/* * MANIFEST: use of SCons in project config file to build itself * * SCons has a Repository feature, introduced in SCons 0.09, that was * designed to work well with Aegis. */ /* * The build_command field of the project config file is used to invoke * the relevant build command. This command tells SCons where to find * the rules. * * Our chicken-and-egg dilemma is this: we want to use the version of * SCons under development in an Aegis change to build itself. But the * pieces of SCons are likely only partly in this change, and partly in * baselines. * * Python only imports things on a module-by-module basis--which is to * say, once it finds __init__.py in a given directory, it assumes that * all other files in that module are in the same directory. But that's * not the way Aegis works, because if a file hasn't changed on the * branch, it will only be in its parent's baseline directory. * * Aegis' mechanism for working around this sort of problem is to make * symlinks to the proper baseline versions of each file, which makes * it look like everything is in the local tree. That's unattractive, * though, because we really want to eat our own dog food and use the * SCons -Y options to pull things from the baseline repositories. * * So our solution (suggested by Anthony Roach) is a bootstrap.py script * that does some Aegis-like searching through the baseline directories * and makes a bootstrap copy of the version of SCons under development * that we can use for building. After it makes this copy of SCons, it * executes it with the same command-line arguments we supplied (and * setting $SCONS_LIB_DIR to the right directory) so we can use it * here with command-line options as if it were SCons itself. (Note, * however, that bootstrap.py only understands the specific command-line * options already in use here, so if you change the call below to add * some other SCons options, you may have to modify bootstrap.py to * recognize them. * * The ${Source bootstrap.py} substitution finds bootstrap.py wherever * it may be in the Aegis baselines. * * The long -Y${SUBSTitute...} substitution takes the Aegis baseline * search path and turns it into the right -Y command-line options for * SCons. * * The rest of the substitutions (${DEVeloper}, etc.) should be obvious. * * Look in aesub(5) for more information about command substitutions. */ build_command = "python1.5 ${Source bootstrap.py} -Y${SUBSTitute : \\ -Y $Search_Path} date='${DAte %Y/%m/%d %H:%M:%S}' developer=${DEVeloper} version=${VERsion} change=${Change}"; /* * SCons removes its targets before constructing them, which qualifies it * for the following entry in the config file.
