[Freeswitch-users] Build slow, I may have a solution for you.

I have been working on many build improvements to the FreeSWITCH(tm)
build system as you know. The most common complaint I have had lately
is how long it takes to ./bootstrap.sh && ./configure && make. I have a
few things in place to address this now. Please read on.
./bootstrap.sh speed: I have nothing in tree yet, but some plans that
should help this, please stay tuned.
./configure speed: in my testing using the -C option on configure to
use a cache file will significantly speed up your configure. In my
testing it was an improvement from 2 min 51 sec to 1 min 54 sec. I
strongly suggest using -C when you configure. If anyone knows of a way
to make this the default (I have not yet found a way) I would appreciate
it. Additional speedups in the works on this.
Make speed: I now have make -j working at least for the core, all of
it's dependencies, and all the default modules and their dependencies.
In my test setup, using -j on make increased the build speed on fresh
checkout from 4 min 2 sec to 1 min 33 seconds.
I strongly suggest using both of these build options.
Build speed test machine specs:
Dual Intel(R) Xeon(R) CPU 5130 @ 2.00GHz server (4mb cache)
gcc (GCC) 3.4.6 20060404 (Red Hat 3.4.6-3)
clean checkout of svn trunk r4844
autoconf (GNU Autoconf) 2.59
automake (GNU automake) 1.9.2
ltmain.sh (GNU libtool) 1.5.22 (1.1220.2.436 2007/02/17 08:23:50) (this
is actually 1.5.23b as available on the gnu website at
http://www.gnu.org/software/libtool/ under Development Release of Stable
Branch GNU Libtool 1.5.23b 17 February 2007 )
configured with no special options but -C and --prefix
time for the make portion only with -j
time for the make portion only without -j
time ./configure -C --prefix=/usr/local/freeswitch.dashj
