrazyFred, still 'make -C firefox-release/browser/installer' fails but 'make -C firefox-release/browser/installer installer' works with same problem.
any idea?

Have you tried disabling ccache for packaging ? The Linux tinderbox seem to go make installer, make and don't have any problems.

CrazyFred, I tried again. I'm still getting the error above when running 'make -C firefox-release/browser/installer'
but for some reason, 'make -C firefox-release/browser/installer installer' still works and I'm making the installer ( like the one for win32 ).
