Comment:
This might not be as easy as it seems. In my merge tree, I tried removing
the pyprocessing spkg, and edited `spkg/install` and `spkg/standard/deps`
to get rid of the rules relating to building pyprocessing. Based on this
tree with pyprocessing removed, I cut a source tarball and parallel
compile (using "export MAKE='make -j4'") everything from source. Trouble
kicks in while compiling the Sage library. Here's a relevant snippet from
the install log:
{{{

The build error cannot be due to the patches or updated spkg's in my merge
tree. I also tried cutting a source tarball of my merge tree (with
pyprocessing intact where it is), and compile everything from source. This
went OK. Removing pyrocessing would need to wait after releasing Sage
4.3.2.alpha0. I'm putting this back to "needs work". The likely place to
look is the file `devel/sage-main/setup.py`, especially the following
function:
{{{
#!python
def execute_list_of_commands_in_parallel(command_list, nthreads):
"""
INPUT:
command_list -- a list of pairs, consisting of a
function to call and its argument
nthreads -- integer; number of threads to use
OUTPUT:
Executes the given list of commands, possibly in parallel,
using nthreads threads. Terminates setup.py with an exit code of
1
if an error occurs in any subcommand.
WARNING: commands are run roughly in order, but of course successive
commands may be run at the same time.
"""
print "Execute %s commands (using %s threads)"%(len(command_list),
min(len(command_list),nthreads))
from processing import Pool
p = Pool(nthreads)
for r in p.imap(apply_pair, command_list):
if r:
print "Parallel build failed with status %s."%r
sys.exit(1)
}}}
