The version of Electric Make shipped with SparkBuild 1.0 is pretty similar to the emake that ships with ElectricAccelerator v4.5, so you shouldn't have any trouble using SparkBuild with SBSv1. If you encounter any problems, be sure to report it here, and we'll help you out.
Thanks. Our current ECA build system takes around ~28 hours for compilation. SBSv1 has some limitation on dependency builds. Just wondering, would spark build make any difference in compilation time or not with sub builds.
