For a full and more recent version of scons, +please consult http://www.scons.org + +Including this scons distribution to your archive will add +about 63kb (compressed) , while including the necessary +kdescripts (admin/ directory, configure, autom4 cache stuff, +Makefile.in) can add easily 500kb (compressed). + +To compile with the scons distribution : +* unpack it with : + tar xjvf admin/scons-mini.tar.bz2 +* compile the program with : + ./scons (instead of just 'scons') +* install the program with : + ./scons install (instead of just 'scons install') + +More options : +* clean the object files with : + ./scons -c +* uninstall the program with with : + ./scons -c install +* create a package : + ./scons dist + +------------------------------------------ +MORE TIPS + +** static libraries ** +With Makefile.am, one had to make static libraries all the time +because it did not allow having source code in other directories. +This is not the case anymore with scons, so you can specify +sources in other directories relative to the sconscript file, ie: + test1_sources = ['mainfiles/main.cpp', 'otherfile/program.cpp'] + myenv.Program( target = "test1", source = test1_sources ) +To encourage you to switch to the new scheme, the static library +helper has been omitted (look at the end of kde.py if you need one) + +** libtool ** +The LaFile build tool is a cheat that allows klibloader to load +.so files without complaints. If you need real libtool support +you can have a look to the libtool directory : it can work but +remember that libtool is broken on many systems (invalid flags +among others), so when you can work without libtool +(small projects especially), just do it. + +** moc processing ** +As stated above, you should always add #include "foo.moc" +for your qt classes (Q_OBJECT) to save precious compilation time. + +** using a cache ** +It is a good idea to enable the cache feature in SConstruct, +especially if you are doing experiments (it saves your computer +from recompiling the same files over and over again ..). + +** threading ** +myenv.AppendUnique( CPPFLAGS = ['-DQT_THREAD_SUPPORT', '-D_REENTRANT'] ) + +** final notes *** +A medium-sized project containing several targets, libraries and data +files can be converted very quickly. +Also, remember that SConscript files are actually python scripts .. +you can use whatever python feature you want in them, ie: "for" loops, +this is how the kde helpers work (KDEprogram, KDEshlib ..). + +If you are stuck, you can also have a look at more complicated +bksys-based projects like kdissert or kshaderdesigner + +The scons man page and the wiki can be very useful, do not forget to +consult them when you encounter an issue + +------------------------------------------ + +I hope you will enjoy this alternative to the autotools +scripts for kde programming, at least as much as I do : +http://freehackers.org/~tnagy/kdissert/index.html + +Happy kde hacking, + +Thomas Nagy, 2004, 2005 <tnagyemail-mail@yahoo^fr> + |
