Bug 1619

Summary:	build speed of ns-3-dev is slow
Product:	bake	Reporter:	Hajime Tazaki <tazaki>
Component:	bake	Assignee:	Daniel Camara <daniel.camara>
Status:	RESOLVED WORKSFORME
Severity:	major	CC:	ns-bugs, tomh
Priority:	P5
Version:	unspecified
Hardware:	All
OS:	Linux

Description Hajime Tazaki 2013-04-04 11:34:14 UTC

It seems that bake explicitly specified the value of "-j" option (default 1) even the command does not have the option. that makes './waf -j1' to build ns-3-dev while waf can detect the number of processors and internally assigns parallel jobs to speed up the build.

this is resolved, correct?

I think not yet.
As Daniel mentioned to change this behavior, I'm glad if we cloud include this fix in ns-3.17, if time frame permits.

Fix at changeset 208

using changeset:   210:9f23b7abe961

it seems inline modules should also be updated.

I temporary pushed the workaround. Daniel, please confirm it whether it works fine.
