[SOLVED] Running Synfig after building

When I ran synfig-build.sh, there was no bin folder/Synfig executable in the same directory as synfig-build.sh. After running synfig/autobuild/fedora-crosscompile-linux.sh and then synfig-build.sh, the bin folder showed up. I got synfig-build.sh from the post [tips]how to build synfig from git (Fedora 18)

Is it used for the number of CPUs being used while building?

It did not work. For example, I made a small change in circle.cpp, I ran make -j1 in the mod_geometry directory, modules directory and synfig-core directory; but nothing changed in the program.
